What are the 3 types of Arteries and explain their significant characteristics.
Where are elastic arteries located?
How is arteriole BP regulated?
What are ARTERIES also known as?
1) Elastic arteries: high pressure tubes, expand to receive blood, when ventricles relax, they recoil and pump more.
Located: Pulmonary trunk and Aorta.
2) Muscular arteries: *most arteries, mid-sized, mostly tunica media w/ thick smooth muscle.
- 3) Arterioles: tiny vessels, mostly smooth muscle;
- -BP regulated by the DIAMETER of the vessel.
AKA: conducting arteries
