Water balance and hormones Flashcards
Antidiuretic hormone (ADH) occurs in the..
distal tubule and collecting ducts
Antidiuretic hormone (ADH) cause kidney to increase..
water reabsorption
Antidiuretic hormone (ADH) causes the kidney to reabsorb water, because of this, urine becomes more concentrated. This leads to decrease urine output due to less urine =
less volume
Antidiuretic hormone (ADH) is present when a person lacks hydration, therefore taking the h2o from fluids the persons drinking. Due to this, the occurrence of Antidiuretic hormone (ADH) is a..
bad thing
Glomerulus needs what in order for filtration to take place?
High blood pressure.
High blood pressure = high blood volume
Low blood pressure and blood volume =
dehydration
Baroreceptors (BP receptors) detect low blood pressure. When it detects that the body has low blood pressure, it releases a hormone called..
aldosterone
Aldosterone (a hormone baroreceptors release) is produced in the adrenal glands (on top of the kidney). It increases Na+ reabsorption, this action is..
active
Aldosterone (a hormone baroreceptors release) increases water reabsorption, this action is..
passive
Aldosterone (a hormone baroreceptors release), increases water reabsorption. When there is an increase water reabsorption, it leads to increase b..
blood volume, which leads to an increased blood pressure
The pH of the body is..
7.3 - 7.5
The pH of the body is maintained by 3 mechanisms..
- A buffer system
- changes in breathing rate
- Kidney actions
One of the mechanisms that maintain the pH of the body is a buffer system. This buffer system maintain an acid base balance that prevent changes to pH by adding or..
removing H+ ions.
HCO3 + H H2CO3 H2O + CO2
One of the mechanisms that maintain the pH of the body is the breathing rate. An increase breathing rate..
generate more CO2 (More basic)
