Blood vessels and circulation

is a topic related to the circulatory system. The circulatory system is responsible for transporting oxygen and nutrients to the body’s cells and organs, and for removing carbon dioxide and other waste products. The circulatory system is made up of a network of blood vessels, including arteries, veins, and capillaries. Arteries carry oxygenated blood away from the heart and towards the body’s cells and organs. Veins carry deoxygenated blood back to the heart. Capillaries are the smallest blood vessels and are responsible for exchanging oxygen and nutrients between the blood and the body’s cells and tissues.
