Question 3

Answer 3

Question 4

Osmolality

Answer 4

This describes the concentration of solutes in a liquid.

Question 5

Dipsogenic Signal

Answer 5

Physiological factors such as high osmolality or low blood pressure which prompt sodium and water appetite.

Question 6

Baroreceptors

Answer 6

Specialized nerves that can sense change in pressure in the heart or blood vessels.

Question 7

Hypo-osmotic

Answer 7

A solution with a lesser concentration of solutes.

Question 8

Answer 8

Gastric emptying rate describes the rate at which fluids and their contents pass through the stomach via the pyloric sphincter and into the small intestine.

Question 9

Convection

Answer 9

Question 13

Urine Specific Gravity

Answer 13
