Question

How many chambers are there in the heart of humans?
a. Two
b. Three
c. Four
d. Five

Answer 1

Hint: As we know, human beings are the most sophisticated organisms present in the world. So, they need a circulatory system that can provide the required amount of energy to them. The human heart has two functions. One is to circulate oxygenated blood throughout the body and replenish the deoxygenated blood with oxygen gas in it.

Complete answer:
- The human heart consists of four chambers which help in supplying the blood to all body parts. The blood first enters the heart through the right ventricle.

- The right ventricle participates in pumping the blood to the lungs where the blood becomes oxygenated.

- From the lungs, the pulmonary veins which enter the left atrium are responsible to bring back the oxygenated blood to the heart.

- The blood flows into the left ventricle from the left atrium.

- The blood gets pumped to the left ventricle to the aorta which is responsible to distribute the oxygenated blood to all parts of the human body.

Hence, The correct answer is option (C).

Additional information:
Among all the four chambers of the human heart, the left ventricle is said to the largest and sturdiest chamber in the heart. The chamber of the left ventricle walls is thick only about a half-inch; however, they have adequate force to push the blood over the aortic valve and into the body.

Note: Here, we need to note that the upper two chambers of the human heart are called arteries. Moreover, the lower two chambers of the human heart are called ventricles. After observing, the scientists said that the left ventricle of the human heart is the smallest chamber of the human heart.
