Post-infectious Glomerulonephritis

Pathophysiology (Structure, Blood, Nerve Supply)

Structure

• Glomeruli: These are tiny structures in the kidneys responsible for filtering blood. Each kidney? contains about a million glomeruli.
• Nephrons?: The glomeruli are part of nephrons, the basic functional units of the kidney, which help in urine formation.

Blood Supply

• The kidneys receive blood from the renal? arteries?, which branch off from the abdominal aorta?.
• Blood flows through the glomeruli, where filtration occurs. The filtered blood then continues through the renal tubules, where further processing occurs.

Nerve Supply

• The kidneys are innervated by the autonomic nervous system, which regulates their functions. This nerve supply helps control blood flow and the filtration process.

Types of Post-infectious Glomerulonephritis

1. Acute? Post-infectious Glomerulonephritis: This is the most common type, often occurring after a bacterial infection?.
2. Chronic? Post-infectious Glomerulonephritis: This is less common and may develop slowly over time, possibly leading to long-term kidney damage.
