Verified step by step guidance1
Understand the types of sweat glands in the human body: Apocrine and Eccrine glands are the two main types of sweat glands.
Apocrine glands are primarily located in areas abundant in hair follicles, such as the armpits and groin. They secrete a thicker, milky fluid that is rich in proteins and lipids.
Eccrine glands are distributed throughout the skin and are responsible for regulating body temperature through sweat that is mostly water and salts.
Body odor is mainly caused by the bacterial breakdown of the sweat produced by apocrine glands. The proteins and lipids in apocrine sweat provide a nutrient-rich environment for bacteria, leading to the production of odor.
Ceruminous glands produce earwax, and sebaceous glands secrete sebum, neither of which are primarily responsible for body odor. Focus on the role of apocrine glands in the development of body odor.
