The Integumentary System

Function of System:

To protect and cover the body, retain fluids, regulate body temperature, eliminate waste, and protect against disease.

How it aids in homeostasis:

Regulates body temperature and prevents the body from receiving diseases also keeps essential fluids within the body

Name and function of Major Organs:

Skin, hair, nails, and exocrine glands.

Comparative anatomy:

Unlike humans, frogs have the ability to absorb water through their skin to drink it and this is done through their Cutaneous Membrane. They also have the ability to camouflage due to the Chromatophores which are the black spots on their backs. They then have the Nicitating Membrane, which covers their eyes from water and debris, and the Tympanic Membrane which allows them to sense vibrations.

Fish have scales to protect their bodies where humans have skin. Fish also are covered in a layer of mucus just as we are covered in hair. The scales are produced from the mesoderm and dermis and are made from the same cells that produce hair, skin, and nails. Their skin also focuses on keeping their body warm since the fish is cold-blooded.

The Blue Whale's skin acts very similar to a humans skin but it is much thicker and covered a much larger surface. They are mammals but swim in cold waters so their skin is thick to aid in temperature control.

Disease of the Integumentary System

A disease of the integumentary system in Acne.

Acne is blocked skin follicles that lead to oil , bacteria , and dead skin buildup in your pores. Your pores then swell and create what is commonly known as a whitehead. Common acne can be caused by dirt and debris on your face not getting washed off properly, or other factors like hormones. Your genetics can lead you to have acne like cystic acne .

in Animals Some lizards, like bearded dragons, will get shed skin and oil stuck in their pores. Hairless cats may also have acne.
