Your skin is covered in pores that create outlets for exocrine glands. Exocrine glands are glands that carry substances (sweat, oil) out of your skin by way of duct. Examples of exocrine glands include sweat, salivary, mammary, ceruminous, lacrimal, sebaceous, and mucous.
Every hair follicle on the human skin emerges from a pore. But not every pore contains a hair follicle. Wherever there is a strand of hair there is a pore. But some pores are just outlets for glads such as sebaceous follicles that lead sebum out of the body or eccrine glands that lead sweat out of the body on your palms, feet and forehead.
