In these diseases, edema occurs primarily because of the body's retention of too much salt (sodium chloride). The excess salt causes the body to retain water, which then leaks into the interstitial tissue spaces, where it appears as edema. Medications also can cause pitting edema. The most common local conditions that cause edema are varicose veins and thrombophlebitis (inflammation of the veins) of the deep veins of the legs.

Further adaptations allow them to tear up and eat the meat while getting rid of the animal parts which they cannot digest. Before an overview about what do hawks eat, let us take a look at the unique features which contribute towards their success as predators.
