Physiology Part 4 Flashcards
metabolic acidosis
diarrhea, ketosis, renal dysfxn
body’s compensation for metabolic alkalosis
hypoventilation
keep lungs expanded, decrease surface tension
lipoprotein
made by pneumocytes aka type 2 alveolar cells
surfactant
hyaline membrane disease
no surfactant
what happens to lung pressure when diaphragm contracts?
decreases pressure -> inspiration
Herrin-Breuer reflex in bronchi
prevents over-stretching of lungs
Apneustic center
prevents turn off of inspiratory center
CO2 enters blood and causes O2 to dissociate from hemoglobin
Bohr effect
CO2 combines with hemoglobin -> more bicarbonate ions
Haldane effect
Rathke’s Pouch
Anterior pituitary (adenohypophysis)
Embryo dev of posterior pituitary (neurohypophysis)
neural ectoderm
Vasopressin and Oxytocin
posterior pituitary
GH/Somatotropin, TSH, LH, and FSH
anterior pituitary
milk let-down/ uterine contraction
oxytocin
