Artery, veins and capillaries R. A R. V. Pulmonary Artery lungs pulmonary Vein –> L. A. Aorta

A is for ARTERY!! Structure: Structure Function: Function a) thick walls b) three layers of tissue. c) Strong and flexible to withstand high blood pressure pumped by the heart. d) High Pressure a) Carry Oxygen Rich blood AWAY from the heart b) Artery=Away c) Most carry oxygen rich blood, except the pulmonary artery carries oxygen poor blood to the lungs

C is for Capillary!! (Not Cookie!) Structure: Structure a) Thin wall b) ONE CELL THICK! Function: Function Artery Capillaries Vein a) material exchange between blood and body cells b) This process happens by (DIFFUSION!!!!) What substances diffuse between capillaries and the body

Structure: Structure V is for VEINS! a) three layers of tissue b) thinner than arteries. c) Contains valves: prevent the backflow of blood Function: Function a) returns blood back to the heart b) Low pressure c) Most carry oxygen poor blood, except for the pulmonary vein that carries oxygen rich blood from the lungs
