What does the integumentary system primarily protect the body from?

The integumentary system primarily protects the body from environmental hazards, which include factors such as UV radiation, chemicals, and physical injuries. The skin acts as a barrier, preventing harmful substances and microorganisms from entering the body, thus serving a crucial role in overall health and safety.

While the system also plays a role in protecting against infection, regulating temperature, and preventing dehydration, the main focus is on the comprehensive protection against various environmental threats. This protective function of the integumentary system is vital for maintaining homeostasis and overall bodily function.
