Lymphoid System Flashcards
The most heavily produced type of antibody that is very labile and can be seen in body secretions.
Immunoglobulin A
Lymphoid organ responsible for producing the hormone thymosin
Thymus
[3] Part of cellular immunity.
Nk cells, T helper cells, and Plasma cells
Part of the thymus responsible for secreting chemical signals that guides the development of T cells.
Hassal’s corpuscle
Antibody that has the largest molecular structure having 10 binding sites. Because of this, action of this antibody shows agglutination.
Immunoglobulin M
Part of the thymus where T cells that react with self-antigens are culled or lysed.
Medulla
Heavy-staining part of the thymus where numerous pre-T cells aggregate.
Cortex
Splenic pulp responsible for recycling hemoglobin from senescent erythrocytes.
Red pulp
Antibody that is known to be able to cross the placenta, which allows the mother to support the immune system of the fetus.
Immunoglobulin G
Consist of the structures and cells that protects the organism against invasion and damage by the microorganism and foreign substances.
Immune system
[4] Organs of immune system
- Thymus
- Lymph nodes
- Spleen
- Tonsils
Any substance that elicit response from the host.
Antigen
Also called immunoglobulins.
Antibody
Are plasma glycoproteins that interact specifically with antigenic determinants.
Antibody
[5] Types of Immunoglobulins
- IgG
- IgM
- IgA
- IgE
- IgD
[3] Free cells of the immune system.
- B lymphocytes
- T lymphocytes
- Antigen presenting cells
Largest lymphoid organ in human circulatory system.
Spleen
[2] Splenic pulp
- White pulp
- Red pulp
Forms a ring (Waldeyer’s ring) underneath the epithelium around the entrances to the respiratory and digestive passages.
Tonsils
Most of this organ are partially encapsulated by dense irregular connective tissue capsule.
