Question

A 0.1 Osm plasma sample would

A. stimulate the action of osmoreceptors.
B. be hypertonic to the cells.
C. stimulate an increase in blood volume.
D. inhibit the release of antidiuretic hormone.

Answer 1

A 0.1 Osm plasma sample would be hypotonic to the cells.

Step-by-step explanation:

A 0.1 Osm plasma sample would be hypotonic to the cells.

The osmotic pressure of the plasma, also known as oncotic pressure, is the primary stimuli for the release of antidiuretic hormone (ADH). If the plasma is hypertonic, then there is increased secretion of ADH. If the plasma is hypotonic, the secretion of ADH is suppressed. Since a 0.1 Osm plasma sample is lower in osmolality, it would be hypotonic to the cells.
