Instead, this lymph builds up in the tissues causing swelling that can become extreme. Elephantiasis occurs when a microorganism causes obstruction of the lymphatics and results in grossly swollen appendages.

Mechanical energy is potential energy and kinetic energy. It involves such things as gravity and speed. It does not necessarily require a mechanical device be present. Nonmechanical energy is anything else. Electrical energy, heat, nuclear energy, and chemical energy are examples of nonmechanical energy.
How does acute unilateral renal obstruction predispose people to hypertension?
