Explanation:

Detailed explanation-1: -Arteries and veins go into and out of the heart. Arteries carry blood away from the heart and veins carry blood to the heart. The flow of blood through the vessels and chambers of the heart is controlled by valves.

Detailed explanation-2: -Veins. Veins carry blood toward the heart. After blood passes through the capillaries, it enters the smallest veins, called venules. From the venules, it flows into progressively larger and larger veins until it reaches the heart.

Detailed explanation-3: -vein. Arteries are blood vessels responsible for carrying oxygen-rich blood away from the heart to the body. Veins are blood vessels that carry blood low in oxygen from the body back to the heart for reoxygenation.

Detailed explanation-4: -All veins are carried deoxygenated blood except the pulmonary vein which carries oxygenated blood from the lungs to the left atrium of the heart. Small vessels are called venules that continue from capillaries, merge to form veins, and drain the blood from capillaries into veins.
