C.S. HEART • Theheartis a muscle in thechest. • Itcontracts to pump blood.
C.S. • HEART
C.S. • What side is left?
C.S. • What is the other side?

BLOOD CIRCULATION: C.S.
C.S. • from the body
C.S. • from the atrium to the ventricle
C.S. • from the ventricle to the artery (aorta) and to the body
C.S. • from the atrium to the ventricle
C.S. • from the ventricle to the artery and to the lungs
C.S. • Why does the blood move only in one direction ?
C.S. THERE ARE VALVES: between the atrium and ventricle and between the ventricle and artery
