Question

which two body systems function together to provide oxygen for the cells of the body?
∘ respiratory and nervous
∘ integumentary and respiratory
∘ musculoskeletal and nervous
∘ respiratory and circulatory

Explanation:

To determine the two body systems that provide oxygen to cells, we analyze each option:

• Respiratory and nervous: The nervous system controls functions but doesn't transport oxygen. Eliminate.
• Integumentary and respiratory: The integumentary system (skin, etc.) is for protection, not oxygen delivery. Eliminate.
• Musculoskeletal and nervous: These systems are for movement and control, not oxygen supply. Eliminate.
• Respiratory and circulatory: The respiratory system takes in oxygen, and the circulatory system (blood vessels, heart) transports it to cells. This matches the requirement.

Answer:

D. Respiratory and circulatory
