how much fluid can your lungs hold
Best Answer: A pair of human lungs can fill upto 6lts of water or air. It depends how fit you are. If you're fit then you can fit up to 6 litres of air, if you smoke and the surface area of the alveoli is smaller or you're not healthy in general, then you can have like 3 litres of space in your lungs, or even less.
