Kärlsystemets

Kärlsystemets, often translated as the vascular system, refers to the network of blood vessels in the body responsible for transporting blood. This intricate system includes arteries, veins, and capillaries, all working in concert to deliver oxygen and nutrients to tissues and remove waste products. Arteries carry oxygenated blood away from the heart, branching into smaller arterioles and then into the microscopic capillaries. These capillaries are the sites of crucial exchange, where oxygen and nutrients diffuse into cells, and carbon dioxide and other waste materials are picked up. From the capillaries, deoxygenated blood flows into venules and then into larger veins, which return the blood to the heart. The heart itself acts as the central pump, propelling blood through the entire circulatory network. The health and proper functioning of the kärlsystemets are vital for maintaining overall bodily health, with disruptions leading to various cardiovascular diseases.
