The structure of the heart


The heart is a large muscular pump and is divided into two halves - the right-hand side and the left-hand side. The right-hand side of the heart is responsible for pumping deoxygenated blood to the lungs. The left-hand side pumps oxygenated blood around the body.

Heart Chambers, Valves, Vessels, Wall and Conduction System. The heart is made up of four chambers. The upper two chambers are called atria (singular: atrium) and the lower two are known as ventricles (singular: ventricle). Muscular walls, called septa or septum, divide the heart into two sides.
*****************************************************************************************************************************************************************************************************************
The right atrium receives oxygen-poor blood from the body and pumps it to the right ventricle through the tricuspid valve.
The right ventricle pumps the oxygen-poor blood to the lungs through the pulmonary valve.
**************************************************************************************************************************************************************************************************************
It's the muscle at the centre of your circulation system, pumping blood around your body as your heart beats. This blood sends oxygen and nutrients to all parts of your body, and carries away unwanted carbon dioxide and waste products.

Pumping oxygenated blood to the other body parts.
Pumping hormones and other vital substances to different parts of the body.
Receiving deoxygenated blood and carrying metabolic waste products from the body and pumping it to the lungs for oxygenation.
Maintaining blood pressure.

The human heart is a four-chambered muscular organ, shaped and sized roughly like a man's closed fist with two-thirds of the mass to the left of midline. The heart is enclosed in a pericardial sac that is lined with the parietal layers of a serous membrane.

How many parts are there in a heart?
Your heart is about the same size as a pear.


It has four parts, the left ventricle (say ven-trik-ul) and the right ventricle which are both at the bottom of the heart, and the left atrium (say ay-tree-um) and the right atrium at the top. A wall of muscle called the septum separates them.

Take an aspirin. Chew one uncoated 325-milligram aspirin (not a baby aspirin). It may not stop the heart attack, but it could lessen the damage by thinning the blood and breaking up clots. Take nitroglycerin for chest pain if you have a prescription.
