Blood pumps from the heart into the great arteries. From here it flows into the finer arterioles, then the capillaries, where exchange of gases and other susbtances with the the tissues take place. From here, the blood flows into venules, then to the veins, and returns back to the heart.

Blood Vessels and the Circulatory System Overview of Circulatory System Blood vessels form closed tubular systems which carry blood from the heart through the systemic and pulmonary systems. Arteries carry blood away from the heart to smaller arterioles, which feed capillary beds. The capillary beds empty into venules, which coalesce into larger veins. All veins eventually empty into the superior and inferior venae cavae or into the pulmonary veins. These vessels return blood to the heart. A. List the heart...
