OK – this is the next-to-last section of the syllabus before we begin our options.  Here are some of the key points we’ll learn:

  • What is excretion? (And what isn’t)
  • How to draw and label a diagram of the kidney.
  • What a nephron is, how to annotate a diagram of one to help explain the processes of ultrafiltration and reabsorption.
  • What is osmoregulation, and what role do hormones play in it?
  • What are the differences between concentrations of various components in blood and urine, and the reasons for those differences.

We’ll again use this wonderful presentation from Mr S Taylor as well as our textbooks.  In addition, once we’ve completed this topic, you could watch this video.  It’s a little complicated, so I wouldn’t recommend watching it at the start, but after we’ve covered some of the theory.

Another useful review powerpoint from Mr Hobbins: 11.3 The Kidney

Enjoy!
