cartilage has no blood supply.
Connective tissue may or may not be avascular - it depends on the composition of the connective tissue. Avascular tissue is any tissue that does not contain blood vessels or lymphatics. Examples include epithelial tissue layers and the cornea. Elastic fibers, a form of connective tissue is avascular, but muscle is vascular.
no veins in cartilage.
Bone has more resilience, cartilage has faster regeneration, and cartilage is avascular.
vascular
Cartilage is avascular.
Cartilage takes longest to heal because it is avascular.
All epithelial tissue is avascular
cartilage
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.
Bone is far more vascular than cartilage, which means the bone receives nutrients/oxygen/other good stuff more and easier than cartilage. Cartilage has almost no blood supply, which makes healing difficult. Hope that helps..
Cartilage is avascular, meaning no blood supply. This is why cartilage is so long to heal and most often irreplaceable if damaged severely enough. The epidermis and subcutaneous connective tissues are vascular.
Yes, the epidermis itself is avascular, because the cells of the epidermis are not alive. The dermis layer of skin however, relies on blood vessels.
