Question
Chapter 47, Problem 1.5A
Summary Introduction
To fill:
The correct term in the given blank.
Introduction:
Breathing rate is defined as the number of breaths taken by a person in a minute. It is controlled by the breathing center present in the pons and the medulla oblongata in the brain. The pH of the blood and the concentration of oxygen and carbon dioxide primarily affects the breathing rate of a person.

- Underwater, we humans cant compete with whales and other air-breathing marine mammals, which can stay submerged for extended periods. At the beach one day you meet a surfer who tells you that special training could allow her to swim underwater without breathing for an entire hour. From what you know of respiratory physiology, explain why she is mistaken.arrow_forwardThe respiratory components of the medulla consist of which of the following? Dorsal respiratory group Apneustic center Ventral respiratory group Pneumotaxic center 1 only 2 only 1 and 3 only 2 and 4 onlyarrow_forwardA partial pressure gradient of oxygen exists between ________. a. air and lungs b. lungs and metabolically active tissues c. air at sea level and air at high altitudes d. all of the abovearrow_forward
- We inhale oxygen when we breathe and exhale carbon dioxide. What is the oxygen used for and where does the carbon dioxide come from?arrow_forwardGas exchange that occurs at the level of the tissues is called ________. external respiration inteipulmonarv respiration internal respiiation pulmonary ventilationarrow_forwardBreathing _______. a. ventilates the lungs b. draws air into airways c. expels air from airways d. causes reversals in pressure gradients e. all of the abovearrow_forward
- Of the following, which does not explain why the partial pressure of oxygen is lower in the lung than in the external air? Air in the lung is humidified; therefore, water vapor pressure alters the pressure Carbon dioxide mixes with oxygen Oxygen is moved into the blood and is headed to the tissues Lungs exert a pressure on the air to reduce the oxygen pressure.arrow_forwardWhen you sneeze, abdominal muscles abruptly contract, pushing your diaphragm upward. Given the discussion of the respiratory cycle in Section 10.4, why does this change expel air out your nose?arrow_forward
