Blood Vessels
Closed system of tubes that conducts blood throughout body; consists of arteries, veins, and capillaries

Carbon Dioxide
Waste product of cellular energy production; is removed from cells by blood and eliminated from body by lungs
Circulatory System
System that transports blood to all areas of body; organs of circulatory system include heart and blood vessels (arteries, veins, and capillaries); also called ‘cardiovascular system.’
Deoxygenated
Blood in veins that is low in oxygen content
Heart
Organ of cardiovascular system that contracts to pump blood through blood vessels
Oxygen
Gaseous element absorbed by blood from air sacs in lungs; necessary for cells to make energy
Oxygenated
Term for blood with a high oxygen level
Pulmonary Circulation
Transports deoxygenated blood from right side of heart to lungs where oxygen and carbon dioxide are exchanged; then it carries oxygenated blood back to left side of heart
Systemic Circulation
