<< previous question next question >>

Explanation:

To solve this, we analyze each option:

• Option A: Synovial fluid is in synovial joints (cavities) and lubricates the cartilage and joint surfaces, reducing friction.
• Option B: Hormone storage for stress response is related to endocrine glands (like adrenal glands), not synovial fluid.
• Option C: Digestion is handled by digestive fluids (e.g., saliva, gastric juice), not synovial fluid.
• Option D: Moisturizing and filtering air is done by respiratory tract structures (e.g., nasal cavity), not synovial fluid.

So the correct answer is A as it matches the role of synovial fluid.

Answer:

A. Lubricating cartilage at joints
