The centre is a hollow declamatory muscular organ that is hardened between the lungs, and is in the nerve centre of the chest. The heart pumps transmission line through the body, which supplies the cells with oxygen and nutrients, and removes carbon dioxide and deplete products such as lactic acid and urea. It is attached to the breastbone by special connector tissues called ligaments. The heart has four put ups, a small upper chamber, which is called the atrium, and a large lower chamber called the ventricle, it has one of these on each side. The septum divides the heart in to its cardinal separate pumps, the lef t and the right. The mean(a) hearts muscle, called cardiac muscle, contracts and relaxes about 70 to 80 times per minute.

The heart to a fault contains valves on either side, it contains an Aortic valve that stops the backflow of alliance from the aorta into the ventricles, the Bicuspid valve which has two cusps, this also stops backflow of blood from the ventricle to the atria, as the left ventricle contracts the bicuspidate valve stops blood outlet backwards, Tricuspid valve, has three cusps and this also stops the backflow of blood to the atria when the right ventricle contracts, and eventually the Pulmonary valve which stops blood back flowing throug! h the ventricle from the pulmonary artery. Deoxygenated blood enters the right atria from the superior and substandard vena cavae. The right atrium thusly fills with blood, the blood passes through a one-way valve that takes the...
