the bottom of the heart. Blood flows into the right atrium‚ passes through the tricuspid valve‚ and makes its way into the right ventricle. It then moves through the pulmonic valve‚ into the pulmonary artery to the lungs.” After picking up oxygen in the lungs‚ the blood moves out of the lungs into the pulmonary vein‚ into the left atrium‚ through the mitral valve‚ and into the left ventricle that pushes blood to the body through the aortic valve. Once blood leaves the heart it is in the aorta where
Premium Heart Blood Blood vessel
blood vessels and structure There are three types of blood vessel‚ Arteries ‚ veins and capillaries. Each of them have different functions involved in carrying blood around the body . Arteries are blood vessels that transport blood away from the heart‚ veins are blood vessels that transport blood to the heart and Capillaries are extremely small vessels located within the tissues of the body that transport blood from the arteries to the veins. they must be constructed for carrying fluids over long

structures involved in these important task are blood vessels‚ which form a closed system of tubes that carries blood away from the heart‚ transports it to the tissues of the body‚ and then treturns to the heart. The five main types of blood vessels are arteries‚ arterioles‚ capillaries‚ venules‚ and

Blood fails to get out to other parts of the body as quickly as it returns from the lungs. When blood doesn’t get back to the heart‚ it backs up in the lungs blood vessels. Blood is then forced into the intracellular space in the lungs causing pulmonary edema. (Cadwallader pp. 1141 - 1142). Right-sided heart failure results from the inability of the right ventricle to function properly. Blood isn’t pumped to the lungs as quickly as it returns from the other parts of the body. Fluid then begins
Premium Heart Hypertension Myocardial infarction
AbstractBackground pulmonary arterial hypertension (PAH) and chronic thromboembolic pulmonary hypertension (CTEPH) are fatal‚ no curable‚ but treatable diseases that strongly affect the patients. Objective. To decribe patient’s experience of information relating to PAH or CTEPH. Methods. A qualitative method using content analysis was applied. Seventeen patients (thirteen women an four men) aged 28-73 years from a regional PAH center were individually interviewed. Results. Three categories that
Premium Medicine Patient Illness
Cardiovascular diseases include a wide range of heart abnormalities‚ as well as diseases of other parts of the circulatory system‚ such as the coronary arteries‚ ther cerebrovascular system‚ the aorta and pulmonary vessels‚ and the peripheral arteries and veins. Abnormalities of these structures may be either congenital or acquired over time. It has been said that cardiovascular disease kills about 954‚000 people annually‚ including more than 156‚000 people under the age of sixty-five years.

The Pathology of Myocardial Infarction The heart is considered one of the most vital organs for human survival and is responsible for giving human life and pumping blood through the arteries‚ capillaries‚ and veins. Heart diseases make the heart function improperly which causes the blood to not circulate throughout the body‚ making human life impossible. Heart diseases is considered to be number one on the top ten lists of death in the world. Because of this reason‚ I believe that understanding

to push the blood to our head and feet continuously. Circulation is the blood flow around our bodies. The heart connects the two major portions of the circulation’s continuous circuit‚ the systemic circulation and the pulmonary circulation. The blood vessels in the pulmonary circulation carry the blood through the lungs where the gasses oxygen and carbon dioxide are exchanged. While the blood vessels in the systemic circulation carry the blood throughout the rest of our body (Martini & Bartholomew

back flowing into the right atrium. As the right ventricle contracts‚ the blood travels through the pulmonic valve and leaves the heart. Through the valve‚ the blood travels to the pulmonary artery and into the lungs‚ which is where the blood will be oxygenated. Once filled with oxygen‚ the blood travels through the pulmonary veins and goes into the left atrium. Once the oxygen filled blood is deposited into the left atrium‚ it begins to contract‚ which ultimately causes it to move into the left ventricle
