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 mostly bones, so A is incorrect.
• Option B: Muscles are part of the muscular system, not the skeletal system, so B is wrong.
• Option C: The skeletal system has bones (rigid structure) that support the body and bone marrow in bones makes red and white blood cells, which is correct.
• Option D: Ligaments are connective tissues between bones, not created by bones as "strong, hard tissues" in this misdefined way, 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.
