05: Misc Flashcards
Too much (aldosterone/ADH) secretion is likely to cause hypokalemia.
Aldosterone (too much ADH will significantly reduce tubular flow and K secretion)
Blockage of the distal tubule Na+-Cl- cotransporter will (increase/decrease) K secretion in distal nephron.
Increase (increase tubular flow due to lower reabsorption)
Inceased delivery of non-reabsorbable anions to the distal nephron will (increase/decrease) K secretion in distal nephron.
Increase
T/F: A 1 mM increase in extracellular K conc will have the same effect on membrane
potential as a 1 mM decrease in intracellular K+ conc.
False
A few days after doubling the usual salt intake of a person, the body ideally readjusts to increased amount by balancing:
Excretion with ingestion (the ingested and excreted amount of Na will be equal);
In this case, the kidney excretion of Na will double
T/F: You’d expect to find an alkaline urine in chronic respiratory acidosis.
False - you wanna save/make bicarb to compensate for the acidosis
T/F: The osmolality of the tubular fluid remains constant along the proximal tubule.
True
Most body water is in the (extra/intra)-cellular space. And the concentration of protein is higher in (cells/plasma).
Intracellular;
Cells
T/F: Intravenous infusion of isotonic saline decreases plasma oncotic pressure.
True
T/F: Usually more than half of body mass consists of water.
True
(One/several) nephron(s) drain(s) into a (one/several) collecting duct(s).
Several; one
