GENERAL HISTOLOGY

Detailed explanation-1: -Net filtration pressure regulates the inward and outward movement of fluid at the ends of the capillary. The difference between blood and interstitial colloid osmotic pressures is the oncotic pressure. Oncotic pressure is the difference between the blood and interstitial colloid osmotic pressures.

Detailed explanation-2: -Osmotic pressure: Osmotic pressure is the pressure exerted to prevent the movement of free solvent molecules across a semi-permeable membrane into a region of high solute concentration. Oncotic pressure: Oncotic pressure is the pressure exerted by colloidal plasma proteins to reabsorb water back into the blood system.
