which body system produces proteins that help fight infections?
There are thousands of different B cells in our body, each of which produces a unique antibody. T cells develop in the thymus and help coordinate a rapid and tailored immune response to specific infectious organisms. Antibodies are proteins that are secreted from B cells. Antibodies help the immune system recognize foreign proteins that do not belong to the body. In doing so, they initiate an inflammatory response and clear the body of the invader. Neutrophils are the white blood cells that arrive first at the site of injury.
