Question
Chapter 10, Problem 2CT
Summary Introduction
To explain: The way in which hyperventilation affects the nervous controls over breathing.
Introduction: Hyperventilation is the condition appears due to over breathing. Hyperventilation leads to decrease in carbon dioxide and increase in pH. Hyperventilation may lead to respiratory alkalosis or hypocapnia.

A spinal cord injury at C2 results not only in paralysis but also in a lifetime on a respirator. Why does an injury this high affect ability to breathe?
Although respiratory muscles are voluntary, you cannot hold your breath until you lose consciousness because your brain will force you to ventilate (= breathe) before then. Explain how the brain ‘knows’ when to stimulate ventilation.
please help with examples
Daniel, the swimmer with the fastest time on the college swim team, routinely hyperventilates before a meet, as he says "to sock some more oxygen into my lungs so I can swim longer without having to breathe." "Furthermore, my heart won't have to adjust it's output".
First of all, what basic fact about oxygen loading has Daniel forgotten (a lapse leading to false thinking)? Do you think that hyperventilation will provide him with enough oxygen to increase his endurance during the race?
