Anatomy & Physiology Ch. 24 Urinary System

Front 1

Term for voiding (urinating)

Back 1

Micturation

Front 2

Organs of the urinary system

Back 2

Kidneys, ureters, urinary bladder, & urethra

Front 3

The 3 major regions of the kidney

Back 3

Cortex, medulla, & pelvis

Front 4

The 5 functions of the kidneys

Back 4

1. Excrete waste

2. Regulate blood volume

3. Regulate electrolytes

4. Regulate pH & BP

5. Stimulate red blood cell production

Front 5

The renal cortex descends between the pyramids as the

Back 5

Renal columns

Front 6

Surrounds the kidneys

Back 6

Renal capsule

Front 7

The calyces receive urine from the

Back 7

Collecting ducts

Front 8

Main function of urinary bladder

Back 8

Storage

Front 9

The detrusor muscle is concerned with

Back 9

Micturation

Front 10

The trigone, detrusor muscle, and internal sphincter are all located here

Back 10

Urinary bladder

Front 11

Blood vessels that are primarily concerned with reabsorption

Back 11

Peritubular capillaries

Front 12

Peritubular capillaries are an extension of

Back 12

Efferent arterioles

Front 13

An increase in GFR results in an increase in

Back 13

Urine formation

Front 14

Substance that is filtered by the glomerulus & excreted in urine

Back 14

Creatinine

Front 15

The juxtagolomerular apparatus (JGA) secretes

Back 15

Renin

Front 16

The distal convoluted tubule reabsorbs Na+ & water in response to

Back 16

Aldosterone

Front 17

ADH stimulates the collecting duct to do this

Back 17

Reabsorb water

Front 18

Natriuresis refers to renal excretion of

Back 18

Na+ (sodium)

Front 19

Excretion of Na+ is generally accompanied by excretion of

Back 19

Water

Front 20

ADH is secreted by this gland

Back 20

Posterior pituitary gland

Front 21

ADH is secreted in response to these 2 things

Back 21

Low blood volume & dehydration

Front 22

ADH causes renal secretion of these 3 things

Back 22

Sodium, potassium, & water

Front 23

Angiotensin II is a potent

Back 23

Vasoconstrictor

Front 24

A drug that blocks the effects of aldosterone decreases this

Back 24

Reabsorption of Na+ & water

Front 25

Hormone that increases vascular resistance (BP) and causes release of aldosterone

Back 25

Angiotensin II

Front 26

Prolonged hypotension can cause

Back 26

Oliguria

Front 27

Composition of urine includes

Back 27

Amount, pH, specific gravity, color, & abnormal constituents

Front 28

Creatinine is present in urine

Back 28

In normal conditions

Front 29

An elevated creatinine level in blood most likely indicates

Back 29

Declining renal function (renal failure)

Front 30

Regarding pH, UTIs are more common in alkaline urine than

Back 30

Acidic urine

Front 31

Normally, urine contains trace amounts of this simple sugar

Back 31

Glucose

Front 32

Normal urine does not contain significant amounts of this protein

Back 32

Albumin

Front 33

Handled by the kidneys as either urea or ammonia

Back 33

Nitrogen

Front 34

Albuminuria & generalized edema are usually accompanied by

Back 34

Hypoalbuminemia

Front 35

How is urea transported?

Back 35

From the liver to kidneys by the blood

Front 36

Organ where urea is made

Back 36

Liver

Front 37

Urea is excreted by the

Back 37

Kidneys

Front 38

Pyuria (puss in urine) is indicative of

Back 38

Infection

Front 39

A sudden decline in blood pressure to 80/45 is most apt to cause

Back 39

Oliguria

Front 40

This class of drugs works by blocking the tubular reabsorption of Na+

Diuretics
