| Carrys blood away from the heart | artery |
| carry blood toward the heart | vein |
| known as echange vessels | capillaries |
| The wall of veins and arteries have three coats called | tunics |
| When several capillaries unite they form | venules |
| leaky venous valves are called | varicose veins |
| three ways that capillaries exchange materials is | diffusion, transcytosis and bulk flow |
| the pressure exerted by the blood on the walls of the vessels | blood pressure |
| opposition to blood flow due to friction between blood and walls of blood vessels | resistance |
| fainting not due to head trauma | syncope |
| the location of the cardiovascular center | medulla oblongata |
| the name for pressure sensitive recpetors in the aorta and internal carotid | baroreceptors |
| sensory receptors that monitor the chemical composition of blood | chemoreceptors |
| RAA | renin angiotensin aldosterone pathway (Increase blood pressure) |
| blood flows through two capillary networks before going back to the heart | portal system (hepatic) |
| after blood flows through arteries it enters | arterioles |
| after blood flows through venules it enters | veins |
| after blood flows through capillaries it enters | venules |
| the two main types of arteries are | muscular and elastic |
