Integumentary System At Its Finest

By Veronika

What is the Integumentary system?

The Integumentary system (From Latin integumentum, from integere 'to cover') is a bodily system that is formed of the skin and associated with structures including glands (sweat and sebaceous), hair, feathers, scales, nerve receptors, and nails.

FUN FACT: Bed bugs exist solely to eat our dead skin!

What are the functions of this specific system?

There are many different jobs that this system does. The main function is to protect the body from the outside, almost like being a barrier. Many other functions are to protect against diseases, maintain body temperature, protect the body from dehydration, eliminate body temperature, and to be the attachment site for sensory receptors to detect pain, sensation, pressure, and temperature, to store water and fat. In addition, it provides vitamin D synthesis.

FUN FACT: We lose 30,000 to 40,000 dead skin cells every minute!

What are some diseases/disorders that are associated with this system?

As any other system in the body, the Integumentary system can also be affected by many diseases/disorders. Some of them are serious and others are not as much. They are : skin cancer (three types), warts, eczema, acne, vitiligo, psoriasis, and moles. To avoid these things taking good care of the skin will do the trick, it can be as simple as putting on a wide hat to form a shadow from the chest up and a light cover over a bathing suit to not let the sun rays get to much light on your skin.

FUN FACT: Skin is the body's largest organ!

How does it all work?

The body itself is a complicated machine that is made up of many different subsystems. All of these systems have their own purpose in the body and require needed materials to function properly, including the need to communicate to other parts of this complicated machine. This makes the Integumentary system very important because it works with other systems to maintain and support the conditions that your cells, tissues, and organs need to function properly. The immune system works with the Integumentary system very close because tiny glands in the skin secrete oils that enhance the barrier function of the skin. Immune cells live in the skin and provide the first line of defense against infections. Then the next close friend is the digestive system. By working together to encourage the uptake of calcium from our diet. The Integumentary system also works closely with the circulatory system and the surface capillaries that are through your body. They work together because the specific substances enter to the bloodstream with the help of the capillary network.

As we mentioned the skin works to maintain your body temperature. What happens is when temperatures get too hot or too cold your brain sends nerve pulses to the skin which has three ways to either increase or decrease heat loss from the body's surface: hairs on the skin trap more warmth if they are standing up, and less if they are lying flat; glands under the skin secrete sweat onto the surface of the skin in order to increase heat loss by evaporation if the body is too hot; capillaries near the surface can open when your body needs to cool off and close when you need to conserve heat. Another friendly system is the nervous system that is, of course, dependent on neurons embedded in your skin to sense the outside world. A good example would be when you stub your toe, nerve cells in the foot send signals up the leg, through the spinal cord, and up into the brain. The nerve cell connections in the brain sense these signals as pain. This is how the Integumentary system works with other systems in the body.
