Wonders of the Immune System

The most obvious part of the immune system is what you can see. For example, skin is an important part of the immune system. It acts as a primary boundary between germs and your body. Part of your skin's job is to act as a barrier in much the same way we use plastic wrap to protect food. Skin is tough and generally impermeable to bacteria and viruses. The epidermis contains special cells called Langerhans cells that are an important early-warning component in the immune system. The skin also secretes antibacterial substances.

Specific immunity are things that protect the body from specific pathogens. It includes the third line of defense. They include the lymphocytes (white blood cells) such as the macrophages, Tcells, and memory B cells. Acrophages gobble up the bacteria, while t cells actively kill it, and memory B cells remembers the antigen for a faster immune response in case the body is invaded by the specific bacteria again.

Nonspecific immunity are things that protect the body from various bacterias, viruses, and pathogens. These include the first and second line of defense, such as the skin, fever( body gets hot as an attempt to kill the pathogen).

The immune system is made up of a network of cells, tissues, and organs that work together to protect the body. The cells involved are white blood cells, or leukocytes, which come in two basic types that combine to seek out and destroy disease-causing organisms or substances.

When you get a vaccination, you are usually being given a dead virus, or a weakened virus that won't harm you. You body then develops antibodies to this virus. These antibodies circulate in your blood system, usually for the rest of your life or for a given period of time and give you immunity towards the live virus if you encounter it. Vaccination does not guarantee immunity. Natural immunity happens only after one recovers from the actual disease.

Autoimmune hepatitis is a chronic inflammatory autoimmune disease of the liver. It usually occurs by itself, but it can coexist with other autoimmune diseases. Fatigue is the most common symptom and other symptoms include an enlarged liver, jaundice, itching skin rashes, joint pain, and abdominal pain. These symptoms range from mild to severe and can lead to cirrhosis (scarring and hardening) of the liver and may eventually lead to liver failure.
