up to 30 feet into the air

2.  Pumps 7,000 liters of blood through the body each day

lifetime
 This muscular pump forces blood through arteries,
which connect to smaller-diameter vessels arterioles.

7.  Pericardium – encloses the heart
 Parietal Pericardium – covers the wall of the
pericardial cavity
 Pericardial Cavity – a space that contain a small
volume of serous fluid that reduces friction between
the pericardial membranes
 Visceral Pericardium (epicardium) – covers the heart

17.  Hypertension
 Myocardial Infarction
 Myocardial Hyperthrophy
 Aneurysm
 Atrial/Ventral Septal Defect
