The Immune system
The immune system organs
Active immunity is when it exposes the body to an antigen to generate an adaptive immune response. For example, HAV gives rise to a natural active immune response usually leading to lifelong protection.
A Antigen is a toxin that includes an immune response in the body.
Passive immunity Is when it provides antibodies to protect against infection. Passive immunity is usually classified as natural or acquired.
Antibodies are recruited by the immune system to identify and neutralize objects like bacteria and viruses.
More about antibiotics
Antibiotics are effective against bacteria but not against viruses. Why though? Well, antibiotics block metallic pathways in the bacteria and antibiotics are used to treat viral diseases like strep of the flu because they are ineffective. But sense viruses do not posses a cell wall, they don't get affected by antibiotics.
Disorders
Swollen glands. Lymph nodes are small, bean-shape structures that produce and store cells that fight infection and disease and are part of the lymphatic system. When that swell up, some signs/symptoms are tenderness or pain when you press on them, there red, and it's kinda of a lump. To treat this, you can take over-the-counter medicine like tylenol or you can apply a warm, wet towel to the area.
