OBJECTIVES:Explain the function of the circulatory systemDescribe the function of each part of the circulatory system
Our CIRCULATORY SYSTEM is the transport system of the body. It is an intricate network of long, slender branches originating from the heart and running through the different parts of the body.
The HEART pumps and moves blood through the body
RIGHT ATRIUM receives deoxygenated blood
RIGHT VENTRICLE pumps blood to the lungs
LEFT ATRIUM receives oxygenated blood
BLOOD is the transport system
RED BLOOD CELL (Erythrocytes) deliver oxygen to the cells
WHITE BLOOD CELLS (leukocytes) fight germs that enter the body
PLATELETS (thrombocytes) are used in blood clotting
PLASMA is where blood cells are suspended
BLOOD VESSELS are tubes that carry blood to and from the heart
ARTERIES carry blood that contains nutrients and oxygen from the heart to the different parts of the body
VEINS carry blood back to the heart.CAPILLARIES carry oxygen and nutrients to the cells
