Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Considering the bulk flow that occurs at capillary beds, the lymphatic system is needed to
A
reabsorb excess fluid from the interstitial fluid.
B
filter additional lymphatic fluid into the interstitial fluid.
C
connect arterioles to venules and provide a shunt from the true capillaries.
D
regulate colloid osmotic pressure so that filtration levels do not decline.
Explanation: 

Detailed explanation-1: -Bulk flow is used by small, lipid-insoluble solutes in water to cross the the capillary wall. The movement of materials across the wall is dependent on pressure and is bi-directional depending on the net filtration pressure derived from the four Starling forces that modulate capillary dynamics.

Detailed explanation-2: -The net pressure that drives reabsorption-the movement of fluid from the interstitial fluid back into the capillaries-is called osmotic pressure (sometimes referred to as oncotic pressure). Whereas hydrostatic pressure forces fluid out of the capillary, osmotic pressure draws fluid back in.
