The Integumentary System

The epithelial cell is a very important part in your body. Its function is to protect the body but it can also malfunction. When they malfunction it can cause acne, dry skin, eczema, cellulitis, sun damage, psoriasis, rashes, and skin cancer to appear on the skin. The epithelial cell is part of the integumentary system. The integumentary system includes the skin, hair, and nails. This is a little bit about the epithelial cell.
The epithelial cells are part of the integumentary system. The integumentary system covers the surface of your body. The integumentary system does thermoregulation; this is the evaporation of sweat and the regulation of blood flow to the dermis. The cutaneous sensation, in the integumentary system, are sensations like …show more content…
The epithelial cells are contiguous, this means that they are attached to one another. The epithelium is an animal tissue that covers the body. The epithelium acts as a barrier between the outside world and the rest of the body. Also, the epithelium is semi permeable, so it is capable of letting certain molecules through while excluding other molecules from entry. The epithelial cells do the three junctions, anchoring junctions, tight junctions, and gap junctions. The anchoring junctions make the tight association of the epithelial cells. This is to resist stretching so that forces don't pull the cells apart. Tight junctions plug up the space between adjacent cells. Gap junctions allow passage of molecules, but it does it in a regulated way. This allows cells, such as muscle cells and nervous tissure to communicate and coordinate their activity. The epithelial cells have strong adhesion to prevent from fluid loss. These cells are constantly replacing themselves from the basal layer. These are some of the structure and functions of the epithelial …show more content…
One that is very common is acne. This is caused by the malfunctioning of oil glands which are under the skin. The pores of the skin are connected to oil glands underneath by small tubes called follicles. When glands malfunction it clogs the follicles and causes acne to appear on the skin. Dry skin is another very common skin condition. It is characterized by not having the appropriate amount of water in the epidermis. Symptoms of dry skin are skin tightness and itching. Eczema is a type of dermatitis called atopic dermatitis. This is characterized from dryness of skin with itchiness and rashes on several parts of the body. The spreading of a bacterial infection of the skin and tissues beneath the skin is called cellulitis. It sometimes appears on parts of the skin that have been broken open like a surgical wound. It begins as a small area of pain and redness on the skin which spreads to surrounding tissues causing inflammation, redness swelling, warmth, and pain. Sun damage is caused by a long exposure to the sun. This can cause premature skin aging, skin cancer and other skin changes. Skin color changes caused by the sun are most common. Psoriasis is the scaling of the skin with visible swelling. It can be in many forms but most of them cause red, usually thick silver scales to appear on various parts of the body. Rashes are also a very common skin condition. They may be temporary in nature and may come
