Blood is made of three specialized elements called erythrocytes (red blood cells), leukocytes (white blood cells) and platelets that are suspended in a complex liquid called plasma. The constant flow of blood keeps the cells evenly distributed in the plasma.eukocytes or white blood cells perform a variety of functions related to immunity. These cells are the primary cells responsible for the defense against foreign invaders into the body such as viruses and bacteria. Platelets Platelets are the cellular elements in blood that help to form blood clots.
Specific immunity is a complement to the function of phagocytes and other elements of the innate immune system. In contrast to innate immunity, specific immunity allows for a targeted response against a specific pathogen.Only vertebrates have specific immune responses. Two types of white blood cells called lymphocytes are vital to the specific immune response.Lymphocytes are produced in the bone marrow, and mature into one of several subtypes. The two most common are T cells and B cells. An antigen is a foreign material that triggers a response from T and B cells.pecific immunity is a complement to the function of phagocytes and other elements of the innate immune system.
