Cosmetology Anatomy & Physiology Practice Test 2026 – Complete Exam Prep

Sweat glands are specialized structures in the skin that play a crucial role in thermoregulation and waste excretion. There are two main types of sweat glands: eccrine and apocrine. Eccrine glands are found throughout the body and are involved in regulating body temperature through the production of a watery, salty fluid. Apocrine glands, located mainly in areas such as the armpits and groin, secrete a thicker, milky fluid that can be associated with body odor.

The correct choice highlights the specific function of sweat glands in the body and how they contribute to the process of sweating. Understanding the function and types of sweat glands is fundamental in cosmetology, as it relates to skin health and can influence the services provided, such as skin treatments and recommendations for clients.

Other glands mentioned, such as sebaceous glands, primarily secrete oil (sebum) to lubricate the skin and hair, while endocrine glands are responsible for hormone production and regulation, which is separate from the function of sweat production.
