The processes of filtration and selective reabsorption within the kidney tubules (nephrons). 5. How water levels are controlled by Anti-Diuretic Hormone (ADH). The role of the hypothalamus and pituitary gland. The effect of ADH on water reabsorption in the kidney tubules. 6. The concept of negative feedback in regulating blood water concentration. ** CHAPTERS ** 0:00 Introduction to Kidney Functions 0:24 Filtering Blood & Removing Waste (Urea) 0:50 Regulating Ions and Water 2:50 How Kidneys Work: Filtration & Selective Reabsorption 4:23 How Water Levels Are Regulated (ADH) 6:13 Negative Feedback Loop ** PLAYLISTS **    • GCSE Maths (9-1)      • GCSE Biology (9-1)      • GCSE Chemistry (9-1)      • GCSE Physics (9-1)      • A-Level Biology   #GCSE #Biology #study
