The integumentary system is the body’s outermost layer of protection, consisting of the skin, hair, nails, and associated glands:
• The skin is the largest organ of the body and has multiple functions, including protecting the body from external physical, chemical, and biological agents, regulating body temperature, and acting as a sensory organ.
• The hair and nails are specialized structures of the skin that serve various protective and sensory functions.
• The associated glands, such as sweat glands and sebaceous glands, secrete substances that help regulate body temperature and protect against pathogens.
Together, these structures make up the integumentary system, which is essential for maintaining homeostasis and protecting the body from the external environment.
