How do nephrons filter blood?

Nephrons filter blood through the glomerulus, where small molecules like water, salts, urea, and glucose pass into the Bowman’s capsule. This filtrate is then processed in the tubules, where essential substances are reabsorbed, and waste products are concentrated into urine.

How is urea formed in the human body?

Urea is formed in the liver through the urea cycle when excess amino acids are broken down. The nitrogen from amino acids is converted into ammonia, which is toxic. The liver converts ammonia into urea, which is less toxic and can be safely excreted by the kidneys.
