Which of the following describes a function of cartilage?

Which of the following describes a function of cartilage?

• A. Acts as a shock absorber
• B. Pumps blood
• C. Stores fat
• D. Transmits nerve signals

Answer: (A)

Cartilage primarily cushions joints, providing a smooth, resilient surface that absorbs impact and reduces friction between bones during movement. This shocks-absorbing property helps distribute loads across the joint and protects bone surfaces from wear over time. That makes the description of acting as a shock absorber the best match. Pumping blood is the function of the heart, storing fat is a job for adipose tissue, and transmitting nerve signals is handled by nervous tissue, not cartilage. Cartilage is avascular, relies on nearby fluids for nutrients, and plays its role by supporting joint health and movement rather than carrying out those other activities.
