    In this video, we look at the kidneys. I start by discussing the three ways that water can leave the body. We then look at how the kidneys adjust the levels of molecules in the blood and then we finish by looking at how urea is made (for higher tier students).

    idk if this is helpful to anyone but how i literally pass my tests is watch the videos necessary to my topic and after each vid i grab a piece of paper and write down everything i remember i then rewatch it and add any bits i missed once i've watched a few vids i revisit earlier ones and write down what i remember again to keep it clear in my mind. to summarise, watch the video at least twice and write down what you remember after you watch it once and later on when you've done some other stuff. hope this helps someone x

    • @Freesciencelessons

      It's from a region of high WATER concentration (ie a dilute solution) to a region of low water concentration (ie a concentrated solution).

      Hi I'm not the teacher and am in year 9 but I think I can help. Water is a waste product of respiration so respiration creates water, if you have too much water the kidneys remove the excess water like in the video. Sorry I'm not as smart as Sir.
