Question

does anyone know the forces at work in arterial end and venous side of a capillary bed?

also the organs/proteins responsible for hydrostatic pressure and blood osmotic pressure

Answer 1

the forces at work are capillary hydrostatic and oncotic pressures, as well as interstitial hydrostatic and oncotic pressures.

hydrostatic pressure is due to the pumping pf the heart. Osmotic pressure is due to the protein albumin in blood plasma.
