Protein that is produced by lymphocytes (white blood cells) and that attaches to a specific antigen. Antigen. Molecule on the surface of a pathogen that identifies it as a foreign invader to the immune system.Bacteria. Single-celled organism. Has a cell wall, cell membrane, cytoplasm.he white blood cells then produce antibodies to match the shape of the antigens. The antigens on the surface of pathogenic cells are different from those on the surface of your own cells. This enables your immune system to distinguish pathogens from cells that are part of your body.
Most blood cells are made in your bone marrow. They are constantly being made and replaced. How long a cell lasts before being replaced is called its lifespan. Your blood is made up of 4 components: red blood cells, white blood cells, platelets, and plasma. Blood Components Red blood cells (erythrocytes) Red blood cells carry oxygen from your lungs to your tissues. They also bring carbon dioxide back to your lungs. Red blood cells make up about 44% of your blood. The lifespan of a red blood cell is around 120 days. White blood cells (leukocytes) White blood cells fight infection and help you develop immunity to disease. They make up less than 1% of your blood. There are 3 types of white blood cells: granulocytes, monocytes, and lymphocytes. Each type has specific functions. There are 3 subtypes of granulocytes: Neutrophils, which help fight bacterial and fungal infections. Basophils, which are associated with immune responses, although their exact function isnât well known.
