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 ...

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 ...

The respiratory system of dolphins and lions

Dolphin inhale air through blowhole; dolphin do not use nostril like other mammals. Dolphin controls the opening and closing of blowhole through muscle contraction and relaxation. Blowhole which is an external opening takes air to the lungs. The blowhole is located at the tip of dolphin’s head which requires small area of water to be break to take the air. The air is then sent to lung for exchange. Unlike human lungs, dolphin lungs consists double levels of capillaries. Capillaries double layer increases the area of lungs which is resulted in increase in gas exchange rate and efficiency. ...

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 ...

Different organisms occupy different environment, which requires them to adapt to those conditions to ensure their survival. In this sense, there exist vast physical forms between fish and mammals due to their opposing habitats (water and air respectively). However, the main distinguishing characteristic is the structure of their gaseous exchange system.

Fish use water as their respiratory medium. Hence they require an efficient respiratory system. This is because water has less oxygen than air. Fish require a complex respiratory system that will extract oxygen from water. The respiratory system of fish consists of evaginations of epithelium which are known as ...

Developing a Surveillance and Monitoring Program

What action can you take when an outbreak is reported close to home?
Background
SARS (Severe Acute Respiratory Syndrome) is a highly contagious respiratory disease caused by the SARS Coronavirus. Coronaviruses are mostly found in poultry with only a few strains hosted by humans. In the past, Coronaviruses only caused mild flu infections. However, in recent years, the coronaviruses SARS and MERS (Middle East Respiratory Syndrome) have been associated with causal problems for acute respiratory conditions. Further scientific reports have shown that SARS Coronavirus is a new mutant strain origination from animal hosts (Chan & Chan, 2013).

Symptoms

SARS symptoms include ...

Absorption

Absorption is the process through which biomolecules traverse through the GI tract into the circulatory system. Digested food gets absorbed in the small intestinal lumen through four processes, which include active transport, passive transport, endocytosis and facilitative diffusion. The efficiency of absorption of nutrients may be attributed to the large surface area lined up with hair like projections and microvilli cells .

Excretory System

Excretion is the mechanism through which waste products and eliminated from the body and osmotic pressure and homeostasis is achieved in the body . The process of excretion in the body takes place in three stages: filtration, reabsorption and ...

Acute respiratory distress syndrome is a disorder which was first described in 1967. It is one of the most severe and dangerous respiratory system disorders, which is still despite advances of the modern medicine, is associated with high mortality. It may be caused by direct (pneumonia, aspiration, toxic substances inhalation) or indirect lung injury (severe hemorrhage, burns, sepsis, trauma, blood transfusions) (York and Kane 153-158).
Under the influence of the above-written factors in the pulmonary capillaries and interstitial lung tissue accumulates a large number of activated leukocytes and platelets that secrete many biologically active substances. These substances include ...

As a large automobile manufacturer, our core mission is to develop into internationally competitive automobile company. Firstly, to approach the situation, we need to know what impact the economic development has on the environment. Our company cannot successfully pursue pecuniary interest, if its production causes harmful environmental pollution. Every person on the earth, and specifically large automobile manufacturers should have a responsibility to improve the environment. We are aware that, the earth's resources are limited, and due to our overexploitation of energy, it makes the environmental damage incredibly serious. With a more rapid economic development over the past couple ...

Chronic obstruction pulmonary disorders and treatment options

Chronic Obstruction Disorder disease (COPD) is one the most prevalent cause of morbidity across the globe. It is a curable and partially reversible problem which is manifested by an obstruction in air flow and impaired health status. The patients who have frequent attacks of COPD have worst condition along with acute episodes of symptom exacerbation. The objective of the treatment is to avoid the symptoms through controlling it by including the lung functioning and health status. COPD is linked with abnormal inflammatory response of the lungs to noxious gases or particles. Patients below the age of 35 are at ...

Introduction

Approximately 2.5 million individuals in the United States contract pneumonia annually, and 55,000 of those individuals die as a result. In fact, pneumonia was the eighth prominent cause of morbidity and is the number one communicable disease in the United States. Pneumonia is the leading deadly hospital-contracted disease and contributes to a sizable amount of deaths in unindustrialized countries as well. It is a grave illness that can impact individuals in all age groups, but it is especially serious in adolescents, the elderly population, and in people with fundamental medical issues such as ischemia, low blood sugar, and ...

Respiratory alterations occur due to viral infections or invasion of the respiratory system by a foreign substance. The two factors lead to symptomatic coughs that differ depending on the type of infection or invading substance. In our scenario, a 6-year old boy, Kevin, is brought to the doctor for evaluation following a persistent deep cough that has lasted for one week. Before developing the condition one week prior to visiting the doctor, Kevin did not show any health problem. The parents say that the cough is deep and sounds as though Kevin is barking. In addition, Kevin’s cough is so severe ...

In the process of breathing, a molecule of oxygen has to pass through upper respiratory tract and then lower respiratory tract. The upper respiratory tract consists of air passages of the nose, nasal cavity, pharynx, larynx and upper trachea. The lower respiratory tract includes the parts present within the chest cavity namely lower trachea and lungs. The oxygen (from air) enters the respiratory system through nose. Nose is made of bone and cartilage covered with skin and has two nostrils divided by a bony septum. The nostrils are lined with fine hair which blocks the entry of dust and bacteria into ...

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 ...

Should Smoking Be banned from Bars and Eating Establishments?

Smoking is one of the most irritating things in the world. Many people prefer not to sit or even stand next to someone who is smoking. Smoking produces bad smell of tobacco and nicotine which may irritate many people who are near someone who is smoking. Smoking is a killer. This is a strong message that should be clearly adhered to and used to drive people towards the prevention of diseases related to smoking as well as death. Smoking has had very numerous negative effects on the lives of people as it attributed to financial, social and health factors (Beales, 2000). Many ...

The aim of this experiment was to test the effect of the respiratory process on the lung’s tidal volume when standing and when seated. Our null hypothesis was that if the subject was sitting, the tidal volume of their lungs would decrease and if the subject was standing the tidal volume of their lungs would increase. Throughout this experiment the rate of the tidal volume was recorded along with the total amount of tidal volume for each respiration process that is when both standing and sitting.
After recording the data that we collected from 5 tidal volumes ...

Introduction

Air food and shelter are the three basic necessities of life where air is the most essential elements for a human body to live and survive. Air is nothing but a mixture of oxygen, vapors, inert gases, and nitrogen which make up to 99.9 percent of it. In turn, human releases carbon dioxide which can be harmful for all the living creatures that are plants, animals and human being . There are numerous kinds of pollution. Its causes and effects have been largely discussed in many platforms. Some of the effects that are well known are development of holes in ozone layer, ...

Cardiomyopathy is the measurable impairment of the myocardium function for any cause, normally causing heart failure. Cardiomyopathy is commonly associated with signs such as dyspnea also referred to as shortness of breath, and legs swelling also referred to as peripheral edema. Persons suffering from cardiomyopathy are usually at risk of severe kinds of irregular heart beat as well as rapid cardiac death (Kasper).
There are several types of Cardiomyopathy including dilated cardiomyopathy, hypertrophic, restrictive, arrhythmogenic right ventricular dysplasia, among others. Dilated cardiomyopathy is the commonest type of cardiomyopathy that, in most cases, affects grownups between the ages of ...

Oxygen is essential to the survival of all body cells. The supply of oxygen to those cells is maintained via the circulatory system. The circulatory system is an integral part of the cardiovascular system which is maintained by the heart, blood vessels and blood. The three main subtypes of circulatory systems that occur in humans are the systemic circulation, pulmonary circulation and coronary circulation. All the three types of circulation are dependent on one another to maintain the supply of oxygen to and removal of carbon dioxide from the body tissues.

Pulmonary circulation serves as the link between the ...

Kangaroo Mother Care: The Benefits of Skin-to-Skin Contact with Newborns

Kangaroo Mother Care, or Skin-to-Skin contact with a newborn immediately after birth, has proven to be a highly beneficial practice, with hardly any negative impact. Kangaroo Mother Care, or KMC for short, provides a newborn the warmth, stimulation, safety, protection from infection, and love that they need. KMC has benefits for not only the newborn, but also significant benefits for the mother, including a boost in her self esteem. Through various studies, pediatricians and obstetricians have found little negative impact through the use of the Kangaroo Mother Care method. The only time it should not be used is in emergency situations, where a newborn ...
