Question

which statement best describes the skeletal system?
a. the skeletal system is a system of cartilage that supports the body and makes red
and white blood cells.
b. the skeletal system is composed of bones, cartilage, tendons, and the muscles that
connect them.
c. the skeletal system is composed of a rigid structure of bones that support the body
and make red and white blood cells.
d. the skeletal system is composed of a rigid structure of bones that create strong, hard
tissues called ligaments.

Explanation:

• Option A: The skeletal system is not mainly cartilage; it's mainly bones, so A is incorrect.
• Option B: Muscles are part of the muscular system, not the skeletal system, so B is incorrect.
• Option C: The skeletal system has bones (rigid structure) that support the body and bone marrow in bones makes red and white blood cells, so this is correct.
• Option D: Ligaments connect bones, and bones don't create ligaments; also, the description of the skeletal system's main function here is off, so D is incorrect.

Answer:

C. The skeletal system is composed of a rigid structure of bones that support the body and make red and white blood cells.
