Which glands are primarily responsible for body odor?

The correct choice is indeed the apocrine glands, which play a significant role in body odor production. Apocrine glands are widely distributed in the body, particularly in areas such as the armpits and groin. They become active during puberty and secrete a thicker, milky fluid that, when broken down by bacteria on the skin’s surface, can produce the characteristic odors associated with body odor.

This process typically involves the secretion of organic compounds that serve as a food source for skin bacteria. As the bacteria metabolize these substances, they produce waste products that have a distinct smell. This is why body odor can often intensify with increased emotional stress or physical activity, as these glands are stimulated during such times.

In contrast, while sebaceous glands are involved in the secretion of oil (sebum) that keeps skin moisturized, they do not contribute to body odor directly. Eccrine glands, which are responsible for regulating body temperature through sweat, primarily secrete a watery, salt-based fluid that does not generate odor. The apoeccrine glands, while sometimes mentioned, are less commonly recognized as contributors to body odor compared to apocrine glands. Therefore, the essence of body odor is most closely linked to the activity of
