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 ...

Summarize the role of each of the 12 human body systems.

Skeletal System: The role of the skeletal system is to provide a framework to give support and act as a defense for the soft tissues within the human body.

Muscular System: The role of the muscular system is to be accountable for all movement within the human body.

Cardiovascular System: The role of the cardiovascular system is to be accountable for the movement of nutrients, oxygen, hormones, and cellular waste products all over different parts of the body. Digestive System: The role of the digestive system is to transform food into energy and basic vitamins to nourish the whole human body. Endocrine System: The role of the endocrine system is to regulate the activities of all of the ...

Problem statement for research purpose: Hypertension can be a cause as well as a consequence of chronic kidney disease (CRD). A number of clinical studies have identified the harmful effects of uncontrolled hypertension on the kidney function (Kokubo, 2012; Berlowitz, 2016)). According to NIH statistics, 23.3% individuals without CKD had hypertension in a representative sample. On the other hand, 35.8% of individuals in stage 1, 48.1% in stage 2, 59.9% of stage 3 and 84.1% in stage 4-5 CKD had hypertension (National Institutes of Health, 2010). In stage 4 CKD, the glomerular filtration is the lowest at <15 ...

The cardiovascular system consists of blood, the heart, and the circulatory system, which includes veins, arteries, and capillaries. The function of these organs is to transport oxygen from the lungs to cells throughout the body. Each organ system in the body is essential in providing homeostasis in the human body. However, the actions of the cardiovascular system are critical to human life. Many physicians, scientists, and other professionals dedicate their life to the understanding of the cardiovascular system and its diseases so that people can live longer and more productive lives. This paper will discuss the general anatomy of ...

A Proper understanding of the pathophysiology of diseases and conditions is essential in their treatment as well as management. Every disease has a way of affecting the normal functioning of the body. Some disorders attack the whole body while others affect specific organs. Therefore, it is crucial to study the pathophysiology of diseases. It is also essential to understand the relationship between related diseases. This helps in understanding the interactions between the diseases. This paper is set to examine the pathophysiology of pneumonia, hypoxemia, as well as thyroid cancer. Additionally, the paper analyses the relationship between these diseases.

Pathophysiology of Pneumonia

Diabetes in its generality is a condition that is associated with elevated blood sugar levels. When these elevations persist, the patient may experience cases of disturbance of other body systems and leading to poor functionality and ultimately a chronic condition that affects their quality of life. Type-2 diabetes (T2DM) is the most common type of diabetes whose impact on the health of populations has significantly been documented (Murrock, Taylor & Marino, 2013). Apparently, among the documented aspects of health disparities, T2DM is noted as one of the biggest health challenges for African Americans. The prevalence is even higher among women ...

Introduction

This paper aims at evaluating concepts of alteration in homeostatic state, secondary to temporal variables. It analyses the case study of Brad, a 45-year old coal cutter who has held the job for 25 years. Brad is experiencing a chronic cough due to prolonged exposure to coal. Importantly, he has not been attending yearly checkups because he fears that his lung is “black.” The disease leads to fibrosis, reduced diffusing ability, and dilation of the small airways. In the final stage, the airways, alveoli, and pulmonary capillaries become damaged.

How the disease described in the case study creates incongruous between ventilation and perfusion

Chronic lung disease may induce mismatch in ventilation and perfusion ...

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 ...

Coursename 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 ...

Hypothalamus 1. What is the molecular mechanism to release TRH? TRH refers to the thyrotropin-releasing hormone. This hormone is produced by the hypothalamus. Before the full activity of TRH, some tightly controlled processes occur in the body including the appropriate folding of prohormone to move to the secretary pathway, the processing after translation, and movement of the peptides, which are processed, towards the secretary granules for secretion (Nillni n.p.). TRH develops from bigger inactive precursor (known as proTRH) as a result of modifications after translation and moved through the controlled secretary pathway. Prohormone convertases (abbreviated as PCs) including PC1/3 ...

Question 1. Insect-eating birds will decrease in number since their source of food has been reduced. The birds may also migrate to warmer areas during this period.

Question 2.

The habitat is the specific place where the organism lives e.g. a fish’s habitat is water. On the other hand, niche is the position and the role played by the organism in an ecosystem. It includes how the organism obtain food and shelter, the mode of survival, and the mode of reproduction (Sutton & Anderson, 2009, p. 46). For instance, a lion’s niche in the ecosystem is that of a predator.Question ...

1. Balance Diet and Physical Activity against Obesity and Hypertension The most essential way to prevent hypertension for those who are prone to obesity, and certainly for obese people - is the fight against excess weight. When we reduce the body mass by 1 kilogram - blood pressure decreases by 1 millimeter of mercury regardless of the original pressure level. There are only two ways to lose weight: a diet regime and an increased physical activity. But it is important to immediately warn against fasting that is very dangerous for health. It is possible only under the supervision of ...

Introduction

Pulmonary edema (PE) is characterized by the accumulation of fluid in the parenchyma and air spaces of the lungs. Most often PE is associated with respiratory failure and impaired gas exchange. Globally, PE is known to be characterized by two major factors, the first is associated with the injury of the lung parenchyma which is termed as non-cardiogenic pulmonary edema. The second is associated with the failure of the left ventricle of the heart to release blood from the pulmonary circulation within the system and is termed as cardiogenic pulmonary edema (Glaus, Schellenberg , and Lang. 2010). The major cause ...
