What are the five systems functions?
The five systems functions are:
- Acts as a receptor for touch, pressure, pain, heat and cold
- Regulates the temperature in the body
- Protects the body against dehydration, sunburns, infection and other problems like that
- Generates vitamin D through exposure to ultraviolet light
- Store water, fat and vitamin D
What is the system's organ tissue ???
What is a system's organ tissue ???
I will show you two layers of the skin tissue:
Epidermis and Dermis.
The Epidermis is the first layer, and the Epidermis also has layers! The first layers
is dead skin cells called the "Startum Corneum", and the last layer produces more cells by undergoing continuous cell division called the "Startum Germinativum". The Epidermis protects us, but it is slightly acidic.It is also made of epithelial cells with no blood (and avascular).
About 30,000 and 40,000 dead skin cells take off of our skin PER MINUTE!
The Dermis is the second layer and it is a true skin made of connective tissue (it is vascular).
It does a lot of things such as :
Contains lots of sensory cells (heat, cold, pain and pressure)
Blood vessels regulate the body's temperature (expand or contract)
Has sebaceous glands to lubricate, protecte and make the skin waterproof
Also has sweat glands (cools, protects) and Colagen and Elastin to immune the cells
Three injuries for this system...
I chose acne because I can have this problem. This problem happens when you are about 14 years old, the time of puberty.
Acne vulgaris is a long-term skin disease that occurs when hair become clogged with dead skin cells and oil from the skin. Acne is characterized by areas of black heads, white heads, pimples, greasy skin and may result in scars. It can mean that you are anxious or that you have a problem.
Genetics is thought to be the cause in 80% of cases. The role of diet and cigarette smoking is sometimes one of the things that can cause acne. Even if you are never under the sunlight, you can have acne too. Acne primarily affects skin with a greater number of oil glands, including the face, upper part of the chest, and back. During puberty acne is common, but with special medical treatments you may not have acne. Excessive growth of the bacteria, which is normally present on the skin, is often involved.
You can use special treatment such as creme or shampoos.
A rash changes the skin (its color, appearance, or texture such as becomes warm, bumpy, chapped, dry, cracked or blistred, swell, and may be painful.It may be localized in one part of the body, or affect all the skin.Rash can be between 5 to 20 days, and it classically starts at the head.
It can be from anxiety, allergies or skin contact with irritant
(like food, dies, medicines, insect, metal...),Exposure to the sun (sunburn), frictions from the chafing of the skin or poor personal hygiene.
You can use creme such as hydrocortisone, or ask your doctor.
How can I get rid of a blister ?
The time for a blister to heal depends of the location, and the size of the area.
Protecting the blister from abrasions or additional shearing will help to keep the blister intact. Blister can occasionally infected, but it should be prevented by a good hygiene, and treated if necessary.
