Excretory System includes these organs |
lungs, skin, kidney |
|
|
Main organ of excretory system |
kidneys |
|
|
Function of the kidney |
blood filtration |
|
|
Main filtration unit of kidney |
nephron |
|
|
Three steps to blood filtration |
filtration, reabsorption, excretion |
|
|
Where filtration occurs |
glomerulus, Bowman's capsule |
|
|
Where reabsorption occurs |
loop of Henle |
|
|
Where excretion occurs |
collecting ducts that lead to ureters that lead to bladder then exit through urethra |
|
|
Path of blood through kidney |
Rental artery --> glomerulus (all filtrate leaves) --> capillaries (nutrients/water reabsorbed)--> rental vein |
|
|
Path of filtrate through kidney |
Rental artery --> glomerulus --> Bowman's capsule --> Loop of Henle --> Collecting duct if waste, back to blood if reabsorbed |
|
|
Active transport in the excretory system |
Active transport during reabsorption of materials back into the blood |
|
|
Passive transport in the excretory system |
diffusion of materials across the space between the glomerulus and the Bowman's capsule Osmosis of water during reabsorption |
|
Brown structures |
kidneys |
|
Red vessel entering kidney |
renal artery |
|
Blue vessel exiting kidney |
renal vein |
|
Structure that leads from kidney to bladder |
ureter |
|
Structure that holds urine |
bladder (urinary blader) |
|
Structure that carries urine from bladder outside the body |
urethra |
|
Structure |
nephron |
