normal blood glucose level-
70-110mg/dl (100 mg/dl or less)
Kupffer cell
Resident liver macrophages & play a critical
glial cells

metabolic support.
-ex: astrocytes, ependymal cells, oligodendrocytes, Schwann cells

s/sx: polyuria (urine) & polydipsia (thirst)
filtration
Fluid filtered from blood vessels into nephron tube; mostly occurs in kidneys for smaller particles
Opsonization (aka immune adherence
The enhancement of phagocytosis by coating microorganisms with certain serum proteins (opsonin)

Cells that line alveoli
Secrete surfactant.
Decrease surface tension.
Increase lung compliance.
Prevent atelectasis (collapse of the lung) at the end of expiration To facilitate recruitment of collapsed
airway
Surfactant
Decrease surface tension Helps prevent the alveoli from collapsing
FEV and FEV1,
FEV
Percent of air that is forcefully exhaled in a certain time frame
FEV1 Percent of air that can be exhaled in 1 second
Erythropoietin
A hormone produced & released by the kidney that stimulates the production of RBC’s by the bone
marrow In response to low O2
