- Test Your Understanding 1. Which of the following is a benefit of gas exchange in air compared with gas exchange in water? (a) air has a higher concentration of molecular oxygen (b) oxygen diffuses more slowly in air (c) no energy is required for ventilation (d) moist respiratory surface is not needed (e) air is denser than waterarrow_forwardTest Your Understanding 13. INTEREPT DATA Look at Figure 46-10b. How would strenuous muscle activity affect the oxygenhemoglobin dissociation curve? (Hint: How does muscular activity affect pH? See Chapter 40 if you need to review this concept.) Figure 46-10 Oxygen-hemoglobin dissociation curvesarrow_forwardUnderwater, we humans cant compete with whales and other air-breathing marine mammals, which can stay submerged for extended periods. At the beach one day you meet a surfer who tells you that special training could allow her to swim underwater without breathing for an entire hour. From what you know of respiratory physiology, explain why she is mistaken.arrow_forward
- What is the difference between respiration and breathing; please write an essay.How much does the sky weigh?What makes a rainbow?Why don't birds get electrocuted when they land on an electric wire?That is all, thank you!arrow_forwardCompare the two types of gas exchange systems in invertebrates. Based on your observation of the tracheal system of an aquatic insect: mosquito wriggler) & book lung systems (in invertebrates: spider (Araneae), explain how these systems are similar and how they differ from one another. (i.e. structures involved & relation to circulatory system). In cockroach, do the spiracles occur in pairs? What do you think happens if you block oxygen from coming into the body and prevent carbon dioxide from leaving?arrow_forwardWhy does altitude have almost no effect on an animal’s ability to rid itself of CO2 through gas exchange?arrow_forward
- Compare respiration among flatworms, insects, fish, and mammals.arrow_forwardDescribe some structural and functional features that are commonto all gas-exchange surfaces in animals.arrow_forwardCompare and contrast how gas exchange is carried out in insects and humans. How does this relate to the type of circulatory system in these two types of animals?arrow_forward
- Describe the respiratory system of birds and how it allows oxygen-rich air to enter the lungs during both inhalation and exhalation.arrow_forwardFigure 39.7 Which of the following statements about the mammalian respiratory system is false? When we breathe in, air travels from the pharynx to the trachea. The bronchioles branch into bronchi. Alveolar ducts connect to alveolar sacs. Gas exchange between the lung and blood takes place in the alveolus.arrow_forwardFigure 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.
