Osmoregulation

Question 1

What is it?

Answer 1

Maintaining water levels in the body
-balance of salt and water concentrations in the body to keep constant osmotic pressure through the use of osmoreceptors and the endocrine system
-its a physiological process.

Question 2

Homeostasis

Answer 2

The regulation of the constant internal temperature in the body

Question 3

What must be maintained in the body to maintain homeostasis

Answer 3

-glucose
-temperature
-Co2
-salts
-water

Question 4

ADH (Antidiuretic hormone)

Answer 4

-released from the pituitary gland on response from osmoreceptors within the hypothalamus.
-increases permeability of the walls of the collecting ducts which causes more water to be reabsorbed by the kidneys via osmosis

Question 5

Hypothalamus

Answer 5

-detects change in water content via osmoreceptors and controls regulation of water levels in the body

Question 6

Too little water in blood (hypotonic)

Answer 6

1.Hypothalamus- detects water levels
2.Pituitary gland- releases ADH
3.More water reabsorbed by kidneys
4.Less water lost in urine
5.Blood water levels returns to normal

Question 7

Too much water in blood (hypertonic)

Answer 7

1.Hypothalamus- detects water levels
2.Pituitary gland- releases ADH
3.Less water absorbed by kidneys
4. More water lost in urine
5.Blood water levels returns to normal
