The pontine respiratory group is responsible for all of the following functions EXCEPT __________.

Textbook Question

Has a video solution.

Textbook Question

In mouth-to-mouth artificial respiration, the rescuer blows air from his or her own respiratory system into that of the victim. Which of the following statements are correct? (1) Expansion of the victim's lungs is brought about by blowing air in at higher than atmospheric pressure (positive-pressure breathing). (2) During inflation of the lungs, the intrapleural pressure increases. (3) This technique will not work if the victim has a hole in the chest wall, even if the lungs are intact. (4) Expiration during this procedure depends on the elasticity of the alveolar and thoracic walls. a. all of these, b. 1, 2, 4, c. 1, 2, 3, d. 1, 4.

Has a video solution.

Textbook Question

A baby holding its breath will a. have brain cells damaged because of low blood oxygen levels, b. automatically start to breathe again when the carbon dioxide levels in the blood reach a high enough value, c. suffer heart damage because of increased pressure in the carotid sinus and aortic arch areas, d. be called a 'blue baby.'

Has a video solution.

Textbook Question

Damage to which of the following would most likely result in cessation of breathing? a. the pontine respiratory group, b. the ventral respiratory group of the medulla, c. the stretch receptors in the lungs, d. the dorsal respiratory group of the medulla.

Has a video solution.

Textbook Question

Name two chemical factors that modify respiratory rate and depth. Which is usually more important?

Has a video solution.

Textbook Question

Define hyperventilation. If you hyperventilate, do you retain or expel more carbon dioxide? What effect does hyperventilation have on blood pH? On breathing rate?

Has a video solution.

Textbook Question

After a week of scuba diving in the Bahamas, Mary Ann boards an airplane. During her flight home, she develops aching joints, nausea, and dyspnea, which resolve upon landing. During the flight, the cabin pressure was equivalent to an altitude of 8000 feet. Explain her problems.

Has a video solution.

Textbook Question

Prolonged vomiting can result in significant loss of hydrogen ions from the blood, and a subsequent increase in the blood's pH. Would you expect a person suffering from this condition to hypoventilate or hyperventilate? Explain.

Has a video solution.

Textbook Question

Mrs. Jordan is brought to the emergency room by paramedics, who report that she lost consciousness while at the grocery store. You notice that her respiratory rate is elevated and her breath has a 'fruity' odor. You suspect that she is suffering from diabetic ketoacidosis.
