**Knowledge of other parts of the urinary system, the structure of the kidney, and the structure of a nephron is not required.**
AQA spec link: 5.3.3
Relevant chapter: B12-Homeostasis in action. ( Note: This topic is for BIOLOGY only not for combined science students). AQA Biology third edition textbook-Page 185-186
*The new specification requires students to know the following;
Students should be able to describe the function of kidneys in maintaining the water balance of the body. The kidneys produce urine by filtration of the blood and selective reabsorption of useful substances such as glucose, some ions, And water.
Knowledge of other parts of the urinary system, the structure of the kidney, and the structure of a nephron is not required.
Students should be able to translate tables and bar charts of glucose, ions, and urea before and after filtration. Students should be able to describe the effect of ADH on the permeability of the kidney tubules.
The water level in the body is controlled by the hormone ADH which acts on the kidney tubules. ADH is released by the pituitary gland when the blood is too concentrated and it causes more water to be reabsorbed back into the blood from the kidney tubules. This is controlled by negative feedback.

A great resource with good activities for the students. Thank you for sharing.
Decent material, well laid out and enough here to be able cover the spec. Would have appreciated a mark scheme for the exam question - if that was included 5/5.
Great PowerPoint with lots of activities and video links :)
