Question
The main organ of the circulatory system is
- Lymph
- Blood
- Blood vessels
- Heart
Hint:
The pumping organ is the main organ of the circulatory system.
The correct answer is: Heart
- The main organ of the circulatory system is the heart.
- The circulatory system refers to the system in our body that is responsible for providing blood and fluid to all parts. This includes the heart, blood vessels like arteries, veins, capillaries, and blood.
- Out of these, the main organ responsible for pumping blood is the heart. It is a muscular organ that has four chamber and vessels which takes oxygenated blood from the lungs and send it to the body organs. At the same time, it takes deoxygenated blood from the body organs and passes it to the lungs.
- Thus, the heart is the most essential part of the circulatory system. Without this, the system might fail.
The blood passes through the heart, twice for a properly regulated circulation.
