Question

multiple choice question
cartilage tissue heals very slowly because:
o there is a high rate of mitotic activity among the chondrocytes
o it lacks a direct blood supply
o it is highly vascularized

Explanation:

Cartilage lacks a direct blood - supply. Blood vessels are crucial for transporting nutrients and immune cells necessary for tissue repair. Without a direct blood supply, the delivery of these substances is slow, leading to slow healing. High mitotic activity would aid in faster healing, and being highly vascularized is the opposite of what cartilage is.

Answer:

it lacks a direct blood supply
