Coronary circulation Circulation of blood through the coronary blood vessels to deliver oxygen and nutrients to the heart muscle tissue Pulmonary circulation Circulation of the blood from the pulmonary artery through the vessels in the lungs and back to the heart via the pulmonary vein, providing for the exchange of gases Blood Pressure Terms Diastole To expand; period in the cardiac cycle when blood enters the relaxed ventricles from the atria Systole To contract; period in the cardiac when the heart Normotension Normal blood pressure Hypotension Low blood pressure Hypertension High blood pressure Symptomatic Terms Ateriosclerosis Thickening, loss of elasticity, and calcification of aterial walls Atherosclerosis Buildup of fatty substances that harden within the walls of arteries Atheromatous plaque A swollen area within the lining of an artery caused by buildup of lipids Thrombus A stationary blood clot Embolus
