lan's Answer::It was real easy to breathe while sitting, because it was relaxing. But when walking, It got a little harder. It was kinda like trying to breathe in and out of your nose with a stuffy nose, and running got really hard, it was like trying to breathe with your mouth, while it was 3/4 shut.
QUESTION 2:Why do you think that breathing through the wide straw caused the effects that you described?
lan's Answer:: Since the straw is thinner than your mouth, I think that the straw limits you to only a certain amount of air.
QUESTION 3:Did breathing through the thin straw affect you differently than breathing through the wide straw? If so, explain why you think this occured.
lan's Answer:: Yes, because the thin straw is thinner(Heh, Heh)than the wide straw so even breathing was hard. I had to gasp for air a few time and, or cheat (Breathing through nose). Also, the circumference is way different and smaller than wide straw.
QUESTION 5 (QUESTION 4 not required):How does your breathing change as you become more active? Why do these changes happen?
lan's Answer:: When exercising, most of the muscles in our body speed up their metabolism. As they run out of energy, the body needs to produce more energy. More oxygen is required to produce the energy needed to keep exercising and other processes.In a way, the increased need for energy causes our body to "starve" for oxygen. The instinctive response we have to compensate for this sudden need of oxygen is breathing faster.
