Why is it important? Your body’s cells depend on the blood vessels to bring nutrients & remove wastes.
Just like water moving through pipes, materials are moved throughout the body by the cardiovascular system. Cardiovascular system includes your heart, kilometers of blood vessels, and blood.
Your heart is an organ made up of __________ muscle tissue. Four Compartments called chambers Two upper chambers are called atriums Two lower chambers are called right and left ventricles
Coronary circulation: the flow of blood to and from the tissues of the heart. When coronary circulation is blocked, oxygen and nutrients cannot reach the cells of the heart and a heart attack occurs!
Pulmonary circulation: the flow of blood through the heart to the lungs and back.
Systemic circulation: the flow of blood to the rest of the body (NOT the lungs or heart)
Carry blood to every part of your body Blood moves oxygen and nutrients to cells. Blood moves waste and carbon dioxide away from cells.
Blood only flows one direction in each vein. A valve prevents blood from flowing in the wrong direction through a vein.
