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 (within bones) produces red and white blood cells. This is a correct function of the skeletal system.
• Option B: The skeletal system is made of bones and cartilage, but muscle is part of the muscular system, not the skeletal system. So B is incorrect.
• Option C: The skeletal system does not provide potassium for support. Potassium has other roles in the body, and support from the skeletal system is due to the structure of bones, not potassium provision. So C is incorrect.
• Option D: Ligaments are connective tissues, but they are not manufactured by the skeletal system. They connect bones but are not produced by the skeletal system itself. So D is incorrect.

Answer:

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