6-7 Orbital Vasculature

Question 1

What distinguishes an artery, vein, and capillary from one another?

What’s a pericyte?

Answer 1

Arteries= oxygenated blood away from heart
Vein= deoxygenated blood too the heart. 
Capillaries= fusion. Metabolic waste out, macronutrients in, very thin walled. 

Pericytes help to dilate and constrict the capillaries.
