Exercise 9

During normal production of serous fluid, the slight excess of fluid is:

A. Absorbed by the lymphatic system

B. Absorbed through the visceral capillaries

C. Stored in the mesothelial cells

D. Metabolized by the mesothelial cells

Step 1 of 2

Serous fluid:

The fluid that is present between the serous membranes is termed as serous fluid.

Production of serous fluid:

Serous fluids are generated as ultra filtrates of plasma.

• The production of serous fluid is controlled by the capillaries in cavities, which produces hydrostatic pressure, oncotic pressure, and permeability

• Normally, only a small amount of serous fluid appears in serous membrane

• Because, the capillaries maintain the continuous exchange of serous fluid in serous membrane by producing and absorbing the fluid at constant rate

• Sometimes, parietal capillary and visceral capillary produce some excess serous fluid due to slight different amount of positive pressure

• But, these excess amounts of fluid are reabsorbed by lymphatic capillaries of serous membranes

Therefore, the slight excess of serous fluid produced during normal production is “absorbed by the lymphatic system”. Hence, the correct answer is option.
