why is excretion important
Respuesta
  • To provide jobs for toilet manufacturers, toilet paper companies and plumbers
  • To remove poisons from the body
  • To allow metabolic processes to continue without being interfered
  • Maintain salt balance

Respuesta
  • 80% water
  • All glucose (in healthy people)
  • Useful nutrients
  • some mineral salts (to maintain ideal blood concentration

Pregunta 27

Pregunta
What is reabsorbed in the proximal convoluted tubule?
Respuesta
  • 80% water
  • All glucose (in healthy people)
  • Useful nutrients
  • some mineral salts (to maintain ideal blood concentration

Pregunta 28

Pregunta
The distal convoluted tubule regulates salts to allow the blood to be
Respuesta
  • Slightly acidic
  • Perfectly Neutral
  • Slightly basic
  • Very acidic
  • Very Basic

Pregunta 29

Pregunta
ADH
Respuesta
  • means Arteriole-directing hormone
  • means anti-diuretic hormone
  • Secreted by nephrons
  • Regulated by osmo-receptors in hypothalmus
  • More of it in blood causes thrist
  • Controls the permeability of the wall in the DCtubing
  • Little in blood causes little urine to be passed
