!!!KIDNEY FUCNTION IN THE BODY EXPERIMENT!!! (KIDNEY FILTRATION & REABSORPTION) SCIENCE EXPERIMENT

Crazy Chris shows you how you dont have to be a wiz, to understand how kidneys work with this super wicked kool kidney model you can make right at home!

Objection: To understand the importance of the kidneys and how they work by filtration of the blood through reabsorption as well as what the components of urine are.

Materials Needed:
- 2 Half L Water Bottles
- Scissors
- 12 coffee filters
- Clay
- Pen or Pencil
- Ruler
- Large Sheet of Carboard
- Funnel
- Plastic Container
- Fish Tank Tubing
- Tape
- Red Food Coloring
- Water

Step 1) Cut the bottomes off of the half L water bottles. Fill the mouth of the bottle with some clay & poke a pen or pencil through the clay.

Step 2) Cut a 30cm section of the fish tank tubing and insert the fish tank tubing in the clay hole and tighten the clay around the tube both inside & outside the bottle. Test the tube for leaks by pouring water into the container.

Step 3) Put 12-16 of the "THICKEST" coffee filters you can fine, into each kidney model.

Step 4) Attach the kidney models & the funnel using tape to the carboad and place the tubes into the funnel. Place a plastic container below the funnel

Step 5) Drip "1 DROP" of food coloring into some water, mix this and pour a small amount of the water into the kidney model. "DO NOT" pour the entire container of water into the kidney model, only pour small amounts each time.

HOW DOES IT WORK:
The water flows through the coffee filters but the food coloring gets absorbed by the coffee filters which is why the water comes out clear & not red similar to how your kidneys filter your blood stream. Blood is broughto to the kidneys via the renal artiers. Once inside the kidneys the blood passes through a million tiny filters known as nephrons. The blood is under so much pressure that most of the plasma leaks out of the blood stream leaving mostly just the blood cells. Your kidney then go through a re-absorbtion process which allows only the plasma to be returned to the blood stream. Dangerous chemicals, uneeded chemicals and excess water are sent down the ureters to be stored in the bladder. The feeling you need to drain your bladder comes from the pressure of surounding organs as the bladder fills up.

  • @Socoolscienceshow can you give me your full name i need to list your name on my science exit project on my bibliography

  • @MrNeimaGerami you wont need my full name for your bibliography heres how to site a website in your bibliography;

    company; socoolscienceshow - "KIDNEY FUNCTION IN THE BODY EXPERIMENT (Kidney Filtration & Reasbosption) Science Experiment. - URL (wich I cant post in the comment section but just copy exactly the URL in your address bar) - 2/24/12 <--- (or what ever the date is you were collecting all this infomration from the website.)

  • yo thanks so much i had a exit project and i used your model and i did good on my project thank you so much ill subscribe

  • @sonic2fan98 your welcome and thanks for the subscription its means alot not just to me but the awesome youtubers who want to continue watching sci files each week and grow the socoolscienceshow channel :D

  • @TheNightcharge Thanks very much :D

  • This is a cool video. P.S. You're funny! :D

  • Thanks for this. very helpful. I was trying to do this and demonstrate but did not see the food coloring getting filtered. The output was still red. Something I am missing or can do to filter it better. Was it any specific type of food color? I bought red food color from the McCormick. Appreciate a quick response.

  • Thanks alot!!! :D
