IMMUNOLOGY

Detailed explanation-1: -Edema is swelling of soft tissues due to increased interstitial fluid. The fluid is predominantly water, but protein and cell-rich fluid can accumulate if there is infection or lymphatic obstruction. Edema may be generalized or local (eg, limited to a single extremity or part of an extremity).

Detailed explanation-2: -Edema means swelling caused by fluid in your body’s tissues. It usually occurs in the feet, ankles and legs, but it can involve your entire body.

Detailed explanation-3: -Edema is swelling caused by too much fluid trapped in the body’s tissues. Edema can affect any part of the body. But it’s more likely to show up in the legs and feet. Medicines and pregnancy can cause edema.

Detailed explanation-4: -Interstitial lung edema arises almost exclusively due to an increase of the pulmonary capillary hydrostatic pressure (Pcap), which occurs most commonly in left sided heart failure, hence it is a key element of cardiogenic lung edema.
