What is Osmosis
|
Water movement to make concentrations equal.
|
|
Isotonic concentrations are__________.

|
What happens to the blood pressure as salt intake is increased?
|
Blood water is retained, then blood volume increases, then blood pressure increases.
|
|
Anhydrobiosis
|
A dormant state without water.
|
|
What are Osmoregulators?
|
They use energy for water uptake/loss to maintain osmolarity between a certain range.

What is Filtration?
|
Filtering of body fluids from capillary to nephron
