Blood vessel

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 triphosphate (ATP) to support the continued contraction of the muscles. During this time CO2 is expelled though the heart pumping deoxygenated blood to the…

heart attacks because of high blood pressure, smoking, diabetes, and abnormal cholesterol levels. Furthermore, a study conducted by Hambrecht et al. (2000) was to determine if aerobic exercise training can improve coronary reserve in patients with coronary artery disease and endothelial disfunction. Vascular endothelium plays a major role as modulator in the synthesizing and releasing of nitric oxide. A modulator is a factor…

the blood, vessels, and tissue not functioning properly. Intravascular hydrostatic forces and interstitial osmotic forces will move fluid in and out of the blood vessels. Opposite to this is the osmotic pressure which pushes or pulls fluid in and out of vessels.…

The circulatory system is composed of vessels that take blood from the heart, thin-walled capillaries where exchange occurs, and vessels that return blood to the heart. Blood is pumped by the heart simultaneously into two ways the pulmonary and systemic circuits. The pulmonary system takes blood through the lungs where gas exchange occurs and the systemic system transports blood to all parts of the body where exchange with tissue fluid takes place. In practical terms, we can think of the…

the tunica intima is equipped with pockets that act as one-way valves. These valves prevent the back flow of blood and allow the veins to act as supplemental pumps that help to keep the blood following in one direction, back toward the heart. The activity of the skeletal muscle that surround the veins will create the pressure that derives the venous pump. 2- Functions; - and oxygen the blood in the capillaries into the interstitial flued and then into the cells. Carbone dioxide and other…

cardiovascular system Blood vessels Arteries, veins and capillaries takes blood and nutrition to the muscles and back from the heart. Arteries take the blood that has O2 in it away from the heart under high pressure with a small diameter and it has thick muscular walls, and veins take the blood back to the heart under low pressure it has a medium thickness to it and a large diameter because it has valves to stop the blood flowing backwards. Capillaries is one cell thick so it can take the…

disease refers to a range of diseases that affect the heart and the blood vessels. Among the common ones are heart attacks – blockage of the blood flow to a part of the heart, and ischemic stroke –blockage of a blood vessel that feeds a part of the brain. Other types of cardiovascular disease include heart failure, arrhythmia and heart valves problems. This paper…

2 Part A Cebita Santhosh Q1. The three main types of blood vessels in the circulatory system are veins, arteries and capillaries. The veins carry deoxygenated blood from the capillaries back to the heart. The arteries carry blood away from the heart to your tissues. The capillaries are the smallest of the body's blood vessels, only one cell thick and are found in the muscles and lungs. Q2. Eating too much salt can raise your blood pressure because of the extra water stored in the body.…

when the blood supply to part of your brain is interrupted or severely reduced, depriving brain tissue of oxygen and nutrients”(Mayo Clinic Staff). “Within an hour, the nerve cells in that area of the brain become damaged and die. As a result, the part of the body controlled by the damaged area of the brain cannot work properly” (“Stroke”). Therefore, this leads to the different types of strokes, which are Acute Ischemic stroke and Hemorrhagic stroke. “ In an ischemic stroke, the blood supply to…

transport materials around the body with blood serving as its transport medium. Blood is contained and transported in hollow tubes known as blood vessels. The body has three main types: Arteries, capillaries and Veins. All arteries (with the exception of pulmonary and umbilical arteries) transport Oxygenated blood away from the heart to the rest of the body. They branch off into smaller structures named arterioles which lead to the Capillaries. In the capillaries the blood exchanges materials…
