Glomerulopathy

Glomerulopathy refers to any disease that affects the glomeruli, the tiny filters in your kidneys. These filters help clean your blood by removing waste and extra fluids, which eventually become urine. When these filters are damaged, it can lead to serious health problems.

Pathophysiology

Structure

• Glomeruli: Small structures in the kidney where blood filtration happens.
• Kidneys: Two bean-shaped organs that filter waste from the blood.

Blood Supply

• The glomeruli receive blood from the renal artery, which branches into smaller arteries and capillaries.

Nerve Supply

• The kidneys are supplied by nerves from the autonomic nervous system, which helps regulate blood flow and kidney function.
