receives blood entering the heart
the chamber that pumps blood from the heart to the rest of the body
the pathway that blood follows from the heart to the lungs
Pulmonary Circulation
the route that blood travels from the heart to most of the body and then back to the heart
Systemic Circulation
a group of cells in the right atrium wall that helps regulate the rate at which the heart beats or contracts

largest artery in the body and part of the systemic circulation
carry blood to the heart muscle itself
Coronary Arteries
smaller blood vessels that branch off from arteries
the smallest blood vessels in the body

Rh factor
a buildup o cholesterol and other fatty materials on artery walls, which restricts the flow of blood
when the coronary arteries become clogged as a result of atherosclerosis
Coronary Heart Disease
a type of pain caused by a lack of oxygen
Agina Pectoris
when blood flow to part of the heart muscle is blocked
Heart Attack
when structural problems of the heart are present at birth
Congenital Heart Disorders
damages the valves of the heart
Rheumatic Heart Disease
blood pressure that is consistently higher than normal
a condition in which the blood flow to a part of the brain is suddenly cut off
a condition in which there are too few red blood cells or too little hemoglobin in the blood
a condition in which red blood cells curve into a sickle shape because of a flaw in the hemoglobin
