Virology (1930s, discipline of ECM (100,000x) allowing vision of the first virus (Yellow Fever)
Immunology-1960s
immunity is vindication and defense against dangerous microbes or their toxins. Vaccines are used to roseola this defense response and prevent any further contagion by generating a host defense response. An innate immunity is present at birth and consist of anatomical barriers (skin which is fat and mucous membranes which are thin), lysozymes that lyse bacteria and are found in high concentration of tears, the stomach gastric acid of pH1-2, and cilia which use a sweeping motion in the lungs to brush remote trapped bacteria in mucous membranes…this can be slowed in cold temperatures increasing chances of pneumonia.
Serology is the study of serum usage. serum is plasma without the components of clot, which can be separated by centrifugation. serum antibodies are clues to infections that a person has already had. A diagnostic test detects the antigen via the antibody reaction and are known as serological test.
Antigens and antibody reactions have a very high specificity allowing these test to testify the results of the infection.
Two major areas of Immunology are Molecular immunology (protein chemistry) and cellular immunology. cellular immunology contains lymphatic system (drain tissue fluid into lymph nodes), phagocytosis, and lymphokines (chemical mediators of the cell arbitrate immune response) which are mostly produced by thymus delay hypersensitivity cells Tdh.
Adaptive Immune System (disease fighting mechanism against microorganisms and neoplasm cells)
Two branches: Humoral Immunity and Cellular
Humoral Immunity is antibody mediated with five different antibody classes (IgM,IgA,IgD,igG,igE)
Ig=immunoglobulin…da Gamma globulin is found in...If you want to get a full essay, request it on our website: Orderessay
