Do nutrients diffuse quickly through cartilage matrix but very poorly solid bone matrix?

No, nutrients diffuse very slowly through cartilage matrix and poorly through solid bone matrix.

Due to the absence of blood vessels and presence of a low percentage of water, the diffusion rate of nutrients is extremely slow in cartilage. On the other hand, the diffusion of nutrients through the solid bone matrix is slightly faster than in the cartilage but is still much slower compared to the diffusion of nutrients in soft tissues.
