Immune System

AIDS.gov


Function:
The function of the immune system is to keep your body safe from diseases, viruses, and bacteria that do enter the body.


Organs:
Thymus- The thymus teaches the T-cells during crucial childhood development.
Bone Marrow- The bone marrow contains and produces many blood cells.
Spleen- The spleen filters blood to keep bacteria away.
Tonsils-The tonsils contain bacteria and germs.
Lymph Nodes- Lymph nodes create lymphocytes which fight against bacteria before it goes back into your bloodstream.
Skin-The skin protects your body from outside invaders, such as germs and viruses.
Liver- The liver removes toxic chemicals.

Interactions: 

The immune system takes care of every organ. By this I mean the immune system attacks any viruses that are going after any part of your body. It has a strong relationship with the circulatory system. The immune system has the job of removing chemicals and bacteria from the bloodstream. Keeping these germs out of your circulatory system helps greatly. In addition to that, the immune system works with the lymphatic system to produce lymphocytes which fight against bacteria. The immune system has some connections with other systems that work to protect your body from diseases and bacteria.

The immune system reminds me a lot of airport security. This is due to the fact that both are very particular on what goes through. For example, not metal can go through the scanner for people, and the skin only allows certain things through your skin. Also, they make sure that everything is as it should be. The immune system makes sure there is no paranormal activity in certain organs because that is probably a disease or virus. Since airport security both patrols and makes sure only certain things can board the plane it reminds me of the immune system; protecting the body from bacteria and diseases.


Structure and Function(Skin):
Your skin is one of the most important parts of your body. You may not know it, but it works to keep you alive every second. Your skin is made up of three layers. The layer that is on the top makes up your skin tone and makes a barrier against water. The layer below has tissue to protect and sweat glands. The last layer has connective and subcutaneous tissue. The skin covers your entire body and has such a large surface area so it can carry out its function of protecting the body. The skin is full body protection. As well as that, monocytes are in the skin responsible for detection for diseases. The structure of the skin, mainly how large it is, really helps it perform its function.
