The source of oxygen and nutrients for articular cartilage is the surrounding synovial fluid.

Here's a step-by-step explanation:

1. Articular cartilage is a type of connective tissue that covers the ends of bones in synovial joints. It is avascular, meaning it does not have its own blood supply.

2. Because it lacks a direct blood supply, articular cartilage relies on diffusion for the delivery of nutrients and oxygen.

3. This diffusion occurs through the synovial fluid, a viscous, non-Newtonian fluid found in the cavities of synovial joints.

4. When the joint is in motion, the pressure causes the synovial fluid to be squeezed out of the cartilage, allowing fresh synovial fluid rich in nutrients and oxygen to diffuse back into the cartilage once the pressure is released.

5. Therefore, the surrounding synovial fluid is the source of oxygen and nutrients for articular cartilage.
