blood pressure
force exerted by blood on the walls of ateries
bradycardia
abnormally slow heart rate below 60 beats per minutes

CHF- cannot pump blood to other organs
coronary arteries
crown of artery that supply blood with fresh oxygen blood
coronary heart disease
blockage of arteries that supply the heart muscle
cor pulmonale
heart disease that causes right ventricle to enlarge
cyanosis
bluish discoloration of skin due to lack of oxygen
diastole
cardiac cycle where both atria and venctricles are relaxed
