kärlflöde

Kärlflöde refers to the flow of blood through the blood vessels of the body. This continuous circulation is essential for delivering oxygen and nutrients to all tissues and organs, as well as for removing waste products like carbon dioxide. The circulatory system, comprising arteries, veins, and capillaries, is driven by the heart's pumping action. Arteries carry oxygenated blood away from the heart, branching into smaller arterioles and then into a dense network of capillaries where the exchange of substances occurs with the surrounding cells. Deoxygenated blood then returns to the heart through venules, which merge into larger veins. The rate and pressure of kärlflöde are influenced by various factors, including heart rate, blood volume, and the elasticity of blood vessel walls. Maintaining healthy kärlflöde is crucial for overall health, and disruptions can lead to various cardiovascular conditions.
