Which chamber of the heart receives deoxygenated blood from the body?
Our heart has four chambers, two atria (right and left) and two ventricles (right and left).
The right atrium receives the de-oxygenated blood from the body. From the right atrium blood passes to the right ventricle.
The right ventricle propels this de-oxygenated blood to the lungs though pulmonary artery, for oxygenation. The deoxygenated blood loses carbon-di-oxide and gains oxygen in the lungs. This process is called gaseous exchange.
After the gaseous exchange, blood becomes oxygenated. This oxygenated blood comes to left atrium of the heart through pulmonary veins.
From the left atrium blood comes to the left ventricle. Left ventricle sends this oxygenated blood through aorta and arteries to all organs of the body.
The following diagram shows blood flow through the heart. Here the blue arrows show the flow of de-oxygenated blood. See, the two blue arrows come to the right atrium (2). This is the chamber, which receives the de-oxygenated blood from the body. The red arrows are representing the oxygenated blood.
