Our skin is called the integumentary system. It is made up of multiple layers of tissue that protect our body from outside elements.
It is our first line of defense against disease and damage. From the outside, it looks like a smooth, continuous surface but there are actually three distinct layers that make up this protective barrier.
The outermost layer is the epidermis which protects us from external elements such as bacteria and other pathogens. This layer also helps to regulate body temperature by trapping heat in when were cold and releasing it when were hot. The epidermis contains cells called melanocytes which produce melanin; a natural pigment that gives skin its color and provides protection from UV rays.
The middle layer is known as the dermis, or true skin. This layer consists of collagen fibers, elastin fibers and sweat glands that give strength to our skin while providing flexibility so it can stretch without tearing apart easily. It also stores fat for energy reserves during times of need and houses nerve endings that allow us to feel various sensations like pressure or pain on our skins surface. This part of the integumentary system also produces oil to keep moisture locked into our bodies – preventing dehydration – as well as producing sebum which acts as an antibacterial agent protecting us from infection-causing microorganisms on the outside world.
Finally, underneath these two layers lies another important one: The subcutaneous tissue (also referred to as hypodermis). This thin sheet of fatty connective tissue binds together all the structures within your body while insulating them against extreme temperatures both internally and externally; making sure they stay at optimal working conditions regardless of their environment.. Additionally this last layer offers cushioning for your internal organs in case you suffer any kind of trauma or impact making sure nothing gets too damaged upon contact with dangerous forces coming from outside sources!
The skin is made up of three distinct layers: the epidermis, dermis, and subcutaneous tissue.
