The structure and function of the kidneys (CIE IGCSE Biology SUPPLEMENT)

The engaging PowerPoint and accompanying differentiated worksheets which come as part of this lesson resource have been designed to cover the SUPPLEMENT section of topic 13.1 of the CIE IGCSE Biology specification which states that students should be able to describe the structure and function of the kidneys. Students will initially be introduced to the gross anatomy of the kidneys with the cortex and medulla and the associated ureter before moving on to the fine anatomy of the tubules and focusing on the key functions like ultrafiltration and selective reabsorption. Lots of discussion points and student discovery have been written into the lesson to encourage students to think about why a certain process takes place before attempting to explain it using the Biology. In addition, there are lots of understanding checks and prior knowledge checks so that students are challenged on their knowledge of previously learned topics such as active transport and the components of blood.
The final task of the lesson challenges the students to use their knowledge of the formation of urea from earlier in topic 13 and combine it with what they have learnt in this lesson to arrange statements about the journey of this molecule into the right order

This lesson has been designed for students who are studying the CIE IGCSE Biology course but is suitable for older students who are studying the kidney at A-level and want to recall some of the key details of the structure and function of this organ
