excretory system

Question 1

what does the kidney do

Answer 1

its job it to filter blood from urine

Question 2

what are ureters job

Answer 2

tube on kidney that leads to bladder (acts as transport)

Question 3

urinary bladder job

Answer 3

stores all the urine

Question 4

what does the uretha do

Answer 4

its the pee tube from bladder to outside body (exsit passage)

Question 5

were does the renal artery bring blood to and from

Answer 5

brings blood to kidney

Question 6

were does the renal vein bring blood to and from

Answer 6

it brings blood away from the kidney

Question 7

renal cortex location

Answer 7

outside of kidney

(you can remember this is the outside by corTEX and tex is like texas and they wear hats and there on the outside of the head)

Question 8

renal medulla location

Answer 8

middle area of kidney
(can remember by m=middle)

Question 9

renal pelvis location / function

Answer 9

lts a branch like thing thats thick and it stores urine and is storage unit

Question 10

3 main things kidneys do

Answer 10

-rehabsorb essential things
- filter blood
- secreate waste (pee) with things we dont need

Question 11

how do kidneys do their 3 main functions

Answer 11

-remove wastes from blood (mictritation)
- balances blood ph by removing hydrogen ions
- maintains water balance (from adh)

Question 12

what is one of the main nutrients we need and what is the excess broken down into

Answer 12

protein and the excess is broken down into carbs and nitrogenous waste that are toxic

Question 13

how does the kidney maintain good ph

Answer 13

by secreating (peeing out) hydo ions and ammonia and reabsorption of bicarbonate

Question 14

how does kidney maintain water balance

Answer 14

by hormoes (adh) and (aldosterone)

by active and passive transport that will help water diffuse back into body

Question 15

what does adh do and how does it work

Answer 15

secreated by pituitary and it pulls more water back into kidney for when its dehydrated

Question 16

what does aldosterone do and how doe sit work

Answer 16

released by adrenal gland (edge kidney) and it responds to low bp and rehabsorbs sodium and water follows it

Question 17

what does the afferent arteriole do

Answer 17

blood that enters bowmans capsule

Question 18

what does efferent arteriole do

Answer 18

blood that leaves bowmans capsule

Question 19

what does the glomerulus do

Answer 19

its the filtrator and is the spegetti of capillarys in bowmans capsule

Question 20

where is the proximal tubule

Answer 20

closest to bowmans caspsule

Question 21

what doe sthe bowmans capsule do

Answer 21

filtrates by squeezing

Question 22

where is the loop of henle

Answer 22

its the dip down into the kidney

Question 23

where is the distal tube

Answer 23

its the farthest away from the bowmans capsule

Question 24

where are the collecting ducts

Answer 24

they do fine tuning to the pee and maintain it

Question 25

how does filtration work

Answer 25

High blood pressure in the glomerulus forces materials from an area of high concentration to low concentration

(passive transport)

Question 26

what stays it in capillaries

Answer 26

red blood cells, plasma proteins, platelets
to big so it stays

Question 27

what is reabsorbed in body proximal tubule

Answer 27

water, bicarbonate, sodium, nutrients, potassium

Question 28

what is reaborbed in the loop of Henle

Answer 28

water (descending), salt (ascending)

Question 29

what is reaborbed in distal tubule

Answer 29

salt, water, bicarbonate

Question 30

what is reabsorbed in the collecting Duct

Answer 30

salt, urea and water

Question 31

secreation (removed from body) proximal tubule

Answer 31

hydrogen ions and Ammonia

Question 32

secreation (removed from body) distal tubule

Answer 32

potassium and hydrogen ions
