Heart valve

everything they need, the heart needs to be beating. The cardiovascular system makes sure the levels of substances in the blood is constant by transporting these substances as circumstances change. The heart is located in the lower part of the mediastinum between the lungs. Most people think the heart lies on the left side of the body but if the chest was cut in half, two thirds of the heart would be on the left and one third would actually be on the right side of the body. The heart is…

TASK 1 HEART The heart is a muscular organ that pumps blood throughout the body (Chiras, 2008). STRUCTURE The heart wall is composed of three layers of tissues: pericardium, myocardium and endocardium (Wilson, Waugh and Ross, 1996). Label structures of the heart for the diagram. Aorta is the major artery that carries oxygenated blood to the body. Pulmonary veins carry oxygenated blood from the lungs into the heart. Left atrium is one of the left upper chambers that takes oxygenated blood from…

left side of the heart? of the heart valves? The function of the septum is to separate the two sides of the heart. The left side of the heart takes in oxygen rich blood, the the valves prevents back flow of blood to the heart. 2. What is the function of the right side of the heart? the function of the right side of the heart is to pump deoxygenated blood into the pulmonary veins around the lungs. 3. What are the major blood vessels that bring blood into the right side of the heart? out of the…

Every minute, the heart pumps about 1.5 gallons of blood through the body. The heart is “just above the diaphragm, between the right and left lungs” (Balaban 197). About two-thirds of the heart are located on the left side of the chest, while only about one-third of the heart is located on the right side of the ribcage. The cardiovascular system provides a transport system between the heart and lungs. The heart’s most important function is to indulge indispensable nutrients to the tissues and to…

Rheumatic heart disease is when the heart is damaged. It’s often damage to the valves of the heart. Rheumatic heart disease is a result of having rheumatic fever. It’s commonly seen in children in many developing countries around the world. To begin with, Rheumatic fever causes a person to have rheumatic heart disease. Rheumatic fever affects the connective tissues of the body, mostly the connective tissues of the heart, brain and the joints of the body. Rheumatic fever is associated with having…

Venous return is the flow of blood back to the heart. This process is achieved by five mechanisms. The Pressure Gradient, now this mechanisms work via the heart generating pressure even though the pressure is weaker in the veins than in the arteries it is still the most important force in the venous flow. Gravity, but only when you are sitting or standing anywhere above the heart simple gravity is at work in returning blood back to the heart, not to say that very thing isn’t still working…

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 blood to and from…

(auscultating) Caleb’s heart. a. Where on the thoracic surface do you auscultate to the tricuspid, mitral (bicuspid), pulmonary, and aortic valves? The tricuspid valve is between the right atria and right ventricle. Therefore, you would auscultate the tricuspid valve on the left side of the heart, between the fourth and fifth rib (or intercostal space) and lower left sternum area. The mitral valve is between the left atrium and left ventricle. Therefore, you would auscultate the mitral valve on…

Assessing Heart and Neck Vessels Physiology Blood usually flows through the heart silently, but when there is a swooshing or blowing sound heard upon auscultation it is referred to as turbulent blood flow (Weber & Kelley, 2014). This occurs in a variety of conditions such as increased blood velocity, structural valve defects, valve malfunctions, and abnormal chamber openings (Weber & Kelley, 2014). The heart has four chambers two atria, which are the upper chambers of the heart and two…

The congenital heart defect Tetralogy of Fallot (TOF) while uncommon is treatable and will allow patients to live semi-normal lives. The most important part is early diagnosis so that treatment can be done in an orderly manner. While this is a disease that someone is born with it evolves into a chronic health threat requires constant observation and treatment. It is best managed most effectively by a group of Pediatric Cardiologists. Most children are treated by a team of Pediatric…
