Glomerulus Infection

Pathophysiology of Glomerulus Infection

Structure of the Glomerulus

• Glomerulus: A ball-like cluster of capillaries? (tiny blood vessels) inside the kidney?’s filtering units called nephrons?.
• Bowman’s Capsule: Surrounds the glomerulus and collects the filtered fluid.

Blood Supply

• Afferent Arteriole: Brings blood into the glomerulus.
• Efferent Arteriole: Carries blood away from the glomerulus.

Nerve Supply

• The kidneys have a complex nerve supply that helps regulate blood flow and filtration rates in the glomeruli.

Types of Glomerulus Infections

1. Acute? Glomerulonephritis: Sudden onset?, often following an infection like strep throat?.
2. Chronic? Glomerulonephritis: Gradual loss of kidney function over time.
3. IgA Nephropathy: Caused by deposits of the protein IgA in the glomeruli.
4. Post-Infectious Glomerulonephritis: Follows infections such as skin or throat infections.
