Figure 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.
Based on your experience in the histology lab, examine the image below and identify the correct tissue and correct rationale. O This shows red blood cells based on the lack of structure. O This tissue is lung based on the large air pockets and presence of alveoli. This tissue is bone based on the holes for blood vessels. O This is neural tissue based on the long interconnecting dendrites and axons.
POSSIBLE POIN When people run long distances, their muscles require increased amounts of oxygen. Which system is responsible for carrying this oxygen to the muscles? O Nervous O Respiratory O Digestive O Circulatory 4 5 6 7 8 10 11 12 20 立
O The toxin causes inappropriate firing of neurons leading to periods of rapid twitching that infected individuals experience as surnmation leading to tetanus. QUESTION 6 Mammalian lungs are very different in structure compared to amphibian lungs. The lungs of mammals have highly complex branching patterns of airways. The lungs of amphibians are simpler and more sac-like. Over all, the lungs of mammals are capable of much greater rates of gas exchange compared to amphibians. Why is this? O The more complex structure provides more surface area across which gas exchange can occur. O A complex structure means that gases have more contact time with gases compared to a simpler structure. O Mammalian lungs are usually much bigger relative to their bodies compared to amphibian lungs. O The respiratory membranes of mammals are able to diffuse gases across them much faster than amphibians. QUESTION 7 Click Save and Submit to sve and submit.

Secretions in areas where apocrine glands are located have unpleasant odors because O the odors drive away bacteria that might invade the body. O oxygen cannot easily get to the areas where these glands are located. O bacteria on the skin use the proteins and fats in the secretions as a food source causing the secretions to take on an unpleasant odor. O the mixture of their contents causes the odor.
Oxygen comes from theenvironment and carbondioxide in the end returns tothe environment. How dosmall animals solve theproblem of taking away andbringing these moleculesfrom/to their cells? Why isn'tthat solution possible forlarger animals?

tion Completion Status: accumulation of "waste products" in cells can damage important substances (like collagen) and disrupt normal physiological processes. QUESTION 17 Lungs: With age, lung function becomes "less efficient." Which one does not explain why? Lung tissue becomes more "elastic" resulting in less expansion. O There is a decrease in "reserve capacity" that affects stamina. There is a decrease in the number of airs sacs for oxygen transport. O Muscles in the rib cage become weaker and reduce contraction. QUESTION 18 Which one below does not describe normal age-related changes in the skeletal syste O Loss of bone-density
Which organ is made up of air-carrying tubes and tiny sacs? The diaphragm The stomach O The lungs The rib cage
Watch this animation (http://openstaxcollege.org/l/swallowing) to see how swallowing is a complex process that involves the nervous system to coordinate the actions of upper respiratory and digestive activities. During which stage of swallowing is there a risk of food entering respiratory pathways and how is this risk blocked?
Figure 16.2 When bacteria are destroyed by leukocytes, pyrogens are released into the blood. Pyrogens reset the body’s thermostat to a higher temperature, resulting in fever. How might pyrogens cause the body temperature to rise?
