Document Summary
Edema is an abnormal accumulation of fluid in tissues. It is due to a change in one of the 4 pressures discussed previously or failure of the lymphatic system to properly drain the fluid that normally moves into the if. Causes of edema include increased map, myxedema (protein deposition in tissues related to hypothyroidism), kwashiorkor (decreased plasma protein), allergic reaction (movement of plasma proteins into interstitial fluid through leaky capillary walls), venous obstruction (local increase capillary. Bp), and blockage of lymphatic drainage channels (e. g. , filariasis, which is an infection by parasitic filarial worms). You should be able to discuss why each of these results in edema. You are welcome to share your ideas to get feedback by posting on the discussion board. For each of the causes of edema listed in the table (increased mean arterial pressure, leakage of plasma protein into the if, myxedma, and decreased plasma protein) indicate which of the pressures (bp, bcop,
