Q

Organ responsible for cleansing the blood of waste product.
-Form urine and eliminate waste from the blood
-Balance substances entering and exiting the blood
-Regulate certain chemicals in the blood

Q

Where are the kidneys located?

A

-Against the posterior of the body, on either side of the spine
-Kidneys are retroperitoneal (between the peritoneum and back wall)
-Right and left quadrants respectfully
-Right kidney sits slightly lower than the left to account for the liver

Q

Responsible mainly for filtration of the blood
Nephron

A

Renal corpuscle

17
Q

Components of renal corpuscle:
1. Structure that holds the glomerulus
2. Web of capillaries that are responsible for filtering blood

A
  1. Bowman’s capsule (glomerular capsule)
  2. Glomerulus
18
Q

Responsible for reabsorption and secretion
*region of nephron

A

Renal tubule

19
Q

Components of renal tubule:
1. Collects fluid from the glomerulus
2.
3. Empties into a collecting duct

A
  1. Proximal convoluted tubule
  2. Loop of Henle
  3. Distal convoluted tubule
20
Q

Narrow tubes that carry urine from the kidney to the bladder
-Exit the kidney at the hilum
-Enter the bladder at an angle
-Lined bu a mucous membrane
-Mucous membrane is continuous to the bladder
-Smooth muscle lines the inner wall
-Peristalsis moves urine through the ureters

A

Ureters

21
Q

Storage receptacle for urine.
-Inner layer lined by mucous membrane
-Outer layer made up of muscle
-Elastic fibers allow for bladder to expand or contract
-Inner layer lies in rugae when empty

A

Urinary bladder

22
Q

Passageway for the elimination of urine.
-Lowest and last part of the urinary tract
-Urine exits through the urinary meatus
-Urinary sphincter is made of skeletal muscle
-Mucous membrane lining is continuous with ureters
-About 5x longer in men

A

Urethra

23
Q

What is the process of urine production and flow?
filtration, reabsorption, secretion

A
  1. Blood is forced into the glomerulus because of pressure in the capillaries
  2. Filtration takes place in the capillaries of the glomerulus
  3. Filtered fluid, or filtrate, then enters the renal tubule:
    -Filtrate flows into the proximal convoluted tubule first then makes its way through the loop of
    Henle and finally to the distal convoluted tubule
    -Distal convoluted tubule empties into a collecting duct – at this point, “filtrate” becomes “urine”
  4. Urine makes its way from the DCT to the calyces of the kidneys
  5. Calyces empty into the renal pelvis
  6. Urine exits the kidneys through the ureters
  7. Urine travels through the ureters via peristalsis
  8. Urine enters and is stored in the bladder
  9. Signals from stretch receptors in the bladder send an alert to the brain that the bladder is full
  10. Urine exits through the urethral sphincter and then through the urinary meatus
