BSC 2086 Final Questions and Answers
1. If you remember, as you travel down the respiratory system, you have an area where you have the end of the
conducting zone and that ends with what particular item?: The terminal bronchioles.
2. Which one of your types of cells secretes a fluid containing surfactant?: -
Type two cells.
3. When you look at the walls of the alveoli, they are composed primarily of a single layer. You want to have it
thin so that you get better diffusion of your gases. Those single layer of squamous epithelial cells are called what?:
Type one cells.
4. Your air and food get routed into the proper channels by what organ?: The larynx.
5. What is exchanged during normal breathing, just like the tides of an ocean when it comes in and out?: The
tidal volume.
6. The lung volume that represents the total maximum volume of exchange- able air?: Vital capacity.
7. What is not a stimulus for breathing?: Rising blood pressure
8. What is the pressure within the alveoli of the lungs?: Intrapulmonary pressure
9. Your oxygen and carbon dioxide diffusion is more effective when you have a thin layer of tissue it's going
through, because the mechanism it's using is what?: Diffusion
10.What respiratory associated muscle will contract, if you were to blow up a balloon?: Internal intracoastal and
abdominal muscles
11.What structure is not found on the right lobes of the lungs, but is on the left?: The cardiac notch
12.What gives you the greatest total surface area for gas exchange?: The alveoli
13.Whicn law is P1V1 = P2V2?: Boyle's Law
14.What are the factors responsible for holding the lungs to the thorax wall?-
: .That negative section pressure that you have in the intrapleural space.
.Your surface tension in the pleural fluid.
15. As you look at the branches coming down the respiratory system after your tertiary bronchus, the next
smaller branch of the respiratory passageway is the?: Bronchioles
16.What is the first bronchiole that you encounter, it terminates the conduct- ing zone?: Terminal bronchioles
17.The next bronchiole is called what? It's the start of the respiratory zone.: -
Respiratory bronchiole
18.The pleura are vital to the integrity of the lungs because they?: Produce a lubricating serious secretion
allowing the lungs to glide over the thorax
