Why? Your Answer:When we swallow the epiglottis moves to block the entrance of food particles into our larynx and lungs. The muscles of the larynx pull upward to assist with this movement. They tightly close during swallowing. This prevents food from entering our lungs.The trachea is closed by the epiglottis. The epiglottis moves inferiorly, covering the trachea. This is to prevent food or liquid from entering the lungs.Biod 151/A&P 1 Module 2 Exam Portage Learning Latest Update 2022/2023The pleurae are membranes that coverNote: Essay answers must clearly be in your own words.Explain at least two differences between Type I and Type II alveolar cells. Your Answer:The type I cells is a complex branched cell with multiple cytoplasmic plates that are greatly attenuated and realatively devoid of organelles. Type I cells the very thin simple squamous epithelium of the alveoli junction with capillaries. Make up roughly 95 % of aleveolar epithelial cells.The Type II cells act as the 'caretaker' of the alveolar compartment. Type II produce and secrete pulmonary surfactant which is needed throughout the alveolar surface to keep the alveoli open. In addion, Type II cells can divide to replace damaged Type I cells.Make up roughly 5% of alveolar epithelial cells.Type I form the very thin simple squamous epithelium of the alveoli in junction with capillaries.

What is the partial pressure of oxygen (in mmHG) if nitrogen is 300 mmHg and carbon dioxide is 350 mmHg? To receive full credit you must show your work.Biod 151/A&P 1 Module 2 Exam Portage Learning Latest Update 2022/2023Your1 atm = 760 mmHg300 mmHg+350 mmHg + X = 760 mmHgX = 110mmHg 110 mmHG1atm= 760 mmHg300 mmHg + 350 mmHG + X =760 mmHg OR: =110 mmHGWhy would warming air be beneficial to gas exchange? Your Answer:The higher temperature the greater gas volume, or the lower temperature the lower gas volume. That's mean is Charles's Law. According to Charles's Law, the volume of a given quantity of gas is directly proportional to its temperature. Therefore the weather when be warm, gas volume greater. Warm air helps keep our lungs expanded in alveoli full and open and gas exchange can take place.It would expand the air to make it more available for gas exchange.Biod 151/A&P 1 Module 2 Exam Portage Learning Latest Update 2022/2023YourExplain why incomplete ventilation is important for effective gas exchange. Your Answer:It helps to conserve water and to maintain a constant temperature within the lungs. Because of incomplete ventilation the air entering mixes with used air remaining in the lungs. Thus, temperature allows for greater gas exchange.Incomplete ventilation helps to maintain a constant temperature within the lungs. The increased temperature allows for greater gas exchange.From widest to narrowest, the branches of the bronchial tree are: Secondary bronchi, tertiary bronchi, primary bronchi, bronchiolesBiod 151/A&P 1 Module 2 Exam Portage Learning Latest Bronchioles, primary bronchi, secondary bronchi,Tertiary bronchi, secondary bronchi, primary bronchi, bronchiolesPrimary bronchi, secondary bronchi, tertiary bronchi, bronchiolesIn gas exchange (external respiration):Carbon dioxide diffuses from alveoli into capillaries, oxygen diffuses from capillaries into alveoli
