Today - Basic 3.4 - Excretion 
Goal:
You can name the parts of the kidneys and urinary tracts with their features and functions.

Practice: 
Ex. 1-8



Slide 10 - Diapositive

Execretory organs
Excretion = to get excess, unnecessary, and toxic substances from your blood and remove it from your body

Execretory organs = lungs, liver, kidneys, skin

Slide 11 - Diapositive

Slide 12 - Diapositive

Components of a kidney
Renal cortex
Renal medulla
Renal pelvis

Slide 13 - Diapositive

Renal cortex & Renal medulla
Remove from the blood:
  • Waste products
  • Excess water
  • Excess salt
  • All harmful substances

  • Combined we call this:  urine

Slide 14 - Diapositive

Renal pelvis
Collects the urine

Collected urine is transported to the bladder through the ureters.

Slide 15 - Diapositive

kidneys
excrete water, minerals and other waste products



Slide 16 - Diapositive

Kidneys
  • Two kidneys
  • Receive blood from renal artery
  • Blood plasma is filtered from waste products and excess substances.
  • Result is urine.`
  • Molecules that the body doesn't need are removed --> excretion.
  • The kidneys filter ~  180 liter a day

 Kidney
- Blood enters via Renal Artery
- Flows to the Cortex
- Is cleaned in Nephrons in the
