Excretion in Humans | O Level Biology pptx
This IGCSE Biology presentation on excretion in humans provides an in-depth look at how the body eliminates toxic metabolic waste while maintaining fluid balance and homeostasis. It explains the roles of key organs—the kidneys filter urea, water, and salts from the blood through nephrons, while the liver converts excess amino acids into urea via deamination. The presentation also outlines the structures and processes involved in urine formation, including ultrafiltration in the glomerulus, reabsorption in the renal tubules, and the transport of urine through the ureters, bladder, and urethra.
