Explain why slow, deep breathing ventilates the alveoli better than rapid, shallow breathing. Changes in pulmonary elastic and resistive properties, and in maximum expiratory flow with increasing age, were first described 40 yrs ago, admittedly by small cross-sectional studies of young adults versus elderly subjects. Inhaling air with 17% O2 caused arterial PO2 to decrease to 80 mmHg. Clinical studies indicate that minute ventilation starts increasing exponentially once arterial PO2 is reduced to 60 mmHg. Explain why, Hypothesize what might happen to the reserve volumes (IRV and ERV) when you exercise. The _________________ the maximum amount of air that the lungs can accommodate. Use this information to explain why these individuals have low heart rates combined with increased PR intervals. Lungs are the paired organs that are located on either side of the chest. a. These gases are exchanged with the atmosphere when you breathe. Be sure to relate your response to tidal volume. How is air transported to the lungs? Describe the pulmonary ventilation process of inspiration and expiration. Explain how inhalation and exhalation change the volume pressure. During exercise there is an increase in cardiac output, which corresponds to an increase in maximal oxygen consumption. The increase in RV that occurs causes a corresponding decrease in ERV and IRV. During exercise: IRV will decrease. Therefore the main factors impacted in chronic adaptation to exercise are blood flow, and oxygen extraction in the tissues. In contrast, when you take a deep breath and exhale, the amount of air expelled from your lungs is known as vital capacity, the very most your lungs can hold.
