APHY 102 Blood Vessels Ivy Tech Exam Guide
2026 Questions Set
1. take blood away from the heart; oxygenated except for Artery
pulmonary circulation and umbilical vessels of fetus
(a)
2. return blood to the heart. Most blood in the body is vein
found in these vessels.
(b)
3. connect the arteries to the veins; the site of nutri- capillary
ent, gas, and waste exchange between the circulating
blood and body tissues
4. the space that contains the moving blood lumen of blood vessels
5. inner layer of blood vessels; endothelium tunica intima
, APHY 102 Blood Vessels Ivy Tech Exam Guide
2026 Questions Set
6. middle layer of blood vessel; smooth muscle layer tunica media
7. outer layer of the blood vessel; consists of collagen tunica adventitia (externa)
fiber connective tissue
8. a network of small blood vessels that supply the walls vasa vasorum
of large blood vessels, such as elastic arteries (aorta)
and large veins (vena cava).
9. elastic, muscular, arterioles what are the 3 types of ar-
teries?
10. aka conducting arteries. Large thick-walled arteries elastic arteries
with elastin in all three tunics. Ex: Aorta and its major
branches. Act as pressure reservoir.

11. expand and recoil as blood ejected from heart. Proper- pressure reservoir
ty of arteries due to elastic tissue.
12. aka distribution arteries. Deliver blood to body organs. muscular arteries
Ex: brachial and splenic arteries. Thick tunica media
with more smooth muscle.
13. Smallest arteries. Lead to capillary beds. Control flow arterioles
into capillary beds. Used to control blood pressure via
vasodilation (lowers BP) and vasoconstriction (raises
BP). (1)
14. contains only tunica interna (simple squamous (en- structure of capillaries
dothelia) + basement membrane)
15. controls blood flow through capillary beds (controlled pre-capillary sphincters
by sympathetic nerves). 75% of capillaries are closed
at a given time. Regulated by local chemical conditions
and vasomotor nerves.
16. large veins (superior and inferior vena cava), medi- types of veins
um-sized veins, small veins, venules
17. venule
