The term pore is a standard reference to small openings in the skin or surface of an organism or structure, which means that most everything has some type of a pore. Plants, animals, humans, and even rocks have pores, but they are not the same.
Mammals all have two types of pores that occur in various sizes, depending on the organism. Sweat ducts are pores that ooze sweat, as your sweat glands act as a natural cooling system, secreting sweat, which evaporates into the air. The sebaceous glands are responsible for blemishes and zits.
They also moisturize your skin as well as offer a degree of water repellency through oily secretions. Pores operate as the opening in an exterior where microscopic particles can pass. Pores are additionally the opening at the top of our hair follicles.
