Study Notes
Nephron Structure and Function
- Blood passes through three layers in the nephron: renal corpuscle, proximal convoluted tubule, and distal convoluted tubule for filtration.
- The fluid that exits at the end of the tubule is called urine, which is a concentrated waste product.
Nephron as Functional Unit
- The structural and functional unit of the kidney is the nephron.
Water Reabsorption and Substances Exchange
- Water is reabsorbed and substances are exchanged in the renal tubules of the nephron.
Number of Nephrons
- A healthy adult has around 1 million nephrons in each kidney, responsible for filtering waste and excess substances from the blood.
Test your knowledge about the structure and function of nephrons, the microscopic units of the kidney responsible for filtering blood and producing urine.
