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
beta cells of pancreas
insulin
alpha cells of pancrease
glucagon
Parathyroid hormone
calcium regulation
Zona glomerulosa,
Zona Fasciculata,
Zona Reticularis
GFR=Salty, Sweet, Sex
Glomerulosa=salt-mineralcorticoids (aldosterone)
Fasciculata=sweet=glucocorticoids (cortisol; regs sugar)
Reticularis=Sex=androgens (testosterone)
hormones of adrenal medulla
MEN ( medulla-epi and norepi)
starch digestion in the mouth
salivary amylase
chief cells
pepsinogen
G cells
gastrin
Parietal cells
HCL
Brunner’s cells
Duodenum
most food digestion
jejunum
Peyer’s Patches (lymphoid tissue)
ileum
Crypts of Lieberkuhn
Small intestine
cholecystokinin
gall bladder (bile released)
secretin, insulin, and glucagon
pancreas
Paneth cells and Taenia coli
colon
no teania coli, columns of Morgagnie
rectum
bile production; kuppfer cells; go to answer
liver
