secreted from posterior pituitary-distal and collecting-effects:increased reabsorption of water
Renal Calculi (nephrolithiasis)
crystal aggregation in kidneys collecting system,>men,hereditary.Causes=immobilization,meds,dehydration,cns disorders,gout,hyperparathyroidism-made of calcium oxalate and calcium phosohate
Reffered pain
pain originates in a region other then where it is felt
Glucose
is almost completely reabsorbed in the proximal tubule-maintained until 180mg/dL-Type 1DM(so much sugar enters,reabsorption becomes inefficient=osmotic diuresis
Distal/collecting tubules
baroreceptors monitor osmolarity of filtrate-absorb(H2O,Na++,HCO3)-secrete -low osmolarity(urea,K+,H+,some drugs)
Renin angiotensin system
renin released from kidneys due to low pressure-acts on angiotensin-produces angiotensinI.then converted in lungs to angio II by ACE-takes 20 mins
Visceral pain
inflammation,distention,ischemia-transmits pain signals from veseral afferent nerve fibers back to spinal cord-DIFFUSE,DULL or CRAMPY,tachu,n/v, diaphoresis
