During major activity, tracheoles adapt by filling with water; anaerobic respiration produces lactate, lowering water potential in muscle cells, causing water to move in by osmosis and allowing oxygen to diffuse in the gas phase for faster delivery.
- ends filled with water - muscles produce soluble lactate by anaerobic respiration - water moves into muscles cells by osmosis down wp gradient - diffusion of oxygen into cells in gas phase - faster diffusion
