Kidneys/Urinary System 12/13/20

This week we finished doing the urinary system. I wasn’t at school last Monday, so I missed a bit.

Lots of things are in the blood, and not all good things. Cells die and are in the blood, and other gross things that are considered waste are in the blood, too. So, the kidneys come into play. When the blood is brought into the kidneys by the renal artery, it gets filtered by the nephrons which are in the kidneys. They take out all the bad and gross things – this is called urine. The renal vein then takes the healthy things and returns them to the body. Excess water and waste is urine. They kidneys recycle the good things back into the blood, including vitamins, amino acids, glucose, etc.

Questions:

Why is there more than one language in the world?

Do chipmunks give other chipmunks hugs?

Why are oranges called oranges?
