what is the net gain of water per day
zero
insensible loss– skin
normal 350 exercise 350
insensible loss– lungs
normal 350 exercise 650
water lost in sweat
normal 100 exercise 5000
water lost in feces
normal 100 exercise 100
water lost in urine
normal 1400 exercise 500
total water intake from metabolism
200ml
activated first before RAAS
baroreceptor reflex
senses BP changes
macula densa
JG cells secrete
Renin
liver angiotensinogen is converted to angiotensin 1 by
renin
Aldosterone effects
Renal: inc Na reabsorption, inc K secretion, inc H secretion
side effects of high aldosterone
metabolic alkalosis; hypoK
what are the triggers for ADH secretion
Inc plasma osmolarity, dec blood volume, dec blood pressure
substance that is filtered, not reabsorbed and secreted
PAH
highest clearance (glucose, inulin, or PAH)
PAH
Estimates RPF and RBF (glucose, inulin, or PAH)
PAH
special renal cells: absorb Na and H20 and secrete K+
principal cells
special renal cells: absorb k and secre H
intercalated cells
special renal cells: secrete EPO
interstitial cells of peritubular capillaries
special renal cells: detects changes in sodium concentration in the distal tubule
macula densa
