I Choose | It is also called windpipe. It connects the larynx and the bronchi. [ Choose J These are the major organs of respiratory system. These are infoldings of the body surface which contain alveoli. [ Choose J These secretions coat the surface of the alveoli. [ Choose ) > > >
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 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 16 Which of the following is essential for the proper functioning of the lungs? O optimal body temperature O diffusion of carbon dioxide from cells O essential nutrients from our diet sufficient oxygen O adequate atmospheric pressure
QUESTION 2 The chest wall transmural pressure Atmospheric pressure (Patm) = 760 mmHg F Thoracic wall [D G 756 760 Lung A Diaphragm Alveolar pressure (Paly) equals -4 mm Hg equals 0 mm Hg cannot be determined by the information provided in this figure equals +4 mm Hg

bronchioles [ Choose] (Choose] lead to the alveolar ducts, which terminate in the alveoli cilia thin, sensitive structures where actual gas exchange occurs in lungs area that includes the lingual and palatine tonsils at back of mouth includes the visceral and parietal membranes around lungs cellular structures that propel mucus & particles toward pharynx alveoli 1. TChoose ] pleura [ Choose] oropharynx [ Choose ]
Question 12 Which of the following about the pleural sacs is incorrect? O Provide lubrication between moving organs O Compartmentalize thoracic cavity O Comprised of triple-layered membrane of stratified squamous epithelium O Intrapleural pressure keeps lungs partially expanded at all times O One sac per lung, which are stuck to lung, chest wall, and diaphragm • Previous
Question 29 Find us The partial pressures of in venous and arterial blood in the pulmonary circulation is O A. Oxygen, 46 mmHg, 40 mmHg O B. Carbon dioxide, 40 mmHg, 46 mmHg O C. Oxygen, 40 mmHg, 46 mmHg O D. Carbon dioxide, 46mmHg, 40 mmHg OE. Oxygen, 100 mmHg, 150 mmHg and
QUESTION 38 Which of the following statements is FALSE? O C The partial pressure of O2 in the alveoli is higher than it is in the pulmonary capillaries so O2 diffuses from the alveoli to the pulmonary capillaries. The partial pressure of CO2 in the alveoli is 40 mm Hg and in the pulmonary capillaries it is 46 mm Hg. Although this is not a big pressure gradient, CO2 is very soluble so it diffuses from the pulmonary capillaries to the alveoli where it then is exhaled. The partial pressure of O2 in the systemic capillaries is higher than it is in the body cells so O2 diffuses from the systemic capillaries to the body cells. The partial pressure of CO2 in the systemic capillaries is higher than it is in the body cells so CO2 diffuses from the systemic capillaries to the body cells. 0
