Homework Answers

Answer #1

Option-b-Cartilage has the poorest blood supply.

Cartilage is avascular and aneural as it does not contain any blood vessels and nerves, respectively.

Cartilage gets its nutrition through diffusion when there is fluid flow due to compression of the articular cartilage or flexion of the elastic cartilage. Due to its avascularity, the repair of cartilage is very poor.

Dense irregular connective tissue is poorly vascularized but it is not avascular tissue like cartilage.

Adipose tissue has dense vascularization. It contains many small blood vessels.

Bones also have a rich vascular supply. Blood supply of bones varies due to their sizes and their function, for example, the rich blood supply to bones which are long and contain red bone marrow.

Loose irregular connective tissue is also vascularised and it provides nutrition to the epithelium resting on it.
