Which statement about aldosterone is false?

(1) It is a major steroid (mineralocorticoid) hormone secreted by the kidney.

(2) It promotes the reabsorption of Na+ in the late distal tubule and the cortical region of the collecting duct.

(3) It stimulates the secretion of K+ from the peritubular blood into the distal tubule.

(4) Without it, no K+ is ever excreted in the urine.

Which statement about the glomerular filtration rate (GFR) is false?

(1) The GFR averages approximately 180 L per day

(2) The GFR will increase during fight-or-flight situations due to the vasodilation of afferent arterioles.

(3) A decrease in GFR results in a decrease in the total urine output.

(4) Renal autoregulation maintains the GFR at a relatively constant rate despite fluctuations in the mean arterial blood pressure.
