Question

What is immunology?

Answer 1

The study of living beings, their origins, anatomy, morphology, physiology, behaviour, and distribution are characterised as biology. “It is a broad-ranging natural science with various unifying themes that unite it as a single, coherent topic. These fascinating features of biology are addressed by several sub-disciplines or branches of biology. Some branches of science are connected with other fields. The main branches of biology are genetics, immunology, microbiology, pathology, and biochemistry.

Complete answer:
Immunology is an area of biology that deals with the immune system, its components, biological processes, physiological functioning of the immune system, kinds, and disorders, among other things. Through many lines of defence, the immune system serves as a body's defence mechanism, safeguarding our cells, tissues, and organs against invading illness. The immune system recognises and destroys foreign antigens, such as dangerous bacteria and other disease-causing germs, in general. When our immune system is weakened or fails to operate, we develop numerous infectious diseases such as allergies, fever, and flu, as well as potentially fatal diseases such as cancer and AIDS.
Organ transplantation, bacteriology, cancer, virology, parasitology, rheumatic diseases, mental disorders, and dermatology are among areas where immunology is applied. The field of transplant immunology is concerned with the process of transplanting an organ from a donor to a recipient so that the recipient's body does not reject it.

Additional information:
The Innate Immune System is made up of cells and proteins that are always present and ready to attack infection-causing microorganisms. From the moment we are born, we have an innate immune system. The Adaptive Immune System, which is acquired during life, is essential to combat diseases that are not regulated by innate immune defences.

Note:
Immunology is defined as "the study of the immune system, including cell-mediated and humoral immunity, as well as immunological responses.". The immune system is made up of several cells and organs that protect our bodies against pathogens. The two types of immune systems that are characterised according to their ability to resist infectious pathogens: Innate immunity and adaptive immunity. The immune system's structure and functions can be studied using a variety of methods. which consists of: immunohistochemistry, ELISA. Antibodies generation, precipitation and immunoblotting etc.
