1. Environmental factors that control the breathing rate can be temperature, altitude, humidity,
moisture, and air pressure. Each of this can result in the breathing rate to increase or decrease, for
example in cold weather your breathing rate increases to help pump oxygenated blood to travel
around your body to become warm.
2. The respiratory and circulatory are related in many ways but the most important is its connection
to the lungs. As the circulatory uses oxygen to pump blood around the blood it is received from
the respiratory system that gets oxygen from the air to your body. Not only this, but also getting
rid of carbon dioxide in your body is a process both work together in.
3. The main factor that can affect heart diseases is obesity, which can easily be prevented by
eliminating smoking, poor dieting, and inactivity.
4. My hypothesis which was, I think breathing rate stops immediately after hyperventilation was
correct because in our experiment we were able to experience apnea, which is the stoppage of
breath after hyperventilation. Since the concentration levels of carbon dioxide are decreased after
hyperventilation you have no levels of carbon dioxide in your body which is what divers usually
do to help keep their breathe in longer without having to exhale.
