Excretion in Humans | O Level , IGCSE Biology pptx
This IGCSE Biology presentation on excretion in humans provides a thorough overview of how our bodies eliminate metabolic waste and regulate internal balance. It details the liver′s role in converting excess amino acids into urea via deamination, and explains how the kidneys filter blood through millions of nephrons. The process of urine formation—from ultrafiltration in the glomerulus to reabsorption in the renal tubules and final collection in the bladder—is clearly illustrated. Additionally, the presentation highlights how other organs, like the lungs and skin, assist in waste removal. Topics such as kidney disease, dialysis, and transplantation are also discussed.
