The Lymphoid Organs Flashcards
(27 cards)
The most important function of the complement is to
Lyse bacterial cells and mammalian cells
Are the organs that are involced in the production of the immune cells
Lymphoid Organs
Sites of three important processes in Lymphoid Organs
Maturation
Differentiation
Proliferation
The growth of the cell from the time it is produced until such time that it is functional
Maturation
Specialization of the cell as to wether it
will become the cell of the innate immunity or the adaptive immunity or the activation of the cells of the adaptive immunity is also known as differentiation wether it becomes a T cell or B cell
Differentiation
Multiplication of the cells into many copies
of the same cells
Proliferation
Maturation is in what category
Primary
Sites of maturation
Primary
Thymus and Bone Marrow
Thymus is located along the
Sternum
where the T cell actually matures
Thymus
are subpopulation of lymphocytes which are actually produced in the bone marrow but they migrate early on to the thymus where they mature.
T cells
_________ which is the covering and it is where newly migrated cells go
Cortex of thymus
✓ ___________ is located towards the center and is
the area for newly formed cells which replaces the old ones.
Medulla of the thymus
Where all the blood cells are actually produced
Bone Marrow
Are the sites of differentiation and proliferation
Where the first encounter of the antigen takes place for the adaptive immunity
Secondary
sites of differentiation and proliferation in Secondary
Spleen
Lymph Nodes
MALT
Cutaneous Immune System
Two compartment/parts of the spleen
Red pulp
White pulp
Site of sequestration of RBC
Red pulp of spleen
Site of sequestration of phagocytes
White pulp of spleen
Lymph nodes are divided into
Cortex
Paracortex
Medulla
Why do lymph nodes swell during respiratory infection?
Because if the antigen will enter through the respiratory tract and your cells will encounter them, the nearest outpost is your lymph nodes
Site for B cells
Cortex of lymph nodes
Site for T cells and antigen presenting cells
Paracortex
Site for the macrophages
Medulla of lymph nodes
