Essays on Diaphragm

Introduction

The study of human body movement assists in understanding different biomechanical, psychological, and physiological mechanisms of the body. Taking care of a newborn from the time of birth to the age of about twelve months requires the mother or the caregiver to understand some concepts necessary for the survival of the baby. According to Davis, Cladis & Motoyama (2011), the breathing pattern of newborns from up to the age of six months is purely diaphragmatic (abdominal), hence; the need to understand various positions that allow the infant breath effectively. Understanding diaphragmatic breathing patterns acts as one of the major clinical ...

Cardiovascular system

The cardiovascular system is also known as the circulatory system, and it is the body’s transportation system that comprises the heart, blood vessels, and blood. The system does the work of transporting oxygen, hormones, cellular waste products and nutrients to all the parts of the body. The use of blood transports all the products, and it is approximated that the body of an adult makes use of five liters of blood to transport the products from one part to the other. Blood is pumped from the heart through the arteries then gets into body tissues through capillaries (Inner ...

Chronic obstructive pulmonary disease (COPD) refers to emphysema and chronic bronchitis. Stoller claims that COPD has been the interest of many researchers recently. The disease caused about 2.5 million deaths in 2000 (Stoller, 2012). Normally, there are two lungs in the chest. Lobes are sections that make up lungs. Ribcage protects the lungs. They remove carbon dioxide from the body and bring oxygen into it. The nose and the cough are the ways in which lungs protect themselves. People breathe in air through the mouse or nose (Thoracic.org, 2015). Then the air moves down the trachea. The epiglottis controls ...

GERD: Introduction

“Gastroesophageal reflux disease (GERD) is a syndrome wherein the stomach’s contents of those in the small intestine constantly move up into the esophagus. The rearwards motion of the contents is called a “reflux.” This condition results in the person being subjected to episodes of heartburn, a stinging sensation felt under the sternum part of the chest, is the initial symptom of heartburn; this is traditionally felt after the person has a heavy meal, or lies down or lifts a heavy object immediately after eating. If a person is consistently experiencing bouts of reflux and extreme heartburn, then ...

Abstract

Worldwide, ovarian cancer is ovarian cancer is the sixth most diagnosed cancer and is responsible for the most deaths annually than any other disease of the female reproductive system. It has a poor prognosis because the symptoms are vague even into Stage IV of the disease. Epithelial ovarian cancer constitutes about 90% of diagnosed cases. Research has demonstrated that hormone therapy, chronic pelvic inflammation, and BRCA1 and BRCA2 germline pathogenic variants are factors in the etiology of ovarian cancer. BRCA1 and BRCA2 is also associated with breast cancer, pancreatic cancer, fallopian tube cancer, prostate cancer, and primary peritoneal cancer. ...

Introduction

The exchange of respiratory gas is limited by the capacity of the respiratory muscles to circulate air in the lung. Ventilation fails when muscles do not have the capacity to cope with the load brought by the mechanics of the pulmonary system. It is crucial to comprehend the mechanics of respiration/breathing not only for purposes of diagnosing how the system has failed and to offer the correct prescription for treatment of the failure, but to be capable of providing the most effectual temporary respiratory support through the use of a mechanical ventilator, as well. The first category explains the ...

Liver is the largest ‘gland’ of the digestive system. It is located right under the dome of the diaphragm, coated by the capsule. It is distinguished the liver’s convex upper surface adjacent to the diaphragm, and a lower, downwardly facing and in contact with the back and abdominal organs. On the part of the upper surface of the liver it can be seen its right and left lobes, the boundary of which is the crescent liver ligament. To the lower surface of the right lobe there is a gallbladder, close to the deep groove of the liver there ...

Mechanical ventilation (MV) causes oxidative stress that is responsible for adverse consequences on organs. In a situation of MV, the excessive pressure impairs the function of the mitochondrial respiratory chain leading to oxidative and nitrosative stress (Kavazis, 2009; Hafner et al., 2014). MV is commonly associated with hyperoxia where an excess of oxygen is provided. In such a case an oxidative stress can be induced when the oxygen pressure in the alveolar exceeds that of the normal breathing conditions because the biological system is not able to readily detoxify the environment from components such as reactive oxygen species (ROS) ( ...

The cardiovascular and respiratory systems are largely responsible for the transportation of oxygen and carbon dioxide through the body. Respiration consists of both inspiration and expiration. These actions are the methods by which essential oxygen is exchanged with harmful carbon dioxide. While oxygen is brought into the lungs during inhalation to be processed throughout the body, carbon dioxide is brought during exhalation to be removed from the system entirely. Once the oxygen has reached the lungs it is taken up by the bloodstream in order to be distributed to the various cells that require a constant exchange of nutrients ...

The Dome of the Rock is the first imperial structure made for Islam and also the second most important Islamic site after Mecca. It was built in the 7th century in Jerusalem by Caliph Abd al-Malik, also known as the Umayyad. As an edifice, the Dome of the Rock is not a mosque, but more of a religious shrine. Like Mecca, the Dome of the Rock stands on a sacred stone this is the period of the Islamic culture, which also involves Mohamed. Mohamed was born in the 6th century in Mecca. The Dome of the Rock has its ...

The process of inhalation or inspiration can be explained simply by the intake of air. In some cases, this process is further described as the transfer of the oxygen to the bloodstream and then to the blood cells. Further, this is followed by the release of the carbon dioxide from the cells to the bloodstream and pumping it to the lungs, from where the waste carbon dioxide is expelled to the environment. The oxygen enters into the body from the outside environments through inspiration. This process of inspiration includes the contraction of the diaphragm along with the internal and ...

Gastro esophageal reflux disease is a digestive disorder that has effects on the lower esophageal sphincter, which is the ring that is found between the stomach and esophagus (Mayo Clinic, 2016). The contents of the stomach get backed up in the esophagus. This condition is experienced especially when the lower esophagus sphincter becomes weak hence allowing the contents of the stomach to flow back into the esophagus (Doig & Huether, 2014). This disorder is known to cause heartburn to pregnant women. GERD has proved to be the most common outpatient gastroenterological diagnosis witnessed in the United States. The prevalence rate ...

Summary

This experiment is about the static calibration of a differential pressure transducer. Test measurements are done to find the range of input and output of the transducer, and to determine the “best-fit” line that models how the voltage reading would equate to the real pressure measurement. The input pressure comes from a hydraulic ram with pressure gauge. The output of the differential pressure transducer is in voltage, and is measured by a digital voltmeter. The input pressure is varied from 0 to 6 bar, and the three voltage readings are recorded for each pressure step value.

Introduction

The respiratory system can be termed as a biological system comprising of specific structures and organs that are used, by an organism, in the respiration process. It participates in the exchange together with intake of oxygen and carbon dioxide between an organism and its environment (Seeley, Stephens and Tate).

In vertebrates that breathe air, respiration occurs in the organs of respiration, lungs. The air passage to the lungs for supply of oxygen to the body is called inhalation, while the air passage away from the lungs to release carbon dioxide is called exhalation. In human beings, the anatomical characteristics ...

Respiration is essential in the survival of all living organisms. It is a process where gas exchange occurs in all biological organisms. In the case of animals such as humans, respiration is affected by the ratio of the concentration of oxygen and carbon dioxide in the body. The human body generally requires oxygen gas because it is only through this aerobic respiration by which metabolic functions are assumed to maintain homeostasis. In humans there is a specific organ system which is solely dedicated to respiration known as the respiratory system. The human respiratory system constitutes different types of organs which performs ...

Exercise 1: Anatomy of the Respiratory System

What are the two functions of the larynx? Larynx is a cartilaginous and a muscular structure while holds vocal cords together. It is used by human beings to talk, swallow and breathe. It is lined by the mucous membrane hence forming part of the respiratory system. Larynx protects the airways by closing quickly after mechanical simulation hence stopping respiratory and curbing the entry of foreign substances into the airways. The larynx also produces sound, controls ventilation and acts as a sensory organ.

Where does gas exchange take place in the lungs?

Gaseous exchange occurs in the lungs and for it to take place; there is the need for a place where ...

ABSTRACT

Muscular dystrophy disorders are hereditary neuromuscular disorders in which the skeletal muscles deteriorate progressively due to loss of the functional protein dystrophin encoded by the DMD gene. There are many types of muscular dystrophy and they are classified based on the genetic mechanisms involved. Muscular dystrophy symptoms are usually caused by mutations in the link between cytoskeletal and basal lamina proteins since dystrophin is a sarcolemmal membrane protein (Meregalli M, 2013). Loss of ambulation is also an important clinical milestone in the clinical diagnosis of muscular dystrophy. Respiratory muscles, particularly the intercostal and diaphragm muscles are also affected by muscular ...

Optical microscopy – is the technical field of studying objects using optical microscopes. Optical microscopes are devices that use visible light rays as both eye works in the optical wavelength range. So, optical microscopes could not have diffraction limits resolution less than 0.2 micrometers (200 nanometers) and with maximum magnification up to 2000 times. The human eye is a biological optical system, characterized by a certain resolution - the smallest distance between the elements of the observed object, while they can still be distinguished from one another. For a normal eye, at a distance from the object to the so-called. best vision distance (D = ...

1. Components and mechanisms of the respiratory system The respiratory system is the system that allow humans and animals to breathe. The main function of the system is to provide oxygen to the body through the blood. Breathing involves two main actions: inhaling and exhaling air. Inhalation brings oxygen into the body via the blood and exhalation chases out carbon dioxide. The respiratory system is composed of different tissues and organs, including the airways, lungs, bloods vessels and muscles connected to each other to assure a proper breathing process (National Heart, Lung and Blood Institute, 2012). The airways ...

The trachea is the tube that connects the bronchi to the throat. The bronchi are further trachea divisions. One proceeds to left lung while the other into the right one. In the lungs, each bronchi separates into smaller bronchi. The broncheoli are bronchi branches, which are smaller tubes that amount to pulmonary alveolus. The pulmonary alveoli are tiny air sacs delineated through single-layer membranes that have blood capillaries on either end. The lungs’ inner surfaces are where gaseous exchange takes place due to the alveoli structure. The lungs are a pair of organs within the vertebrates (Collins & Eric, 2012). For ...

Background.

Gastrointestinal tract is a series of organs starting at the mouth and ending in the anus. The movement of various muscles in GI tract and release of enzymes and acid in the stomach initiate digestion of food. The upper GI tract is made up of the organs mouth, esophagus, stomach, small intestine and duodenum1. Gastroesophageal reflux is the process of backing up or refluxing of the stomach content to the esophagus or mouth. It is a normal developmental process observed in many healthy infants. Most episodes of GER are asymptomatic, though occasional spit up is observed in GER in infants. ...

Comparison between invasive & non-invasive ventilation in managing flail chest

Abstract Background Invasive ventilation has been beneficial with the provision of the airway defense for patients with respiratory complications and blunt injury such as the flail chest. It increases the airway defense and consequently minimizes the risk of reparatory related infections. Furthermore, invasive ventilation has the ability to allot the flow of lower tidal volumes. On the other hand, non-invasive ventilations involve the use of a ventilator support without the invasive artificial airway. This type of ventilation has been in a wide use and it has become popular within the previous two decades. The flexibility nature of the method ...

Control Valves

A valve is a control device that is utilized in adjusting the flow rate of a fluid in a pipe (Doddannavar, Barnard, and Ganesh, 2005). This implies that the flow rate will change as the valve opens and closes either partially or fully, thus providing some obstruction to some extent (Rennels and Hudson, 2012). The valve comprises a flow passage in which the flow area can be varied. Operation of valves in most scenarios is manual. In cases where the valves are operated automatically, electromechanical actuators are used. The electromechanical actuators can include electric motors or pneumatic actuators that are motorized by air ...

Amyotrophic lateral sclerosis (ALS) which is also refered to by the public as Lou Gehrig's disease is a neurodegenerative disease that affects the brain and spinal cord. It is a form of motor neuron disease, which is rapidly progressive with degeneration of both upper and lower motor neurons. The implication of this is that there is associated complication leading to progressive weakness of muscle, atrophy and some other major voluntary muscular effects. This is because the attack is majorly on the nerve cells controlling the voluntary muscles.

The neurologic condition has been found to have both sporadic and inherited (familial) forms ( ...
