BLOOD VESSELS

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
The pressure of blood inside the capillary forces water out of the blood and into the interstitial spaces. This force is called:
A
hydrostatic pressure
B
osmotic pressure
C
Either A or B
D
None of the above
Explanation: 

Detailed explanation-1: -Oncotic or colloid osmotic pressure is a form of osmotic pressure exerted by proteins in the blood plasma or interstitial fluid. Hydrostatic pressure is the force generated by the pressure of fluid within or outside of capillary on the capillary wall.

Detailed explanation-2: -The hydrostatic pressure is a factor of systemic perfusion of the capillary, the arterial and venous pressures, and the change in resistance across the capillary. Oncotic pressure is due to plasma proteins (namely albumin) that do not readily cross the capillary membrane.
