Question 15

Explain why describing vessels as a “plumbing system” is physiologically inaccurate.

Answer 15

A plumbing system is static and the vessels are dynamic. More like baloons that can expand and constrict.

Question 16

State the names, location, and function of the 3 vessel layers.

Answer 16

Innermost = tunica intima (simple squamous endothelium)
-continous with linings of the heart
-smooth surface allows blood to flow without
friction
Middle: Tunica Media (made of smooth muscle regulated by nerve fibers of autonomic system and elastin
-contracts and expands to control blood flow
and blood pressure
-smaller diameter= harder to pass
Outer: Tunica Externa (loosely woven colagen fiber)
-protection and reinforcement
