Which type of glands includes both eccrine and apocrine types?

The correct answer is sudoriferous glands, which are responsible for producing sweat and are categorized into two main types: eccrine and apocrine glands. Eccrine glands are found all over the body and are crucial for thermoregulation, as they secrete a watery fluid that helps cool the body down through evaporation. In contrast, apocrine glands are primarily located in certain areas such as the armpits and groin and secrete a thicker fluid that can be influenced by emotional factors and is often associated with body odor.

Understanding the classification of these glands is vital in fields like dermatology and forensic science, especially when discussing body temperature regulation and the chemical composition of sweat. Other gland types listed, such as endocrine glands, primarily secrete hormones directly into the bloodstream, while sebaceous glands produce oil and do not include the sweat types. Exocrine glands encompass a broader category that includes sudoriferous glands but also covers various other gland types that secrete substances through ducts, making the answer specifically sudoriferous glands more accurate in this context.
