Dehydration Flashcards
What is controlled by the anti diuretic hormone?
The amount of water released from the collecting ducts to be retained by the body
Where is ADH released from?
The posterior section of the pituitary gland in the brain.
What does the hypothalamus monitor?
the composition of the blood as it flows past osmoreceptor cells in the brain, as well as receiving signals from receptors elsewhere in the body
What does ADH increase?
the permeability of the collecting duct to water, by upregulating production of aquaporins
When is ADH produced?
When an individual is dehydrated
How can water conservation be improved?
by having a longer loop of Henle
What does having a longer loop of Henle do?
Increases the salt gradient in the medulla, which means more water is reabsorbed by the collecting ducts and urine is concentrated
