Question
Removal of body waste is carried out by
- Excretory system
- Nervous system
- Circulatory system
- Digestive system
Hint:
The removal of waste is known as excretion.
The correct answer is: Excretory system
- The removal of body waste is carried out by the excretory system.
- This system involves the kidneys, urinary bladder, ureter, and urethra. All these parts work in a coordinated manner to cause the removal of waste substances from the body.
- The other options are incorrect because the circulatory system is responsible for the transportation of blood to different parts of the body. The digestive system is known for breaking down complex substances into simpler ones and absorbing nutrients. And the nervous system is responsible for transporting nerve signals to our brain for required action.
The kidneys are the main organ of the excretory system.
