What is the integumentary system?

It is a system that protects the body from different types of damage and it includes skin, hair, and nails.

5 ways the integumentary system helps you

  1. It protects the body's internal living tissues and organs.
  2. It protects against invasion by infectious organisms.
  3. It protects the body against sudden changes in temperature.
  4. It helps excrete waste materials through perspiration.
  5. It acts as a receptor for touch, pressure, pain, heat, and cold.

System's Organs and Tissues

Epidermis: The outer layer of the skin is called the epidermis. The epidermis acts as a barrier against pathogens from entering the body.

Dermis: This is the inner layer of the skin which is called dermis. It consists of dense irregular connective tissue and is much thicker than the epidermis.

Hair and nail tissue: Hair and nails are a modified type of skin. Hair grows everywhere on the body but on the palms of your hands and the soles of your feet. Nails protect the sensitive tips of fingers and toes.

Ailments Related to the System

Sunburn: Sunburn is caused by UV radiation either from the sun or artificial sources. The most common symptoms are redness and pain but there's also itching, peeling skin, and rashes. Sunburns heal best over time and no doctor needs to get involved. Taking aspirin can relieve the pain and putting on aloe vera can soothe the burn.

Athlete's foot: It is caused by fungi which inhabit dead layers of skin and digest keratin. The symptoms are itchiness, dryness, and peeling of the skin. Once more, no doctor is needed but you should wash your feet properly twice a day and then apply topical medication.

Rash: There is a wide variety of things that cause rashes. Some symptoms can include having a fever. Treatments differ according to what kind of rash you have but common rashes need topical creams.

Integumentary and Nervous System

The integumentary system and the nervous system work together because there are nerves under your skin which help you feel.
