What problem would be caused by a lack of cartilage in someone's body?

• A. Their Movement Would Be Hindered, And Their Bones Rub Together.
• B. Their Cardiac Muscles Would Fail And In Turn Cause Heart Problems.
• C. Their Muscles Would Fail To Contract.
• D. Their Endoskeleton Would Be Too Flexible.

Answer: (A)

Cartilage acts as a smooth, cushioning surface in joints, allowing bones to glide past one another with minimal friction. Without it, the ends of bones would rub directly together during movement, leading to pain, swelling, and a reduced range of motion. This is why the correct idea is that movement would be hindered and bones would rub together.

Muscle contraction issues, heart (cardiac) problems, or an endoskeleton that’s too flexible aren’t direct consequences of lacking cartilage. Those relate to muscle function, heart tissue, or overall skeletal structure rather than the joint surface lubrication that cartilage provides.
