Question

after listening to a long discussion on the skeletal system, you conclude that the skeletal system is important because it __________. a. supports the body and makes red and white blood cells b. is formed from bones, cartilage, and muscle c. provides the body with potassium needed for support d. manufactures the ligaments needed to connect bones please select the best answer from the choices provided. a b c d

Explanation:

• Option A: The skeletal system supports the body, and bone marrow (part of the skeletal system) produces red and white blood cells. This is a key function of the skeletal system.
• Option B: The skeletal system is formed from bones and cartilage, but muscle is part of the muscular system, so this is incorrect.
• Option C: The skeletal system stores minerals like calcium and phosphorus, not potassium for support in this way, so this is incorrect.
• Option D: Ligaments are connective tissues, but the skeletal system (bones, etc.) does not manufacture ligaments; ligaments connect bones but are not produced by the skeletal system's main structures (bones) in that way, so this is incorrect.

Answer:

A. supports the body and makes red and white blood cells
