This helpful source also highlights the many different ways that the integumentary system interacts with other systems in the body—like the circulatory, immune, and digestive systems—reminding us that it’s part of a whole structure.
The skin’s role as an immune organ is one of its most important functions: this source does a deep dive into its immune function. These other links will tell you more about the workings of Langerhans Cells, T-cells, and the fascinating microbial communities that live on the surface of your body.
You may also be interested in discovering just how much skin we shed on a daily basis—and the tiny critters that feed on it!
If you’re curious about the system’s important thermoregulatory role, you can turn to these sources for a good overview. If you’d like a little more in-depth information about thermoregulation, this one is a good one to consult.
A major feature of the integumentary system is hair—but have you ever considered why we actually have it? These sources will reveal lots about the importance of human hair and the role it plays in protecting us from physical harm. Interestingly, our relative hairlessness as a species actually makes us quite rare in the animal kingdom. Read here to find out why.
When most people think about skin, they think of its sensory role in our lives. In fact, the skin is so effective at sensing the world around us that some researchers are trying to imitate it. Technology that mimics skin could help people with artificial limbs sense things, or enable buildings to sense cracks in their facades so that they can be repaired.
