Flashcards in Urology Deck (15):
1

Urinary Process Hormones

ADH and Aldosterone

2

Urinary Output during excessive hydration

In times of excessive fluid, the body will excrete a large volume of hypotonic dilute urine to conserve the necessary salts

3

Urinary Output during dehydration

Excrete a small volume of hypertonic concentrated urine

4

Collecting Duct

Determines how much salt is actually lost in urine
The osmotic gradient created in the earlier regions of the nephron allows the kidney control in the final concentration of the urine

5

Distal Tubule

Regulates concentration of K+ and NaCl
Helps control pH by reabsorbing HCO3- and secreting H+

6

Ascending Loop of Henle

Freely permeable to NaCl but not water
Assists in the control of water and salt concentrations

7

Descending Loop of Henle

Freely permeable to water but not NaCl
Assists in the control of water and salt concentrations

8

Proximal Tubule

Reabsorbs 75% of NaCl and water of filtrate
Nutrients such as glucose and amino acids are reabsorbed here unless their concentration is higher than the absorptive capacity

9

Bowman's Capsule

The sac that surrounds the glomerular capillaries

10

Glomerular Capillaries

Early portion of the nephron where the filtration process begins

11

Regions of Nephron

Renal corpuscle, Proximal tubule, Loop of Henly, Distal tubule and Collecting duct system

12

Medulla

Is divided into structures called renal pyramids, which dump urine into the major and minor calyces
From there, urine is sent to the bladder via the ureter
The urine exits the body via the urethra

13

Cortex

Outer region of the kidney

14

Renal Artery

Brings blood from the kidneys

15

Renal Vein

Brings blood to the kidneys
