Hello students, in this video we will discuss about respiration.
00:04
First, hyperventilation affect body's ability to hold breath by reducing the level of carbon dioxide in the body.
00:25
When we hyperventilate, we breathe at an increased rate and depth which lead to excessive elimination of co2.
00:43
Exercise increases breathing rate.
00:47
During physical activity, muscles require more oxygen to meet the increased energy demands.
00:55
To supply this oxygen, body increases the rate and depth of breathing to facilitate gas exchange in the lungs.
01:11
Next, hyperventilation is likely to shorten the length of time one can hold breath.
01:38
Hyperventilation lowers the level of carbon dioxide in the blood by breathing rapidly and deeply.
01:48
Excess co2 is expelled from the lungs reducing its concentration in the blood stream.
02:07
Whereas, exercise may initially increase the level of co2 in the blood due to increased production from the working muscles.
02:29
However, the increased breathing rate during exercise help to remove the excess co2 gradually bringing its level back to normal.

Hyperventilation causes phenol red to become colorless to yellow more quickly...
