POINT!
| With an increase/a decrease in the synthesis, secretion, and blood concentration of vasopressin (ADH), plasma osmolarity decreases/increases. |
| With an increase/a decrease in the synthesis, secretion, and blood concentration of vasopressin (ADH), plasma osmolarity decreases/increases. |
With an increase/a decrease in the synthesis, secretion, and blood concentration of vasopressin (ADH), the number of water channels (in the tubule) increases/decreases, which increases/decreases the water reabsorption (from the tubule). The plasma osmolarity-decreasing effect of water reabsorption becomes stronger/weaker, and plasma osmolarity decreases (diluted, hypotonic)/increases (concentrated, hypertonic).
