Answers
cappilaries:-Capillaries, the smallest and most numerous of the blood vessels, form the connection between the vessels that carry blood away from the heart (arteries) and the vessels that return blood to the heart (veins). The primary function of capillaries is the exchange of materials between the blood and tissue cells.
heart:-Blood carries oxygen and other important nutrients that all body organs need to stay healthy and to work properly. Your heart is a muscle, and its job is to pump blood throughout your circulatory system.
vein:-Veins are vessels of the circulatory system
that support circulation by conveying blood to the heart. Blood flowing through the circulatory system transports nutrients, oxygen, and water to cells throughout the body.
artery:-Arteries carry blood away from the heart. Pulmonary arteries transport blood that has a low oxygen content from the right ventricle to the lungs. Systemic arteries transport oxygenated blood from the left ventricle to the body tissues.
