Publisher's Synopsis
The human heart is one of the most important organs in the entire human body. It is really nothing more than a pump that is composed of muscles which pump blood throughout the entire body, beating approximately 72 times per minute of our lives.The heart pumps the blood, which carries all the vital materials which help our bodies function and removes the waste products that we do not need. For example, the brain requires oxygen and glucose, which, if not received continuously, will cause it to lose consciousness. Muscles need oxygen, glucose and amino acids, as well as the proper ratio of sodium, calcium and potassium salts in order to contract normally. The glands need sufficient supplies of raw materials from which to manufacture the specific secretions. If the heart ever ceases to pump blood the body begins to shut down and after a very short period of time it dies. On the other hand, the immune system is a vast network of cells and tissues which is constantly on the lookout for invaders, and once an enemy is spotted, a complex attack is mounted. The immune system is very essential for survival. Without an immune system, our bodies would be open to attack from bacteria, viruses, parasites, and many more. It is the immune system that keeps the body healthy as it drifts through a sea of pathogens.This book goes beyond the ordinary to elaborate clearly on the two conditions that affect these two systems (Heart Failure and Rheumatic Fever). It makes these two conditions well understood with one time reading. The book goes into an extra mile to explain their management in a well elaborated manner.
