What type of damage does the skin protect the body?
Disease: skin works to neutralise aggressors such as bacteria, viruses and pollution and prevent them for entering the body. UV rays: over-exposure to these harmful rays generates free radicals – aggressive molecules that cause cell damage. Pressure, blows and abrasion: skin recognises pain and alerts us to danger.
How does skin protect against bacteria?
Skin is a barrier that serves as one of the body’s first lines of defense against harmful microbes. Specialized immune cells within skin tissue help to fight invading organisms. Yet the skin hosts diverse communities of beneficial bacteria, collectively known as the skin microbiota.
What role does protecting the skin play in our health and survival?
Skin Protects Us The skin, along with hair and nails, is the protective covering of the body. In addition, the skin prevents germs from entering the body and damaging internal organs. Skin supports the life of all other body parts and plays a role in maintaining the immune system.

Why does the skin protect against infection?
The skin acts as an external barrier to bacteria, preventing infection and protecting the internal organs. The skin also protects the body from ultraviolet radiation using the pigment barrier formed from melanocyte cells found in the top of the papillary dermis and a protein layer found in the epidermis.
What are the four stages of the immune system?
This can be broken down into four stages: the lag, exponential, steady state, and declining phases. This is the time from initial antigen exposure to when antibodies are detected in the blood, and takes about a week. In this time, specialized B and T cells are activated by contact with the antigen.

What does your skin protect you from?
What does skin do? Skin has a lot of different functions. It is a stable but flexible outer covering that acts as barrier, protecting your body from harmful things in the outside world such as moisture, the cold and sun rays, as well as germs and toxic substances.
What is the 2nd line of defense?
If pathogens are able to get past the first line of defence, for example, through a cut in your skin, an infection develops. The second line of defence is a group of cells, tissues and organs that work together to protect the body. This is the immune system.
What are the 3 lines of defense?
In the Three Lines of Defense model, management control is the first line of defense in risk management, the various risk control and compliance over- sight functions established by management are the second line of defense, and independent assurance is the third.

What is the 1st 2nd and 3rd line of defense?
The first line of defense are the physical and chemical barriers, which are considered functions of innate immunity. … The third line of defense is specific resistance, which is considered a function of acquired immunity.
