The above statement is FALSE. Blood from head and neck is carried back to heart by gravity. Movement of blood in veins through muscle contraction is achieved in legs and arms by the help of skeletal muscle pump. The skeletal muscles contracts and squeezes blood in the vein upwards, back to 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...
