- Question 39 At FRC the alveolar pressure is OA. Equal to plural pressure OB. Equal to atmospheric pressure OC. More negative that plural pressure OD. Less than atmospheric pressure O E. Greater than atmospheric pressureQUESTION 7 This will cause a pressure gradient to occur causing air to move into the lungs. Intrapleural pressure becoming less than atmospheric pressure Intrathoracic pressure decreasing interpulmonic pressure Intrapulmonic pressure increasing intrapleural pressure Intrapulmonic pressure becoming less than atmospheric pressure OOQUESTION 26 Which statement regarding the figure is correct? Atmospheric pressure (Patm) 760 mmHg -F Thoracic wall D 756 В 760 Lung Diaphragm Alveolar pressure (Paly) The transmural pressure labeled A will always be a positive value The alveolar pressure causes the pressure labeled D to change O The pressure labeled B is equal in magnitude to the chest wall recoil The transmural pressure labeled C is opposing the lung recoil
- Question 5 2. During inspiration, how does the partial pressure of oxygen in the alveoli changes relative to the deoxygenated blood in the lung capillaries to enable diffusion of oxygen across the alveolar membrane? (Mention if the partial pressure of oxygen is increased or decreased in the alveoli compared to capillary deoxygenated blood during inspiration, and how that affects oxygen diffusion across the alveolar membrane).Question 28 de cad O C. Systemic arterial PCO2 O D. Pulmonary arterial PO2 O E. Respiratory quotient (R) JARACA The alveolar gas equation is used to determine the partial pressure of alveolar oxygen by using a measure of the O A. Systemic arterial PO2 OB.
