Liver and Heart Diseases

THE CARDIO-VASCULAR system comprises of organs of the body concerned with the manufacture, storage and circulation of the blood, namely, the liver the heart and the arteries. Blood is the most vital fluid in the body and any reduction in its quantity or interruption in its supply or lack of balance among its constituents, as in anemia, gives rise to many diseases, some of which may prove fatal in the long run.

The human body receives its nutrition from the food which is digested in the stomach and turned into blood. Blood courses through the body and restores the tissues and replaces the energy which we lose while we use our body. It is being constantly manufactured, purified and replaced. The heart pumps the blood into the various organs from which it returns to the heart and from there goes to the lungs for oxygenation to be reused. The blood, it should be noted, makes a complete circuit of the body in 15 seconds flat. Its constituents-the red and the white corpuscles and, of course, the platelets-have their own functions to perform. The lack of the red blood corpuscles leads to anemia since the allotted function of the RBCs (red blood corpuscles) is to carry oxygen. The WBCs (white blood corpuscles) are the soldiers provided by nature to fight infection. The platelets help in coagulation of the blood in case of injury-people whose blood is deficient in platelets are always in danger of dying of hemorrhage, because once bleeding starts it will not stop since the blood will refuse the coagulate. The fluid part of the blood (plasma) is the carrier of salt and proteins which nourish the tissues. In its journey from the pump that nature has provided (the heart) to the various parts of the body, blood carries the various waste products like carbonic acid gas (exhaled from the lungs), urea and poisons ejected by the kidneys through the urine. Blood is a general medium of communication between the organs which are chemically interdependent: it carries to the stomach the materials for the gastric juice, to the muscles the ferments formed in the pancreas and absorbs secretions needed for the general purposes of the body, like those of the thyroid and the supra renal glands.
