Renal System Physiology

QuestionAnswer
Glomerular Filtration Rate (GFR) Produced by glomeruli; 180 liters per day
Glomerular Filtration Passive process; fluid passes from glomerular capillary to glomerular capsule
Tubular Reabsorption Moves filtrate back into blood; leaves salt-water and waste in lumen
Reabsorption Carriers Actively reabsorb solutes at a higher rate
Tubular Secretion Kidneys rid blood of unwanted substances like creatinine and ammonia
Afferent Arteriole Radius Decrease Pressure and filtration rate decreased
Afferent Arteriole Radius Increase Pressure and filtration rate increased
Efferent Arteriole Radius Decrease Pressure and filtration rate increased
Efferent Arteriole Radius Increase Pressure and filtration rate decreased
Increased Blood Pressure Glomerular capillary pressure and filtration rate increase
Decreased Blood Pressure Glomerular capillary pressure and filtration rate decrease
Antidiuretic Hormone (ADH) Affects urine colume; responsible for fluid retentiion
Aldosterone Produced by adrenal cortex; increases soduim reuptake and potassium secretion
Increased ADH Urine increases; potassium is more concentrated
Increased Aldosterone Urine decreases; sodium and water-reabsorption increases; potassium secretion increases

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.

To see how well you know the information, try the Quiz or Test activity.
