Largest secondary lymphoid organ

where T cell recirculate or what secondary lymphoid organs it recirculate here is the tolerance to ingested antigens

important for rhe development of tolerance to ingested Ag

IgA production and lymphocyte recirculation

what cell is in the marginal zone?

what cell is in the PALS

PALS

T cells surrounds artery

Trapping site of the pathogen or waiting area of the lymphocytes

it is where adaptive immunity is made

center of antigen-independent lymphopoiesis

it is where B cells maturation withGALT

Bone marrow source of ________ cells

source of PROGENITOR cells

DSE WHICH HAS PANMYELOSIS AND PANCYTOSIS

DSE W/O STEM CELL; LESS AFFECTED LYMPHOCYTES

DSE INFILTRATE BONE MARROW AND TRANSFER TO SPLEEN

IT IS FROM BONE MARROW WHICH CONTROL IMMUNE SYSTEM

T cells develop their identifying characteristics (3 weeks maturation)

develop their identifying characteristics (3 weeks maturation)

T cells develop their identifying characteristics ( ? weeks maturation)

INCREASE SUSCEPTIBILITY TO INFECTION, NEOPLASM AND AUTOIMMUNE DSE AMONG OLDER PEOPLE

Immune senescence BEC IT SHRINKS AS WE AGED

HOW MANY % of cells die in the thymus

it is where exercises CONTROL over the immune system

THESE TWO MAINTAINS THE SECONDARY LYMPH

occurs but it is strictly DEPENDENT on Antigenic Stimulation, IF NO AG IT IS DORMANT

ARE UNSTIMULATED PRIMARY B CELLS

ZONE WHERE DENDRITIC CAN BE SEEN

Major organ for particle CLEARANCE

INCREASES WHEN THERE IS INFECTION

LYMPH NODES IS Generation of________ is the primary function

IS Generation of B-CELLS is the primary function

Rich in mature T cells

Most frequently SAMPLED lymphoid organ

Most circulating lymphocytes – T cell

MALT

NON VITAL ORGANS
