What is a system circulation?
system circulation is part of the cardiovascular system in many complex organisms, including humans; He is responsible for the transfer of oxygenated blood from the heart to the rest of the body and deoxygenated blood from the rest of the body back to the heart. In the pulmonary circulation, this deoxygenated blood moves from the heart to the lungs, where it is oxygenated before returning to the heart. These two main components of the cardiovascular system are responsible for providing the whole body with oxygen and important nutrients that are transmitted by blood. Blood from the systemic circulatory system also passes through the kidneys where the blood is filtered from the blood.
different types of blood vessels known as arteries, arterioles, capillaries, veins and coronary vessels are involved in the system of systemic circulation. Blood is first pumped from the left ventricle of the heart to a large artery known as aorta. Aorta Tslepice branches to many other main arteries that supply blood to cells in the upper and lower body parts. The main arteries continue to branch into smaller arteries called arterioles. These mnOho branches arteriol will eventually end into capillaries.
Thecapillaries are the smallest and largest of the blood vessels in the systemic circulation and are the most direct into the process of actually supplying blood to the cells that need it. The capillaries form a branched structure similar to a website known as a "capillary bed" in any given area of the tissue. These capillary beds are responsible for maintaining well -supplied organs with oxygen and nutrients and for collecting waste from nearby tissues. The wide scattered capillary beds eventually combine at their ends and spread to venules, allowing blood to flow from capillaries to veins.
Blood from veins is to taste oxygen and bears a number of cell waste products. This blood is transferred back to the heart and closes the systemic circulation. The blood then moves to the lungs for oxygenation through the lung circulation, so it can be reused for systemic circulation.
the heart itselfIt must also receive a constant supply of oxygen and nutrients from the system circulation system to work. However, it does not receive them through the process of supplying the rest of the body with blood. The distinct part of the system circulatory system known as coronary circulation is responsible for providing the heart a stable blood supply. Coronary circulation occurs as a small loop in systemic circulation, which carries blood only from the heart back to the heart.
