Which best describes a pore in the skin?

A pore in the skin is best described as a tiny opening for sweat and oil. Pores are small openings on the surface of the skin that allow sweat and sebum, the natural oil produced by sebaceous glands, to be released. This function is essential for maintaining skin hydration and regulating body temperature through perspiration.

Additionally, the structure of a pore is formed by the opening of hair follicles and sweat glands, which are crucial for the skin's thermoregulatory functions and overall health. Understanding the role of pores in the integumentary system is important for recognizing how they contribute to skin care, acne development, and the maintenance of skin balance.
