Cartilage vs Bone

	Structure	Nutrition	Turnover
Cartilage (Hyaline)	Collagen type II. Proteo Glycans that contain GAGS. Chondrocytes that produce matrix. 60-80% water content	Alot of GAGS makes the water content high which allows for nutrient diffusion. No blood vessels!	Not able to repair when damaged. It is because the avascular structure. It calcifies instead.
Compact bone	Mineralized extra cellular matrix (ECM). Collagen type I. Osteocytes that recide in lacuna. Each lacuna is connected to the blood vessels through canaliculi.	The blood vessels supply the osteocytes.	Bone remodelling occurs when damaged. Compact bone is an important calcium deposit. There is a constant bone turnover. Osteoblasts build up Osteoclasts tear down.
