Master Kidney Nephrons: Filtering the Blood fast ⚡ – clear explanations, OCR-aligned.
You’ll cover
• The roles of reabsorption and secretion as filtrate passes through the nephron.
• Movement of glucose, amino acids, ions and water from the filtrate back into the blood.
• Structural adaptations of nephron tubule cells that support efficient reabsorption.
• Differences between the descending and ascending limbs of the loop of Henle.
• How the collecting duct helps produce concentrated urine.
What’s included
• Diagram showing the structure of a nephron and the main transport processes along the tubule.
• Table summarising substances reabsorbed and secreted in different nephron regions.
• Table outlining structural adaptations of proximal convoluted tubule cells for reabsorption.
• Diagram showing epithelial cell structure involved in transport across the nephron tubule.
• Diagram illustrating exchange between nephron tubule cells and surrounding capillaries.
• Diagram showing transport processes in collecting duct epithelial cells.
• Table summarising features of different membrane transport processes.
• Diagram showing water and ion movement in the descending and ascending limbs of the loop of Henle.
