Is Cartilage more brittle than Bone?

Cartilage, as a rule, is the slowest healing tissue in the human body. The reason for this is the virtual absence of blood flow in this tissue. Most of the nutrition for cartilage comes from synovial fluid, the lubricating fluid in most of our joints. There are other types of cartilage in the body such as hyaline cartilage, forming the connection in the front of the rib cage. This type is also considered avascular, meaning without blood supply.

Bones on the other hand heal much faster than most tissues because of their rich supply of blood. The blood carries the nessecary building blocks required in the healing process.
