The Formation of Lymph Increases as a Result Of

Question

The formation of lymph increases as a result of
A)increasing osmotic pressure in blood capillaries.
B)increasing hydrostatic pressure in tissue fluid.
C)decreasing volume of tissue fluid.
D)decreasing protein concentration in tissue fluid.

Accepted Answer

The formation of lymph occurs due to an increase in hydrostatic pressure in tissue fluid, which causes a net movement of fluid from the tissue into the lymphatic vessels. This process is aided by the contraction of smooth muscle in the lymphatic vessel walls and the presence of one-way valves. Lymph formation can also be increased by decreased osmotic pressure, increased protein concentration, or increased volume of the interstitial fluid, which affects the balance of forces that govern fluid movement. However, the only answer choice that specifically addresses an increase in lymph formation is B.
