Term
Arteries
Definition
-Carry blood away from ventricles of heart and lead to capillaries

-carry blood away from heart under high pressure
Term
3 layers of arerial wall
Definition
Tunica interna: innermost; made of endothelium; rests on connective tissue

Tunica Media: middle layer; bulk; made of smooth muscle

Tunica externa: outermost; collagen-rich connective tissues; attaches artery to surrounding tissues
Term
Veins
Definition
-carry blood back to the atria of heart

-typically parallel the aterial system 

-have valves from the tunica interna; project inward to prevent blood back flow
Term
3 layers of venous walls
Definition
Tunica externa; outermost; connective tissue

Tunica media: middle layer; small amount of smooth muscle and elastic tissue

Tunic Interna: innermost; composed of endothelial cells; thin
Term
capillaries
Definition
-connections between arteries and veins

-serve as sites for exchange processes
Term
one cell layer of capillaries
Definition
endothelial cells comprising a simple squamous epithelium

-covered by basement membrane
