Question

Which of the following systems is responsible for producing enzymes that aid in breaking down of complex substances to be absorbed for the body's growth and repair?

• A. Respiratory system
• B. Digestive system
• C. Circulatory system
• D. Nervous system

Answer 1

The correct option is B Digestive system

Digestion of food is brought about by the digestive system. The process of digestion begins in the mouth where food is partially broken down with the help of saliva. This food passes through the esophagus into the stomach, followed by the small intestine and the large intestine where it is acted upon by various enzymes that break it into simpler components. The simple components are absorbed into the body and used for growth and repair. The undigested food is excreted through the anus. Thus the correct answer is option B.
