Pulmonary circulation moves blood between the heart and the lungs. It transports deoxygenated blood to the lungs to absorb oxygen and release carbon dioxide. The oxygenated blood then flows back to the heart. Systemic circulation moves blood between the heart and the rest of the body.

The amount of flow through the capillaries appears to be regulated to maintain adequate tissue oxygenation. The regulation of blood flow appears to be accomplished by the coordination of several different mechanisms which affect the flow of blood through precapillary vessels.
13 lis 2022 · Oxygen is transported in the blood in two ways: Dissolved in the blood (1.5%) Bound to haemoglobin (98.5%) Bound to Haemoglobin. Once oxygen has entered the blood from the lungs, it can be bound by haemoglobin (Hb) in the red blood cells. Haemoglobin is a protein comprised of four subunits: two alpha subunits and two beta subunits.
21 lis 2023 · The blood circulatory system (cardiovascular system) delivers nutrients and oxygen to all cells in the body. It consists of the heart and the blood vessels running through the entire body. The arteries carry blood away from the heart; the veins carry it back to the heart.
10 lis 2020 · Oxygen enters the bloodstream via the lungs, where it diffuses across the alveolar epithelium and pulmonary capillary endothelium to reach the pulmonary circulation. Once the oxygen has entered the pulmonary circulation, it is carried in the blood to target tissues in two distinct forms: Bound to haemoglobin (around 98% of total blood oxygen ...
8 lis 2023 · Blood flows through your heart, lungs and body in a series of steps. It delivers oxygen and nutrients to all your organs and tissues and removes waste.
14 lis 2022 · Oxygenated blood returns to the heart and is distributed throughout the body by way of the systemic vasculature. Oxygen is carried in the blood in two forms. Most oxygen in the blood is bound to hemoglobin within red blood cells, while a small amount of oxygen is physically dissolved in the plasma.
