A Cause of Heart Failure
The heart is an organ which frequently fails in the dog and surprisingly, it happens to dogs of all ages. In the young, this is typically the result of congenital abnormalities in the formation of the heart or blood vessels, which surround it. In older animals, it is usually a case in which one side or chamber is weakened or over worked due to altered circulatory patterns.
The heart is a pump
The heart is actually nothing more than a mechanical pump. It accepts blood on one side and forces it through the lungs, then its other half pumps the liquid on through the entire body. The heart does not change or alter the blood in any way. It has no glandular tissue and therefore secretes nothing into the blood nor does it extract anything. It is probably the simplest and most easily understood organ in the entire body.
