Answer:
4 Chambers
Explanation:
The heart has four chambers: two atria and two ventricles. The right atrium receives oxygen-poor blood from the body and pumps it to the right ventricle.
The heart has a four-chamber system to enable oxygenated blood and deoxygenated blood to be kept separate from each other. The heart pumps oxygenated blood from the lungs to the body and deoxygenated from the body to the lungs to enable re-oxygenation
Complete answer:
Heart is a muscular organ. The conduction system causes the heart to beat rhythmically. It contracts and relaxes continuously.
In humans the right side of the heart receives deoxygenated blood. This blood enters the lungs to get purified. The oxygenated blood then enters the heart again and then circulates throughout the body. Thus the blood comes in contact with the heart twice. This is double circulation. Throughout the circulation, the right and the left side blood never gets mixed. This is because of septum between the two sides.
Heart consists of receiving chambers. These are known as Auricles of Atria. These chambers receive blood from the body and from the lungs. The blood flowing from the body into the heart is deoxygenated whereas the blood entering from the lungs into the heart is oxygenated. Thus to avoid mixing, there are two receiving chambers. These are the Left Auricle and the Right Auricle.
The blood from Auricles enters the distributing chambers. These are known as Ventricles.The oxygenated blood circulates in the body and deoxygenated blood enters the lungs. Thus to avoid mixing, there are two distributing chambers also. These are the Left Ventricle and the Right Ventricle.
Receiving chambers are smaller and Distributing chambers are larger in size.
