Question

Read the following passage carefully and answer the questions given below it.


The heart is made up of four chambers. The upper two chambers are called atrium

and the lower two are known as ventricles. Muscular walls, called septa or septum,

divide the heart into two sides. On the right side of the heart, the right atrium and

ventricle work to pump oxygen-poor blood to the lungs. On the left side, the left

atrium and ventricle combine to pump oxygenated blood to the body.


The four chambers of the heart are attached to major veins or arteries that either

bring blood into or carry blood away from the heart. The right atrium receives
oxygen-poor blood from the two largest veins in the body, the superior and inferior
vena cava. The left atrium receives oxygenated blood from the lungs through the
pulmonary veins. Both atrium then pump their supply of blood into the ventricles.

The ventricles are the shipping stations of the heart. The right ventricle
pumps oxygen-poor blood into the lungs through the pulmonary artery while the

left ventricle pumps oxygenated blood to the body through the aorta, the largest

artery in the body.


There are four valves within the heart. These valves open when blood passes

through them and then close to keep the blood from flowing in the wrong
direction.
