When the animal cannot control things, such as the feeding time or the lighting program, and when it cannot escape from things it finds unpleasant, it often behaves in a manner that indicates frustration.
Cavitation can also cause excessive pump vibration, which could damage pump bearings, wearing rings, and seals. A small number of centrifugal pumps are designed to operate under conditions where cavitation is unavoidable.
Left ventricular hypertrophy (LVH) occurs when the muscle tissue in the heartâs main pumping chamber becomes enlarged. LVH is often caused by high blood pressure or other heart problems and can lead to serious complications, such as heart disease, heart attack and heart failure.
