An antigen is a substance which triggers an immune response in an organism. This can be either a foreign substance, such as a pathogen, or a specific part of the host organism (in this case this is an autoimmune response). The presence of an antigen activates a specific part of the immune system, called antibody. Each antigen has a specific antibody, which is tailored by the immune system accordingly. More specifically, the antibody has a specific structure, called paratope, which is complementary and binds like a key to a specific structure of the antigen, called epitope.
When you inhale and exhale, you actually breathe. When you inhale, your intercostal muscles between ribs and diaphragm contract. This increases the space in chest cavity so your lungs can expand and the air enters the lungs. When you exhale, intercostal muscles and diaphragm relax reducing the space in the chest which leads to removing the air from the lungs.
