MCAT Question of the Day
    •

    Q:

    		 Hydrostatic pressure of the blood in tissues is greater than its osmotic pressure, which causes leakage of fluid into the tissues. The reason this fluid does not accumulate and lead to persistent swelling is because:
    		 

    A

    		 interstitial fluid is excreted as urine.

    B

    		 interstitial fluid is returned to the circulatory system via the lymphatic system.

    C

    		 interstitial fluid is released via sweating and respiration.

    D

    		 the osmotic pressure is greater than the hydrostatic pressure in other tissues, allowing for fluid to return directly to circulation via diffusion into the blood.
