Microcirculation

Question 1

Vaso Vasorum

Answer 1

tiny vessels to supply blood to the tissue of large blood vessels

Question 2

Tunica Adventiita

Answer 2

Outermost layer of structural college

Question 3

Tunic Media

Answer 3

Middle layer with an external elastic membrane and smooth muscle membrane

Question 4

Tunica Intima

Answer 4

Innermost layer with internal elastic membrane, lamina propia (smooth muscle+connective tissue), base membrane, and endothelial cells

Question 5

Precapillary Sphincters

Answer 5

smooth muscle around capillaries which control blood flow, dilates in respnose to highly metabolic tissue which has increased O2 demand

Question 6

Thoroughfare Channel

Answer 6

capillaries without precapillary sphincters, pathway direclty from metarterioles to venules

Question 7

CHP

Answer 7

Capillary Hydrostatic Pressure

• pressure that the capillary blood places on the capillary wall which favors filtration
• inc w/BP, HF

Question 8

Neg IFP

Answer 8

Negative Interstitial Fluid Pressure

-negative pressure in the interstitium created by sucking of the lympatic system

Question 9

PCOP

Answer 9

Plasma Colloid Osmotic Pressure

-determined by proteins in the blood (mostly albumin) aka Oncotic pressure, favors reabsorption

Question 10

IFCOP

Answer 10

Interstitial Fluid Colloid Osmotic Pressure

-colloids in the interstitium which favor filtration into the interstitium
