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

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

important for rhe development of tolerance to ingested Ag

Major organ for particle CLEARANCE

LYMPH NODES IS Generation of________ is the primary function

Immune senescence BEC IT SHRINKS AS WE AGED

what cell is in the marginal zone?

T cells develop their identifying characteristics ( ? weeks maturation)

T cells develop their identifying characteristics (3 weeks maturation)

Rich in mature T cells

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

PALS

what cell is in the PALS

IT IS FROM BONE MARROW WHICH CONTROL IMMUNE SYSTEM

it is where B cells maturation withGALT

HOW MANY % of cells die in the thymus

ARE UNSTIMULATED PRIMARY B CELLS

INCREASES WHEN THERE IS INFECTION

Largest secondary lymphoid organ

T cells surrounds artery

THESE TWO MAINTAINS THE SECONDARY LYMPH

Most frequently SAMPLED lymphoid organ

ZONE WHERE DENDRITIC CAN BE SEEN

DSE WHICH HAS PANMYELOSIS AND PANCYTOSIS

DSE INFILTRATE BONE MARROW AND TRANSFER TO SPLEEN

Most circulating lymphocytes – T cell

Bone marrow source of ________ cells

DSE W/O STEM CELL; LESS AFFECTED LYMPHOCYTES

develop their identifying characteristics (3 weeks maturation)

NON VITAL ORGANS

it is where adaptive immunity is made

it is where exercises CONTROL over the immune system

center of antigen-independent lymphopoiesis

IS Generation of B-CELLS is the primary function

MALT

source of PROGENITOR cells

Trapping site of the pathogen or waiting area of the lymphocytes

IgA production and lymphocyte recirculation
