Why this is the answer
The sweat glands are technically called sudoriferous glands. They secrete sweat (perspiration), which helps regulate body temperature through evaporative cooling and excretes a small amount of waste. They are distinct from the sebaceous (oil) glands, which secrete sebum to lubricate skin and hair. Both gland types are located in the dermis. Cosmetologists learn the two main types of skin glands and their functions as part of basic skin science, and the terminology is frequently tested on the exam.
