Lymphoid

1. 1Primary Lymphoid organs: [blank_start]bone marrow[blank_end] and [blank_start]thymus[blank_end]

2. 2Cells:
   [blank_start]lymphocytes[blank_end] - precursors in bone marrow; [blank_start]B cells[blank_end] - memory and plasma cells; [blank_start]T cells[blank_end] - memory and helper or cytotoxic
   [blank_start]accessory cells[blank_end] - APCs - [blank_start]dendritic[blank_end] cells; [blank_start]macrophages[blank_end]
   [blank_start]effector cells[blank_end] - [blank_start]cytotoxic[blank_end] T cells; [blank_start]helper[blank_end] T cells; [blank_start]plasma[blank_end] cells

   nodules - lymph node - in-line lymph filter;
   [blank_start]cortex[blank_end] - [blank_start]inner[blank_end] - T lymphocytes, lymphoid nodules; [blank_start]outer[blank_end] - undefined borders, very few nodules
   [blank_start]medulla[blank_end] - [blank_start]cords[blank_end] - lymphocytes, plasma cells; [blank_start]sinuses[blank_end] - macrophages and reticular cells
   [blank_start]MALT[blank_end] - IgA secreting cells, APCs, B cells, helper T cells; diffuse and solitary nodule; peer's patches in lumen; tonsils - [blank_start]palatine[blank_end] - stratified squamous, crypts; [blank_start]pharyngeal[blank_end] - ciliated pseudo stratified columnar, no crypts; [blank_start]lingual[blank_end] - stratified squamous, one crypt

4. 4Organs:
   [blank_start]thymus[blank_end] - lymphoepithelial origin; [blank_start]cortex[blank_end] - thymocytes (T cell precursors), epithelial reticular cells, macrophages; [blank_start]medulla[blank_end] - differentiated T lymphocytes, epithelial reticular cells; thymic-blood barrier
   [blank_start]spleen[blank_end] - largest lymphoid tissue; in-line blood filter; erythrocyte destruction; blood circulation; [blank_start]capsule[blank_end] - dense irregular CT; hilum; splenic pulp - [blank_start]white[blank_end] - PALS, lymphoid nodule; [blank_start]red[blank_end] - splenic cords, sinusoids; [blank_start]circulation[blank_end] - [blank_start]closed[blank_end] = capillaries drain into sinusoids; [blank_start]open[blank_end] = arterial blood pass through cellular space and into sinusoids; [blank_start]return[blank_end] = sinusoid to red pulp vein to trabecular vein to splenic vein

5. 5Antibodies:
   [blank_start]IgG[blank_end] - most abundant; cross placenta; activate complement system; act as opsonins
   [blank_start]IgA[blank_end] - secretions; muscous membranes; prevents pathogen attachment
   [blank_start]IgM[blank_end] - first in antigen response; membrane-bound on B cells; agglutination and complement activation
   [blank_start]IgE[blank_end] - low concentrations; mediate allergic reaction; receptors on mast cells and basophils; induces degranulation
   [blank_start]IgD[blank_end] - activated B cells

7. 7[blank_start]innate/natural immunity[blank_end]:anatomic barriers - intact skin; muscous membrane
