Urinary System

Question 1

kidney

Answer 1

-structure where blood is filtered, location where filtered material can be reabsorbed by blood and places where what is not reabsorbed collects as urine

Question 2

Outer layer of kidney

Answer 2

renal cortex

Question 3

middle layer of kidney

Answer 3

renal medulla

Question 4

inner layer of kidney

Answer 4

renal pelvis

Question 5

nephron

Answer 5

microscopic functional units of kidney

- in renal CORTEX and glomerulus surrounding renal medulla

Question 6

glomerular

Answer 6

-CAPILLARY in nephrons which filters
-in renal CORTEX
collected by Bowman’s capsule

Question 7

From Bowman’s capsule, filtrates move to…

Answer 7

convoluted tubules

Question 8

proximal tubules

Answer 8

where glucose and other useful sources are reabsorbed back into blood through walls of surrounding capillaries

Question 9

After proximal tubules…

Answer 9

remain filtrate flows into LOOP OF HENTE, then into DISTAL TUBULE

Question 10

tubular reabsorption

Answer 10

movement of useful material from filtrate back into bloodstream

Question 11

in renal cortex…

Answer 11

distal tubes from numerous NEPHRONS empties into each collecting ducts (filtrate becomes more concentrated as urine)

Question 12

Where does urine empty to

Answer 12

renal pelvis of kidney

Question 13

amount of filtrate collected into Bowman’s capsule is regulated by…

Answer 13

blood pressure

Question 14

What influence kidney on how they regulate how much water is lost from body?

Answer 14

NaCl (Sodium chloride)

Question 15

When bp out of homeostatic range, kidney are employed by…

Answer 15

cardivascular system to return bp to normal

Question 16

renin

Answer 16

enzymes RELEASED by kidney when REDUCED BP detected by baroreceptors in aorta and cartoid aorta

• creates angiotensin 1 from angiotensinogen produced by liver
• liver and kidney produce by enzymes that convert angio 1 to angio 2

Question 17

angiotensin 2

Answer 17

RESTORES blood volume and BP by CONSTRICTING blood vessels, stimulating thirsts, aldosterone, and antidiuretic

Question 18

aldosterone

Answer 18

hormones secreted by adrenal glands which INCREASE reabsorption of sodium; leads to increase reabsorption of chloride ions and water

Question 19

anti-diuretic hormone

Answer 19

-secreted by pituitary gland and increase amount of water able to be reabsorbed from collecting ducts (kidney)

Question 20

antidiuretic and aldosterone hormones…

Answer 20

-increase blood volume while decrease water lost from body in urine

Question 21

diuretic

Answer 21

any substances that cause water to be LOST from body through urination

Question 22

Hormone that causes the Kidneys to return more water to the blood while decreasing volume?

Answer 22

ADH

Question 23

Kidney receives blood by…

Answer 23

renal artery

Question 24

bowman’s capsule

Answer 24

encapsulates the glomerulus

-in renal CORTEX

Question 25

Which two tubules does the renal medulla have?

Answer 25

-proximal and distal convoluted tubules

Question 26

distal tubules

Answer 26

urea and drugs are removed from blood.

-pH in blood is adjusted with H+ ions
