Examples of Nephron Disorders and Their Impact on Kidney Function

📚 Quick Study Guide

• 🔬 The nephron is the functional unit of the kidney, responsible for filtering blood and producing urine.
• 💧 Key processes include: filtration, reabsorption, and secretion.
• 🚧 Nephron disorders disrupt these processes, leading to various kidney dysfunctions.
• 📊 Common disorders include: Glomerulonephritis, Nephrotic Syndrome, and Acute Tubular Necrosis.
• 🧬 Glomerulonephritis involves inflammation of the glomeruli, impairing filtration.
• ⚖️ Nephrotic Syndrome is characterized by proteinuria, hypoalbuminemia, edema, and hyperlipidemia.
• ⚠️ Acute Tubular Necrosis (ATN) involves damage to the tubular cells, often caused by ischemia or toxins.
• 🌡️ Diabetes and hypertension are major risk factors for nephron damage.
• 💊 Treatment varies depending on the specific disorder and may include medications, dialysis, or kidney transplantation.
