Definition

Nephritis is a medical condition that affects the kidneys, which are vital organs responsible for filtering waste from the blood. This guide provides an in-depth look at nephritis, covering its anatomy, types, causes, symptoms, diagnostic methods, treatments, and more. Written in simple language, this article aims to enhance your understanding and awareness of nephritis.

Nephritis is an infection, or irritation, often causing pain, swelling, heat, or redness. সহজ বাংলা: শরীরের প্রদাহ; ব্যথা, ফোলা বা লালভাব হতে পারে।" data-rx-term="inflammation" data-rx-definition="Inflammation is the body’s response to injury, infection, or irritation, often causing pain, swelling, heat, or redness. সহজ বাংলা: শরীরের প্রদাহ; ব্যথা, ফোলা বা লালভাব হতে পারে।">inflammation of the kidneys. The kidneys play a crucial role in filtering waste and excess fluids from the blood, which are then excreted as urine. When the kidneys become inflamed, their ability to function properly is compromised, leading to various health issues. Nephritis can affect different parts of the kidneys and may be acute (sudden onset) or chronic (long-lasting).

Anatomy of the Kidneys

Understanding the structure and function of the kidneys helps in comprehending how nephritis affects them.

Structure

  • Location: The kidneys are located on either side of the spine, just below the rib cage.

  • Parts of the Kidney:
    • Cortex: The outer layer where blood filtration begins.
    • Medulla: The inner region that contains structures called pyramids.
    • Nephrons: Tiny filtering units within the kidneys that remove waste from the blood.

Blood Supply

  • Renal Arteries: Bring blood rich in waste to the kidneys for filtration.
  • Renal Veins: Carry the filtered blood away from the kidneys.
  • Importance: Adequate blood flow is essential for the kidneys to function correctly.

Nerve Supply
