Final answer:
The papillary canal transports sebum to the hair follicles, which are located in the dermis layer of the skin.
Step-by-step explanation:
The papillary canal, which transports sebum, releases its contents into the hair follicles. Sebum is an oily substance produced by the sebaceous glands associated with each hair follicle. This sebum waterproofs the hair and skin to prevent them from drying out. The hair follicles, alongside sebaceous glands, are located within the dermis layer of the skin, even though they originate from epidermal tissue. Therefore, the papillary canal takes oil (sebum) to the d. Hair follicles.
