The human heart is made of very strong muscle. This organ consists of four chambers which pump blood around the body by squeezing and relaxing in a regular rhythm. The heart beats on average 70 times per minute. This might be more or less depending on a person's age, fitness level, and other health factors. The heart has a special area which acts as a pacemaker. This area creates an electrical impulse like a small electric shock which makes the chambers of the heart contract at the correct time. This ensures the blood is pumped in the right direction and at a speed that is suitable for the body's needs.
