QUESTION 6 The total oxygen content (toial concentration) of the venous blood is measured only by central chemoreceptors in the medula measured onty by peripherel chemoreceptors not directly measured by any of the chemoreceptors QUESTION 7 A reflexive decrease in ventfilation would he caused by ia of the arlerial blood Rise in the carbon dloxide level Increase in the pH Decrease in the Decrease in the pH PO2 QUESTION 8 Chemoreceptors on the ventral surface of the medula oblongata respond to changes in the oxygen level of the arterial blood carbon dioxide level of the arterial blood oxygen level of the venous blood pH of the venous blood QUESTION 9 Joe frequently experiences dyspnea due to his severe emphysema. His difficulty in pulmonary ventilation results from His total lung volume is too small due to the growth of fibrous tissue around his alveoi. The resistance to airflow in his trachea is increased and his inspiratory muscles are unable to draw air in His small branchioles collapse during expiration and air too much air remains trapped in his lungs. There is a hole in his visceral pleura and part of his lung has collapsed QUESTION 10 Voluntary apnea (breath-holding) for 60 seconds will: Decrease alveolar pCO2 Increase arterial p02 Inhibit the arterial increase alveolar pCO2 chemoreceptors Cliek Save and Submit to save and submit.
