Final answer:
The papillary canal carries sebum to the hair follicle, which is part of the skin's structure aiding in lubrication and waterproofing of hair and skin.
Step-by-step explanation:
The papillary canal is part of the structure of the skin associated with the passage of sebum. Sebum is an oily substance produced by the sebaceous glands, which are found in the skin connected to hair follicles. The primary function of sebum is to coat and waterproof the hair and skin to prevent them from drying out. This oil makes its way to the surface of the skin by traveling through the hair follicle. Therefore, the papillary canal takes oil (sebum) to the hair follicle.
