Highlight or circle an answer.

1. Ingestion of 20 oz water ( increases / decreases ) plasma osmolarity, which in turn ( increases /decreases ) plasma [ADH], leading to ( increased / decreased ) water retention by the kidney and increased water loss via the urine. This would be measured as an increase in urine volume and a(n) ( increase / decrease) in urine osmolarity.

2. Ingestion of 4 g of NaCl ( increases / decreases ) plasma osmolarity, which in turn ( increases / decreases ) plasma [ADH], leading to ( increased / decreased ) water retention by the kidney. This would be measured as an increase in urine osmolarity and a(n) ( increase / decrease ) in urine [NaCl].

Answer #1

Answer

1) Ingestion of 20 oz water decreases plasma osmolarity, which in turn decreases plasma [ADH], leading to decreased water retention by the kidney and increased water loss via the urine. This would be measured as an increase in urine volume and a decrease in urine osmolarity.

2) Ingestion of 4 g of NaCl increases plasma osmolarity, which in turn increases plasma [ADH], leading to increased water retention by the kidney. This would be measured as an increase in urine osmolarity and a decrease in urine [NaCl].
