Blood Flow:

Parts of the Cardiovascular System: Arteries—take blood AWAY from the heart (oxygen-rich blood) Veins—take blood TO the heart (oxygen-poor blood) Capillaries—tiny passageways that allows exchanges of nutrients and oxygen between body cells and blood

Types of Circulation: Pulmonary—heart to lungs to heart Systemic—heart to body to heart
