where are osteon found
compact bone / lamellar bone
osteocyte found what
lacuna
what do club cells do
secrete SURFACTANT, enzymes that DETOXIFY inhaled xenobiotic compounds, antimicrobial peptides and cytokines
chemosensory brush cells
DNES (diffuse neuroendocrine system) small granule cell (detect irritants)
type I pneumocytes/ alveolar cells
REMOVE SURFACTANT and small particulate contaminants party though pinocytosis
contains SIMPLE SQUAMOUS cells which are thin and thus good for diffusion
