What are whiteheads and blackheads examples of?

Pores
Lesions
Scabs
Scars

The correct answer is: Lesions

Whiteheads and blackheads are examples of lesions. In dermatology, a lesion refers to any abnormal tissue found on or in the body. This includes a wide range of skin conditions, such as acne, which is characterized by the presence of whiteheads and blackheads. Whiteheads occur when a pore becomes clogged with oil, dead skin cells, and bacteria, leading to a closed comedone that has a white or flesh-colored appearance. On the other hand, blackheads are open comedones where the clogged material is exposed to air, oxidizing and turning dark. Both conditions are directly related to the inflammatory response in the skin and are manifestations of acne. Pores are tiny openings in the skin, but they do not specifically describe the condition of whiteheads and blackheads, as these are actual skin abnormalities rather than mere openings. Scabs refer to a protective crust that forms over a wound during healing, and scars are areas of fibrous tissue that replace normal skin after an injury or condition has healed. Thus, when classifying whiteheads and blackheads, lesions accurately encapsulate their nature as skin imperfections resulting from blocked follicles.
