Circulatory system

Sickle cell is a disease that affects the circulatory system. The circulatory system is in charge of moving nutrients throughout the entire body with the use of the blood stream. According to hopkinsmedicine.org the circulatory system moves nutrients, water, and oxygen to the your billions of body cells and carries away wastes like; carbon dioxide that body cells create. The circulatory system includes; the heart: which keeps the circulatory system working at all times with its constant…

Normally, as the heart contracts, it is able to exert a pressure that drives blood throughout the cardiovascular system and allows for perfusion as well as gas and nutrient exchange to take place. This blood flow is typically described by the equation Q=P/R, where Q represents blood flow, P is the pressure gradient, and R stands for total peripheral resistance.1 In a well-functioning system, a general balance is maintained between the pressure and resistance, which allows blood to reach all…

CASE STUDY 1 1. The cardiovascular system consists of the following- Blood – It is a red color fluid in the body. Heart – It is also called the control center of our body. It pumps and collects blood to and from the various parts of our body. Blood vessels – Blood vessels are path through which transport medium circulates in our body. 2. The functions of cardiovascular system are as follows- Transportation- It transports blood to all the parts of body. The blood delivers oxygen and nutrients…

Decanters often intimidate the average wine drinker. In fact, most people don't even have a decanter in their home. For those who enjoy red wine everyday, it is important to understand the role a quality decanter can have on your wine experience. Not all red wines need to be decanted. In fact, most table wines don't need the added step of using a decanter. But, when you want to enjoy a quality aged big bold red wine, a decanter will help it open up. This will shape your overall experience.…

The article, Mass Transport in an Anatomically Realistic Human Right Coronary Artery, written by M.R Kaazempur-Mofrad and C.R. Ethier, analyzes mass transport patterns in a realistic right coronary artery model and looks at what affects mass transport from blood to the wall of the artery. The researchers were looking for any relationships between atherosclerosis, a disease of the arteries characterized by built up plaque on their inner walls, and hemodynamic and mass transport patterns. To…

Cardiovascular health refers to the health of the heart and the blood vessels. It is important to have proper blood supply to various organs in the body to support good health. The heart is a muscle that actually pumps blood throughout the body. Other organs in the body definitely become affected if there is something wrong with the heart (“Cardiovascular disease,” 2012). Obviously, if the heart muscle fails to function completely, then you die. This is because there will be no more blood flow…

and has a general knowledge of the entire human body and the diseases that affect it. The PCP is trained to handle first encounters and provides continuing care for patients with any undiagnosed sign or symptom regardless of problem origin or organ system. PCPs may be general practitioners, family physicians, pediatricians, geriatricians, or gynecologists and work in a variety of settings (i.e. office, hospital, long-term care facility), providing patient education, disease prevention, diagnosis…

The heart is one of the major organs in the body that is essential. The heart is considered a pump that helps the blood flow, continuously, throughout the body. The heart is located under the rib cage, between the lungs, and more on the left side of the breastbone. It has two major coronary arteries, electrical impulses, four chambers, and four valves to help the blood flow one way. Deoxygenated blood enters the right atrium from the superior and inferior vena cava. When the right atrium…

called the isovolumic relaxation time, during this stage pressure decreases, no blood enters the ventricles, the ventricles then begin relaxing and the semilunar valves close due to pressure of blood found in the aorta. The heart also has a conduction system which allows a pulse to be generated by the sinoatrial node, which stimulated the cardiac muscle, aka the myocardium. The myocardium contracts while propagated which causes a rhythmic pulse in the cardiac…

Pathophysiological Effects (Cardiovascular Responses) of Excessive Exercise Abstract The cardiovascular system is a complex system that contains the heart, the blood as well as the vasculature. Its purpose is to receive oxygenated blood from the lungs and pumps the oxygenated blood to the rest of the body (organs and skeletal muscles). During exercise there is an increase in the supply of oxygen to the working muscles, this happens so that there is an increased generation of adenosine…
