The immune system is the part of the body that protects from harmful bacteria and infections. It uses different features such as lymph nodes, tonsils and the spleen to filter all things bad for the body out of you in different ways. Without this system, the body would have no immunity to infections causing more severe reactions to symptoms.
Parts of the Immune System
Lymph Nodes
Lymph nodes are located throughout the entire body and are used to filter out and trap foreign particles within the body. They contain many white blood cells that are caled lympocytes and macropages.
Lymph Ducts
Lymph ducts carry lymph fluid through the body to Lymph Nodes.
Lymphatic Fluid
This is the fluid that travels throughout the lymphatic sytem. Lymphatic fluid picks up bacteria it encounters in the body and transports it to lymph nodes in order to be destroyed.
Spleen
The spleen can be considered a very large lymph node, as it works primarily as a blood filter. The spleen stores around 30% of all red blood cells as well as lymphocytes.
Thymus
The thymus produces thymosin, a hormone which promotes the development of antibodies and T-lymphocytes, also known as T-cells.
Tonsil
Tonsil are made up of lymphoepithelial tissues and is located in the back of the throat. It is your bodies first line of defense against airborne pathogens.
Bone Marrow
Bone marrow produces lymphocytes which fight infections.

How smoking affects the Immune System
Tobacco smoke has very serious affects on the Immune system. Tobacco causes T-cells, which are used to attack infections, to become unresponsive. When these T-Cells are destroyed, infections and other types of illnesses last much longer and are more severe. Smoke also raises likely hood of pneumonia and influenza. Not only that, but smoking leads to cancer cells in the lungs which, because of the destruction to the T-cells, is more rapidly able to grow.
