Excretion in Humans | IGCSE and O Level Biology pptx
This detailed presentation on excretion in humans explains how the body efficiently removes waste and maintains homeostasis. It outlines the key roles of the liver, lungs, and kidneys: the liver deaminates amino acids to produce urea; the lungs expel carbon dioxide; and the kidneys filter blood through nephrons—using ultrafiltration and reabsorption—to produce urine while balancing water and salts. With clear diagrams and step-by-step processes, it highlights the structure and function of the glomerulus and tubules, and discusses water balance and osmoregulation.
