The hydrostatic pressure inside the lymph nodes is due to the? A) Difference in total diameters between the afferent and efferent lymphatic vessels. B) The afferent vessels equal in number the efferent lymphatic vessels. C) The arterial blood pressure. D) The proteins in the lymph.

The correct answer to the question presented above is:

C) The arterial blood pressure. The effect of hydrostatic pressure inside the lymph nodes depends on the condition of the blood vessels. When hydrostatic pressure is increased, the significant amount of protein is dependent on the continuous exchange of lymph protein during nodal transit.
