Urinary System Chapter 26

Front 1

most physiological wastes are removed by

Back 1

the urinary system

Front 2

three major functions of the urinary system

Back 2

1. excretion
2. elimination
3. homeostatic regulation of the volume & solute concentration of blood plasma

Front 3

the removal of organic waste products from body fluids

Back 3

excretion

Front 4

the discharge of waste products into the environment

Back 4

elimination

Front 5

performs the excretory functions of the urinary system

Back 5

kidneys

Front 6

organs that produce urine

Back 6

kidneys

Front 7

fluid containing water, ions, and small soluble compounds

Back 7

urine

Front 8

urine leaving the kidneys flows along...

Back 8

the urinary tract

Front 9

the urinary tract consists of:

Back 9

ureters

Front 10

paired tubes of the urinary tract

Back 10

ureters

Front 11

transports urine toward the urinary bladder

Back 11

ureter

Front 12

temporarily stores urine prior to elimination

Back 12

bladder

Front 13

conducts urine to exterior (and in males, transports semen as well)

Back 13

urethra

Front 14

responsible for the elimination of urine

Back 14

bladder and urethra

Front 15

process of elimination of urine

Back 15

urination/micturition

Front 16

covers the outer surface of the kidney & lines the renal sinus

Back 16

fibrous capsule

Front 17

an internal cavity within the kidney

Back 17

renal sinus

Front 18

the kidney has an outer ____ & and inner ______

Back 18

-outer cortex
-inner medulla

Front 19

superficial portion of the kidney that is in contact with the fibrous capsule

Back 19

renal cortex

Front 20

consists of 6-18 renal pyramids

Back 20

renal medulla

Front 21

conical or triangular structures that make up the renal medulla

Back 21

renal pyramids

Front 22

the tip of each renal pyramid that projects into the renal sinus

Back 22

renal papilla

Front 23

band of cortical tissue that separates each renal pyramid and extends into the medulla.

Back 23

renal columns

Front 24

consists of a renal pyramid, the overlying area of renal cortex, and adjacent tissues of the renal columns

Back 24

renal lobe

Front 25

urine production occurs in the:

Back 25

renal lobes

Front 26

ducts within each renal papilla discharge urine into the cup-shaped drain called a:

Back 26

minor calyx

Front 27

four or five minor calyces merge into a :

Back 27

major calyx

Front 28

two or three major calyces form the:

Back 28

renal pelvis

Front 29

large funnel shaped chamber that fills most of the renal sinus and is connected to the ureter, which drains the kidney

Back 29

renal pelvis

Front 30

urine production begins in microscopic, tubular structures

Back 30

nephrons

Front 31

nephrons are located...

Back 31

in the cortex of each renal lobe

Front 32

each kidney receives blood through a:

Back 32

renal artery

Front 33

the renal artery enters through the ___ and provides blood to ___

Back 33

-renal sinus
-segmental arteries

Front 34

segmental arteries further divide into:

Back 34

interlobar arteries

Front 35

radiate outward through renal columns between the renal pyramids

Back 35

interlobar arteries
