1
Q
What functions are electrolytes responsible for in the body?
A
- Maintaing balance of water
- Maintain balance of blood pH
- Moving nutrients into/out of cells

2
Q
What two receptors does the body use to inform the brain we are hypovolemic?
A
- Osmoreceptors
- Chemoreceptors
3
Q
The lamina terminalis plays what role in water regulation within the body?
A
Thirst response
4
Q
How does the body respond to a rise in serum osmolality?
A
Release of antidiuretic hormone (vasopressin) to have the kidneys begin reabsorbing water?
