Question
Chapter 22, Problem 15CYU
Summary Introduction
To review:
The neural control over respiration.
Introduction:
The neural control of breathing is exerted by the centers located within the brain. A system of nerves and receptors from the brain to the lungs, thoracic cavity, and the arteries controls the movements associated with breathing. Neural control over respiration can be achieved by the influence of various factors.

Which one of the following is a possibility for most
of us in regard to breathing, by making a conscious
effort?
(a) One can breathe out air totally without oxygen.
(b) One can breathe out air through Eustachian
tube by closing both nose and mouth.
(c) One can consciously breathe in and breathe
out by moving the diaphragm alone, without
moving the ribs at all.
(d) The lungs can be made fully empty by forcefully
breathing out all air from them.

Which one of the following is a possibility for most of us in regard to breathing, by making a conscious effort? Justify your option.
a) One can consciously breathe in and breathe out by moving the diaphragm alone, without moving the ribs at all
b)The lungs can be made fully empty by forcefully breathing out all air from them
c)One can breathe out air totally without oxygen
d) One can breathe out air through eustachian tubes by closing both the nose and the mouth
One technique for artificial respiration is mouth-to-mouth resuscitation. The rescuer takes a deep breath, blows air into the patient’smouth, and then lets air flow out. The process is repeated. Explain thefollowing: (1) Why do the patient’s lungs expand? (2) Why does airmove out of the patient’s lungs? (3) What effect do the Po2 and thePco2 of the rescuer’s air have on the victim?

Air moves out of the lungs due to the passive relaxing of the diaphragm and intercostal muscles. Air is forced out of the lungs due to the active contraction of the abdominal and internal intercostal muscles. Air moves out of the lungs due to the passive elastic recoil of the chest wall and lungs.arrow_forwardThere is a bear in the cave, that runs by Xena to get away from the extensive smoke due to Xena cooking on the fire. Xena holds her breath to avoid the bear hearing her breath. Discuss if Xena could die from holding her breath for too long. Make sure that you justify your answer by referring to the physiological control of respiration.arrow_forward
