Where are the blood vessels that nourish the hair located?

Hair shaft
Hair follicle
Hair papilla
Hair bulb

The correct answer is: Hair papilla

The nourishing blood vessels for hair are located in the hair papilla. The hair papilla is a small, cone-shaped structure at the base of the hair follicle, and it contains capillaries that supply the necessary nutrients and oxygen for hair growth. This is crucial as the health of the hair follicle and the rate of hair growth largely depend on the blood supply provided by the hair papilla. While the hair follicle is the structure that houses the hair root and is involved in the growth process, it does not directly supply nutrients. The hair bulb, situated at the lower part of the follicle where hair begins to grow, also has an indirect relationship with the blood supply through the papilla. The hair shaft itself is the visible part of the hair that extends outside the skin and is formed from dead cells; it does not have any living structures or blood vessels.
