Final answer:
Sweat glands can be categorized into eccrine and apocrine glands, each with distinct characteristics. Eccrine glands are coiled and found throughout the body, releasing mostly water. Apocrine glands are associated with hair follicles in certain areas, produce sweat with organic compounds, and are subject to bacterial decomposition and odor.
Step-by-step explanation:
Sweat glands can be classified into two types: eccrine glands and apocrine glands. Eccrine sweat glands are coiled glands in the dermis that release mostly water. They are found all over the body and help regulate body temperature. Apocrine sweat glands, on the other hand, are associated with hair follicles in areas such as the armpits and genital regions. These glands are larger, lie deeper in the dermis, and release sweat that includes organic compounds, making it thicker and subject to bacterial decomposition and smell.
