Biology 12:

Urinary System

the kid knee 100
THE KID KNEE! 100

Urine collects here in the kidney

  • Renal pelvis
  • Board
the kid knee 200
THE KID KNEE! 200

This artery carries blood to the kidney

  • The renal artery
  • Board
the kid knee 400
THE KID KNEE! 400

These carry urine from the kidney to the urinary bladder

  • Ureters
  • Board
the kid knee 600
THE KID KNEE! 600

This process carries urine down the ureter

  • Peristalsis
  • Board
the kid knee 800
THE KID KNEE! 800

These are located in the urinary bladder and trigger urination

  • Stretch receptors
  • Board
the kid knee 1000
THE KID KNEE! 1000

Trace a urea molecule and a glucose molecule from the renal artery to the urethra/renal vein

  • UREA: Renal artery, afferent arteriole, glomerulus, Bowmen’s capsule, PCT, LOH, DCT, collecting duct, ureter, urinary bladder, urethra
  • GLUCOSE: renal artery, afferent arteriole, glomerulus, Bowmen’s capsule, PCT, efferent arteriole, renal vein
  • Board
ephron s nephron 100
EPHRON’S NEPHRON! 100

This is a delicate ball of capillaries

  • Glomerulus
  • Board
ephron s nephron 200
EPHRON’S NEPHRON! 200

This structure starts in the renal cortex, goes into the renal medulla but goes back to the renal cortex

  • Loop of Henle
  • Board
ephron s nephron 400
EPHRON’S NEPHRON! 400

This the network of capillaries that are branched from the efferent arteriole

  • Peritubular capillaries
  • Board
ephron s nephron 600
EPHRON’S NEPHRON! 600

These 3 structures are only found in the renal cortex

  • Bowmen’s capsule, PCT and DCT
  • Board
ephron s nephron 800
EPHRON’S NEPHRON! 800

Many nephrons join to form one of these

  • Collecting duct

Board

ephron s nephron 1000
EPHRON’S NEPHRON! 1000

These parts of a nephron are thicker due to the abundance of transport proteins in the lining of the tubules

  • PCT, DCT and last portion of the ascending LOH
  • Board
making urine 100
MAKING URINE! 100

Pressure filtration occurs between these two structures

  • Glomerulus and Bowmen’s capsule
  • Board
making urine 200
MAKING URINE! 200

These _________ molecules make up the ________ inside the nephron

  • Small, filtrate
  • Board
making urine 400
MAKING URINE! 400

This molecule is required during the process of selective re-absorption, without it, re-absorption would not happen

  • ATP
  • Board
making urine 600
MAKING URINE! 600

These are an example of molecules that are reabsorbed that do not require ATP

  • Water, Cl- (they follow the Na+ as its being pumped out of the PCT)
  • Board
making urine 800
MAKING URINE! 800

Water passes through the ________ portion of the LOH by ___________.

  • Descending, osmosis
  • Board
making urine 1000
MAKING URINE! 1000

The filtrate in the descending LOH becomes “salty” for these reasons

  • - loss of water (osmosis) due to going into an hypertonic environment (the renal medulla)
  • Board
making more urine 100
MAKING MORE URINE! 100

The descending LOH is permeable to ____ and the ascending LOH is permeable to ____

  • Water, Na+
  • Board
making more urine 200
MAKING MORE URINE! 200

This molecule is necessary for tubular secretion to occur

  • ATP
  • Board
making more urine 400
MAKING MORE URINE! 400

Blood pH adjustments occur

  • DCT
  • Board
making more urine 600
MAKING MORE URINE! 600

If blood has a low pH what will happen to H+ and HCO3- re-absorption into the blood?

  • HCO3- absorption will go up and H+ will go down
  • Board
making more urine 800
MAKING MORE URINE! 800

The ascending LOH moves Na+ out of the filtrate by _______ and _______

  • Diffusion, active transport
  • Board
making more urine 1000
MAKING MORE URINE! 1000

Its necessary to use active transport to pump Na+ out of the filtrate in the ascending LOH for this reason.

  • The Na+ concentration in the filtrate is greater (compared to the Na+ concentration in the blood) at the bottom of the LOH, but lessens as it ascends the LOH. So Na+ requires pumps to move out of the filtrate as the gradient itself no longer enough
  • Board
yes more water 100
YES! MORE WATER! 100

Water re-absorption occurs the most in this portion of the kidney

  • Renal medulla
  • Board
yes more water 200
YES! MORE WATER! 200

In these portions of the nephron water is re-absorbed

  • Collecting duct, descending LOH and PCT
  • Board
yes more water 400
YES! MORE WATER! 400

ADH secretion from the ________, which is triggered by _________, and acts on the _______

  • Posterior pituitary, lower blood volume, collecting duct
  • Board
yes more water 600
YES! MORE WATER! 600

Higher levels of ADH do this to the volume of urine

  • Decrease it
  • Board
yes more water 800
YES! MORE WATER! 800

Alcohol does this to ADH secretion and as a result does this to urine volume

  • Inhibits, increases
  • Board
yes more water 1000
YES! MORE WATER! 1000

If blood pressure drops due to low Na+ levels this happens

  • Aldosterone is released from the adrenal cortex  causes an increase in Na+ re-absorption (and K + excretion) in the DCT  causes more water re-absorption in the collecting duct  less urine and increased blood pressure  aldosterone release stops
  • Board
i gotta go now 100
I GOTTA GO! NOW!! 100

Sodium retention occurs here in the nephron

  • Ascending LOH

Board

i gotta go now 200
I GOTTA GO! NOW!! 200

Coffee is a diuretic because is does this

  • Increases blood volume by causing water retention which increases pressure filtration  more urine
  • Board
i gotta go now 400
I GOTTA GO! NOW!! 400

Finding glucose in the urine indicates this

  • Possible diabetes; greater urine flows as less water is re-absorbed
  • Board
i gotta go now 600
I GOTTA GO! NOW!! 600

This molecule is maximally filtered and reabsorbed

  • Glucose
  • Board
i gotta go now 800
I GOTTA GO! NOW!! 800

Urea is made by the ______ but excreted by the ______

  • Liver, kidney
  • Board
i gotta go now 1000
I GOTTA GO! NOW!! 1000

How does the hypothalamus function in urine formation

  • Low levels of blood volume  cause the hypothalamus to secrete ADH  causes the posterior pituitary to release ADH into the blood  causes collecting duct to increase water re-absorption  increases blood volume so hypothalamus stops ADH production (NEGATIVE FEEDBACK)
  • Board
