Examples

• The glomerulus is the functional unit of the kidney where filtration begins.
• Damage to the glomeruli can lead to kidney disease and protein loss in urine.
• Each kidney contains approximately one million glomeruli.
• The glomerulus filters small molecules like urea and glucose from the blood.
• Under a microscope, the glomerulus appears as a delicate network of capillaries.
• Inflammation of the glomeruli is called glomerulonephritis.
