Concept explainers
To determine:
The justification for the fact that it is impossible to use all of the air in a space in contrast to the fear of the claustrophobic person.
Introduction:
Air is a mixture of gases like nitrogen, oxygen, carbon dioxide, and many more are present in the air. These gases are present in a definite proportion. Alteration in the proportion of gases is known as pollution.
To determine:
The changes in the air when an individual respire and whether these changes are dangerous or not.
Introduction:
Respiration is the biological process including inhaling of fresh air, oxidation of food in the presence of air and exhaling the foul air from the body. Inhaling and exhaling of air together called breathing or external respiration.

- The 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_forwardDue to its partial pressure gradient, carbon dioxide diffuses from cells into tissue fluid and into the ________; in the lungs, carbon dioxide diffuses into the ________. a. alveoli; bronchioles b. bloodstream; bronchioles c. alveoli; bloodstream d. bloodstream; alveoliarrow_forward
- 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_forwardWhich is the order of airflow during inhalation? a. nasal cavity, trachea, larynx, bronchi, bronchioles, alveoli b. nasal cavity, larynx, trachea, bronchi, bronchioles, alveoli c. nasal cavity, larynx, trachea, bronchioles, bronchi, alveoli d. nasal cavity, trachea, larynx, bronchi, bronchioles, alveoliarrow_forwardOf 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_forward
