Explanation:
Detailed explanation-1: -Epithelial layers contain no blood vessels (avascular), so they must receive nourishment via diffusion of substances from the underlying connective tissue, through the basement membrane.
Detailed explanation-2: -Epithelial and connective tissue are generally avascular, which means they lack a blood supply. While, Muscle and nervous tissue are vascular tissues, which means they have a strong blood supply.
Detailed explanation-3: -Cartilage is avascular, meaning that it has no blood supply. The lack of blood circulation in cartilage means that it is a very slow-healing type of tissue. Nutrition to cartilage is maintained by fluid in the joints, which lubricates the tissue.
