Urinary System

• Deamination:

  • the removal the amino group from an amino acid molecule
• Deamination equasion:

  amino acid + oxygen -(enzymes)-> carbohydrate + amonia

  then: energy + CO2 + amonia --> Urea + water
• Deamination proccess:
• Excretion:

  • removal of the wastes of metabolism from the body
• kidneys:

  • princple excretory organs of human body filter from blood and regulate the balance of water and salts in the blood plasma
• Excretory organs:

• Collecting duct:

  • tube in kidney that collects filtrate from several nephrons
• Creatinine:

  • waste products from breakdown of muscles
• Efferent arteriole:

  • blood vessle that leaves organ
• Facilative reabsorbtion:

  • proccess whereby carrier proteins assist movement of substances through the cell membrane
• Filtrate:

  • fluid remaining after filtration has taken place
• Glomurular capsuel:

  • collects filtered water and other substances from blood
• Glomurular filtration:

  • filtration of blood in kidney
• Loop of Henle:

  • plays major role in reabsorbtion of water and salts from the filtrate
