If cartilage doesn’t have its own blood supply and cant repair itself, how is it helped or hurt by drug therapy or good or bad lifestyle choices?

Question

It seems very isolated from the other body systems but what goes on in the body still affects it?

Answer 1

It might not have its own blood supply but that doesn’t mean it gets no blood or no nutrients from blood.

It is harder to specifically target cartilage with drug therapies but they will still work when taken properly. The capillaries and blood vessels nearby will still deliver nutrients by diffusion. Alot of body parts are provided for this way like skin, the largest organ in the body. Larger more important organs have their own direct blood supply such as the heart, liver etc.
