Immune System Flashcards
The immune system is classified as a separate system from the hemoglobin system, however, most immune cells originate in the hematologic system.
Often, the study of allergies will go hand in hand because an allergic response is actually an immune response.
Immune system
Classified as a separate system from the hematologic system
Most immune cells have their origin in the hematologic system
Immune system
Human immune system
Body’s defense against invading microorganisms, harmful chemicals, and foreign bodies
The immune system is made up of two types of cells
B-cells and T-cells
B Cells are created and mature in the bone marrow
They get activated and produce antibodies that attach to the surface of the infectious agent.
T-cells identify infectious agents and directly attacking them.
Both T-Cells and B-Cells are lymphocytes.
Both T-Cells and B-Cells are lymphocytes.
Other type of white blood cells used by the body for protection include neutrophils, lymphocytes, monocytes,eosinophils, and basophils.

Antigens
Elicit an immune response in the body
Antigens that enter the body from the environment include:
- Inhaled macromolecules. For example, proteins on cat hairs that can trigger an asthma attack;
- Ingested macromolecules such as shellfish proteins that trigger an allergic response or a peanut allergy; and
- Molecules that are introduced beneath the skin such as on a splinter or in an injected vaccine.
Antibodies are immune system-related proteins called immunoglobulins.
Some antibodies destroy antigens directly; others indirectly by making it easier for white blood cells to destroy the antigen.
