- Figure 16.9 Which of the following statements about the human respiratory system is false? a. When we breathe in, air travels from the pharynx to the trachea. b. The bronchioles branch into bronchi. c. Alveolar ducts connect to alveolar sacs. d. Gas exchange between the lungs and blood takes place in the alveolus.The respiratory system_______. a. provides body tissues with oxygen b. provides body tissues with oxygen and carbon dioxide c. establishes how many breaths are taken per minute d. provides the body with carbon dioxidewhy does lower atmospheric pressures make it harder to breathe at high altitude.
- What is the answer of this. Human respiratory system.BASED ON THE TEXT, what is meant by "semipermeable membrane" and why is it necessary to gas exchange between O2 and CO2? USE THIS SENTENCE STARTER : a semipermeable membrane means.... A semipermeable membrane is needed for exchange of oxygen and carbon dioxide because...Oxygen is picked up in the pulmonary ___ beds
- How can problems with ventilation could affect someone's ability to carry out cellular respiration. *Why does altitude have almost no effect on an animal’s ability to rid itself of CO2 through gas exchange?Can you answer all the parts to this question regarding fish A: Describe countercurrent exchange in your own words. B: Describe concurrent exchange in your own words. C: Mammals have dead end sacs called “alveoli” and don’t have the super efficient countercurrent exchange system seen in fish. Why do you think countercurrent exchange is necessary for fish? (hint: think about the difference between where most mammals and fish live).
