Question

the ________ is the body system that breaks food down so that it can be used by the body. options: respiratory system, digestive system, skeletal system, circulatory system

Explanation:

To solve this, we analyze each option:

• Respiratory system: Deals with gas exchange (oxygen and carbon dioxide), not food breakdown.
• Digestive system: Its function is to break down food into nutrients the body can use.
• Skeletal system: Provides structure, support, and protection, not food processing.
• Circulatory system: Transports nutrients, oxygen, etc., but doesn't break down food.

So the correct answer is the digestive system.

Answer:

B. digestive system
