EXPLAIN THE BASIC FUNCTIONS OF THE HUMAN IMMUNE SYSTEM, INCLUDING SPECIFIC AND NON SPECIFIC IMMUNE RESPONSES

Antibody

A blood protein produced in response to and counteracting a specific antigen. Antibodies combine chemically with substances that the body recognizes as alien, such as bacteria, viruses, and foreign substances in the blood.

Antigen

A toxin or other foreign substance that induces an immune response in the body, especially the production of antibodies

Inflammation

Inflammation is a process by which the body's white blood cells and substances they produce protect us from infection with foreign organisms, such as bacteria and viruses.

Fever

Fever, also known as pyrexia and febrile response, is defined as having a temperature above the normal range due to an increase in the body's temperature set-point.

Antibiotic Resistance

Vaccine

A substance used to stimulate the production of antibodies and provide immunity against one or several diseases, prepared from the causative agent of a disease, its products, or a synthetic substitute, treated to act as an antigen without inducing the disease
