RAAS

QuestionAnswer
Interstitial fluid has no proteins, indirectly regulated through the plasma, Na+, Cl-, and Bicarbonate ions
Edema excess fluid in the interstial fluid
Plasma directly regulated, has plasma proteins
Intracellular fluid accounts for how much of body fluids? 2/3
Extracellular fluid is composed of interstitial fluid, plasma
Extracellular fluid accounts for how much of body fluids? 1/3
Intracellular fluid major ions are K, phosphates, proteins
Extracellular fluid major ions are Na, Cl, Bicarbonate
What flows freely in the extracellular fluid? electrolytes, water
Regulation of volume of ECF is important for long-term control of _____ ______ salt balance
The kidneys produce _____ renin
The liver produces _____ angiotensinagen
Angiotensin I is converted to angiotensin II via _____ ACE
Adrenal glands secrete _____ aldosterone
The four effects of angiotensin II are vasoconstriction, increase aldosterone release, promotes thirst, release of vasopressin (ADH)
The effects of aldosterone are Reabsorption of Na, excretion of K
The types of natriuretic peptides are atrial natriuretic peptide and brain natriuretic peptide. decrease Na reabsorption.
Five effects of natriuretic peptide are decrease Na reabsorption, inhibit RAAS, inhibits sympathetic nervous system, vasodilation, relax mesangial cells.
Decreased plasma volume is detected by what receptors? left atrial volume receptors
Stimulation of left atrial volume receptors results in stimulation of hypothalamus to increase thirst and ADH release.
Increase in plasma osmolarity is detected by hypothalmic osmoreceptors
Stimulation of hypothalmic osmoreceptors leads to increase vasopressin and increase thirst
Vasopressin causes arteriolar vasoconstriction, increase absorption by the kidneys

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.
