excretion Flashcards
(32 cards)
nephron processes
ultrafiltration in bowman’s capsule
selective reabsorption in proximal convoluted tubule
water reabsorption in loop of henle.
orithine cycle
Deamination of excess amino acids -> NH3 + CO2 + orothine->an H2O is removed -> citruline ->(NH3 added and a H2O is removed) -> arginine -> (H2O is added and urea is removed) -> orithine
hormone tested for in pregnancy tests
human chorionic ganadotrophin
what shows a positive test line on pregnancy tests
hCG- antibody- enzyme complex
Anabolic testing positive result
higher testosterone to epitestosterone levels
urine samples can be used to test for
- drugs
- alcohol
excess fluid
hypervolemia
excess potassium
hyperkalemia
excess phosphate
hyperphosphatemia
calcium deficiency
hypocalcemia
what can be caused by kidney failure
electrolyte imbalance
hypervolemia etc
hepatic portal vein
carries blood from digestive system to liver
liver cells
hepatocytes
where does glycogenolysis and glycogenisis occur
hepatocytes
amino acids deaminated to …
- ammonia
- keytones
detoxification in the liver
chemicals oxidised or reduced by enzymes
hepatic artery
provides oxygenated vlood to liver
hepatic vein
blood exits liver and flows back to the heart
Bile contains
- bile salts for digestion
- bile pigments for breakdown of haemoglobin
liver cells are arranged in
lobules, with each lobule dupplied by hepatic artery and hepatic portal vein
blood vessels that surround lobules…
sinusoids
….. surounds renal medulla
renal cortex
nephrons extend
from cortex into medulla
