- A) Respiratory system
- B) Circulatory system
- C) Digestive system
- D) Nervous system

Explanation:
The digestive system is responsible for breaking down food into smaller molecules (e.g., glucose, amino acids, and fatty acids) that can be absorbed and used by the body. This process involves organs like the mouth, esophagus, stomach, small intestine, and large intestine.

Correct Answer: C) Digestive system

Question 3:

What body system controls movement of the human body?

- Options:
- A) Digestive system
- B) Nervous system
- C) Circulatory system
- D) Respiratory system

Question 4:

What body system takes oxygen into the body and gives off carbon dioxide?

- Options:
- A) Circulatory system
- B) Nervous system
- C) Respiratory system
- D) Digestive system

Explanation:
The respiratory system is responsible for gas exchange in the body. It takes in oxygen from the air through the lungs and expels carbon dioxide, a waste product of cellular respiration, back into the atmosphere. Key components include the nose, trachea, bronchi, and lungs.

Correct Answer: C) Respiratory system

Question 5:

The digestive system is made up of which of the following organs?

- Options:
- A) Esophagus, stomach, small intestine, and large intestine
- B) Brain, nerves, and spinal cord
- C) Mouth, brain, and large intestine
- D) Trachea, lungs, and heart

Explanation:
The digestive system consists of organs that work together to break down food and absorb nutrients. The correct organs listed are the esophagus, stomach, small intestine, and large intestine. The brain, nerves, spinal cord, trachea, lungs, and heart belong to other body systems (nervous system, respiratory system, etc.).

Correct Answer: A) Esophagus, stomach, small intestine, and large intestine
