video prior to the decrease in ADH
Prior to ADH decreasing (at baseline), we will make the assumption that the subject is in homeostasis with normal plasma and urine osmolarities (isotonic) and volumes.
video just after the increase in ADH
Step 1: Suppose that the synthesis, secretion, and blood concentration of ADH decreases.
The water channel-increasing effect of ADH decreases, thereby decreasing the number of water channels. This decreases the reabsorption of water by the kidney.
video showing the changes in plasma and urine after the increase in ADH
The ratio of Na+ to water entering the plasma due to reabsorption increases. This increases plasma osmolarity (hypertonic). Because a higher ratio of Na+ to water leaves the tubule due to reabsorption, the fluid remaining in the tubule has a lower osmolarity (hypotonic). Also, with a decrease in water reabsorption, there is more water remaining in the tubule. Overall, the urine becomes less concentrated (hypotonic) and higher in volume.
