What do sweat glands look like?

Sweat glands are small, coiled tubular structures located in the skin. There are two main types: eccrine glands, which are distributed widely across the body and have a simple, coiled appearance, and apocrine glands, which are larger and typically found in areas like the armpits and groin. Eccrine glands have a clear duct leading to the skin surface, while apocrine glands have a more complex structure and are associated with hair follicles. Both types are not visible to the naked eye but can be observed under a microscope.
