The seven main functions of the skin are protection, regulation, sensation, absorption, excretion, synthesis and storage.
These are all vital to the overall health and well-being of our bodies.
Protection is one of the most important roles of skin, as it helps keep out dirt, germs and other foreign substances that could be harmful if they enter our bodies. It also provides insulation from extreme temperatures and ultraviolet light from the sun. The outermost layer of skin, called epidermis, is composed of tough protein layers which help protect against physical damage as well.
The second main function of skin is regulation; by regulating body temperature through sweat glands located throughout your body you can stay cool when youre hot and warm when you feel cold. This thermoregulation process keeps us comfortable in different environmental conditions. Additionally, sebaceous glands produce oil which acts as a protective barrier for your skin to prevent dehydration or cracking in dry climates or environments with low humidity levels.
Sensation is another major role that our skin plays; receptors found all over our bodies allow us to sense pressure, heat and pain so that we can react accordingly if something touches us unexpectedly or causes discomfort in any way. Without this sensation ability, we wouldn’t be able to tell if something was causing harm before it was too late! Additionally, without these receptors we wouldn’t be able to experience pleasant sensations such as feeling a gentle breeze on a sunny day or being hugged by someone we love dearly either – making life quite dull indeed!
Absorption allows nutrients from food sources like vitamins A & D into our bloodstreams where they become available for use elsewhere in the body while excretion removes waste products such as urea via sweat through pores on our skins surface rather than internally where more serious complications could arise due to its toxicity levels.. Synthesis involves production processes whereby vitamin D3 becomes available upon exposure to sunlight whilst storage capabilities enable fat cells beneath dermal layers helping regulate energy balance within organisms leading healthier lives overall!
Protection: Skin helps keep out dirt, germs and other foreign substances that could be harmful if they enter our bodies. It also provides insulation from extreme temperatures and ultraviolet light from the sun.
Regulation: Sweat glands located throughout your body regulate body temperature and sebaceous glands produce oil which acts as a protective barrier for your skin to prevent dehydration or cracking in dry climates or environments with low humidity levels.
Sensation: Receptors found all over our bodies allow us to sense pressure, heat and pain so that we can react accordingly if something touches us unexpectedly or causes discomfort in any way.
