One early morning, a lady came into room 17. Her name is Tracy, and also room 16 came. Tracy was from the hospital, so we were excited about what she was going to be talking to us about.
Tracy was telling the students all about kidneys. Tracy said that kidneys clean your blood, just like a washing machine. Every one minute, the blood goes through your kidneys. Tracy showed the students some photos on her slide show. The students saw a lady in hospital with tubes going through her arm. That machine is called a Dialysis. The Dialysis is a machine that keeps your kidneys going. Some people have to stay on a Dialysis for 5 hours, three times a day.
Next Tracy told the students that some people are mostly born with two kidneys, but some only have one. Some people donate kidneys to the people who have kidneys that are not working, so some people will have three and leave the bad one in their body.
Last but not least, Tracy showed us a lamb kidney and an ox kidney. The students were amazed of how big the ox kidney compared to the lambs. Then she showed us how much sugar is in healthy fruit drinks.
