|
|
|
lungs
|
remove carbon dioxide from the body
|

|
liver
|
remove nitrogeneous waste/ammonia froom blood and converts it to urea
|
|
|
kidneys
|
remove nitrogrenous waste (urea) and eliminates it from the body (bladder)
|
|
|
ammonia
|
most common nitrogenous waste; converted to liver
|
|
|
cortex
|
outer layer of the kidney; made up of millions of unites called nephrons
|
|
|
medulla
|
inner 2/3 layer of kidney
|
|
|
pelivis
|

|
|
|
nephron

controls the chemical coompostition of the blood and urine.
|
|
|
renal artery
|
where blood enters the liver
|
|
|
renal vein
|

|
|
|
bowmans capsule
|
cup-like structure of the nephron; encloses a bed of capallaries
|
|
|
glomerculus
|
the capalary bed, recieves blood from the renal artery
|
|
|
renal tubule
|
material filtereed from the blood flows through the renal tube
|
|
|
loo of henle
|
lowest area of the renal tubule
|
|
|
filtation
|
materials from the blood are filtered and enter the nephron. Blood in glomerus is under high preasure, which forces urea, glucose, vitamins, and salts through thin capallary walls into bowman's capsule
|
|
|
reabsorptiion
|
the blood reaborbs some of the materials from the nephron tubes. Water, glucose, and minerals are returned to the blood.
|
|
|
secretion
|
other substances pass from the bloo dinto the filtrate. The pH of the blood is adjusted from hydrogen ions entering filtrate.
|
|
|
collecting duct
|
urine is further concentrated be osmosis of water through the wall of the duct into the extra-cellular fluid.
|
|
