The vascular system is a complex network transporting blood to and from all parts of the body. It distributes oxygenated and nutrient-rich blood to body tissue via arteries, arterioles, metarterioles, and capillaries. Venules and veins carry deoxygenated blood, cellular wastes, and carbon dioxide to the heart and lungs to be oxygenated or removed. The lymphatic system removes fluid left at the venous end of the capillaries and returns it to the circulatory system by way of the lymphatic ducts. Understanding the vascular system is basic to providing quality nursing care.
