Understanding the Structure of the Kidney
The kidney is a vital organ responsible for filtering blood, removing waste, and regulating fluid balance. Its functional unit is the nephron, which is highly coiled and complex.
What is a Nephron?
- The nephron is the basic structural and functional unit of the kidney.
- Each kidney contains approximately one million nephrons.
- Nephrons play a crucial role in urine formation and maintaining homeostasis.
Components of a Nephron
- Bowman's Capsule: A cup-like structure that encloses the glomerulus (a network of tiny blood vessels).
- Glomerulus: Filters blood, allowing water, salts, and small molecules to pass while retaining larger molecules like proteins and blood cells.
- Renal Tubule: Highly coiled and consists of:
- Proximal Convoluted Tubule: Reabsorbs essential nutrients and water.
- Loop of Henle: Establishes a concentration gradient that aids in water reabsorption.
- Distal Convoluted Tubule: Further adjusts the composition of urine by reabsorbing additional substances.
Functions of Nephrons
- Filtration: Removing waste products from the blood.
- Reabsorption: Retrieving necessary substances back into the bloodstream.
- Secretion: Eliminating excess ions and waste from the blood into the urine.
Conclusion
The nephron's highly coiled structure enhances its ability to efficiently filter blood and produce urine. This intricate design is essential for maintaining the body's overall health and fluid balance, making option 'B' the correct answer.
