Which system includes glands such as sebaceous and sudoriferous glands as part of its function?

• A. Digestive System
• B. Integumentary System
• C. Endocrine System
• D. Lymphatic System

Answer: (B)

Glands such as sebaceous and sudoriferous glands are part of the integumentary system, which includes the skin and its appendages. The sebaceous glands secrete sebum to lubricate the skin and hair, helping maintain the protective barrier and antimicrobial properties. Sweat glands produce sweat that cools the body through evaporation and also helps excrete certain wastes. These skin glands work with the skin to regulate temperature, protect against injury and infection, and participate in excretion. The digestive system isn’t focused on skin glands, the endocrine system involves hormone-secreting glands elsewhere in the body, and the lymphatic system deals with immune function and fluid balance, not these skin-specific glands.
