Task 3 Multicellular organisms and ventilation

This task focuses on taking measurements related to the respiratory system and explaining the need for ventilation systems in multicellular organisms. It covers concepts such as spirometry, vital capacity, tidal volume, residual volume, gaseous exchange, and respiration. The importance of oxygen for organisms and the changes in respiratory systems as organisms get more complex are also discussed. Examples of respiratory and circulatory systems in Amoeba, Locusts, Earthworms, and Mice are explored, along with the explanation of why insects and dinosaurs in the Triassic period could grow so large.
