Nephritis

Anatomy of the Kidneys

Structure

The kidneys are two bean-shaped organs located on either side of the spine, just below the rib cage?. Each kidney? is about the size of a fist and consists of three main parts:

• Cortex: The outer layer that contains the filtering units called nephrons?.
• Medulla: The inner region with a pyramid-like structure that channels urine into the pelvis?.
• Pelvis: The central area that collects urine before it moves to the bladder?.

Blood Supply

Kidneys receive a rich blood supply through the renal? arteries?, which branch off from the aorta?. Blood enters the kidneys, is filtered through nephrons, and exits via the renal veins?, returning filtered blood to the circulation.

Nerve Supply

The kidneys are innervated by the renal plexus, a network of nerves that helps regulate blood flow, urine production, and other kidney functions.

Nephritis refers to inflammation of the kidneys, which can affect their ability to filter waste and excess fluids from the blood effectively. This condition can lead to various complications, including high blood pressure, kidney damage, and impaired kidney function. Nephritis can be acute? (sudden onset?) or chronic? (long-term).

Types of Nephritis

1. Glomerulonephritis?: Inflammation of the glomeruli?, the tiny filters in the kidneys.
2. Interstitial Nephritis: Inflammation of the kidney’s interstitial tissue, which surrounds the tubules.
3. Pyelonephritis?: A type of urinary tract infection? that has reached the kidneys.
4. Post-Infectious Nephritis: Occurs after infections like strep throat?.
5. IgA Nephropathy (Berger’s Disease): Caused by deposits of the antibody IgA in the kidneys.
6. Lupus? Nephritis: Kidney inflammation caused by systemic lupus erythematosus?.
7. Rapidly Progressive Glomerulonephritis: A swift form of glomerulonephritis that can lead to kidney failure?.
8. Membranous Nephropathy: Involves thickening of the glomerular basement membrane.
9. Focal Segmental Glomerulosclerosis: Scarring in some parts of the glomeruli.
10. Goodpasture Syndrome?: An autoimmune disease? affecting the kidneys and lungs.
