The answer is apocrine gland: thermoregulation
Explanation: The gland can be classified into two types: eccrine and apocrine sweat glands. Eccrines are those that release their secretion without loss of the secretory cell cytoplasm. Already the apocrines eliminate secretion with portions of the cytoplasm.
Apocrine sweat glands are less frequent and are located in the armpits, mammary areolas, genital region and perianal region. These glands begin to function at puberty and the secretion varies according to their location and also the action of sex hormones. However, in general, this secretion is more viscous when compared to that eliminated by the eccrine glands. Another point worth mentioning is the fact that the secretion produced by these glands is eliminated in the hair follicle channels, unlike merocrine, which throws on the body surface.
