Osmotic Balance Challenges by Habitat
This video presents the same text shown beside it, spoken and on screen. It adds nothing the text does not say.
State
A freshwater osmoregulator gains water and loses solutes to its dilute surroundings; a marine osmoregulator loses water and gains solutes to its concentrated surroundings.
Show
In a hospital, IV fluid osmolarity is matched to blood plasma to avoid triggering this same solute shift in patients.
Watch for
A terrestrial animal faces a distinct challenge — water loss to dry air, not liquid.
