Homework 15 Chapter

Question 1A short while after a person has died, a “gasp” of air may occur as the lungs collapse. This flow would represent the

vital capacity.

residual volume.

tidal volume.

expiratory reserve volume.

total lung volume.

Question 2After the trachea, what is the next structure that air passes through?

bronchi

alveolus

pharynx

larynx

bronchioles

Question 3Compared to outside air, describe the air that reaches the lungs.

warmer and with less moisture

cooler and with more moisture

exactly the same

cooler and with less moisture

warmer and with more moisture

Question 4From the inside of the lungs, what is the first cell type the air must pass through to reach the blood?

muscle

simple squamous epithelium

pseudostratified ciliated columnar epithelium

red blood cells

cartilage

Question 5Phillip is breathing at approximately 40 ventilations per minute. What is the respiratory center indicating?

high carbon dioxide concentration in the blood

low oxygen concentration in the blood

low oxygen concentration in the lungs

stretch receptors in the alveolar walls

the firing of the intercostal nerves

Question 6The breathing rate is controlled by chemoreceptors that detect

levels of carbon dioxide in the blood.

level of stretching of the rib muscles and diaphragm.

levels of oxygen in the blood.

levels of carbon dioxide in the alveolar air space.

levels of oxygen in the alveolar air space.

Question 7The vocal cords are found in the

lungs.

bronchi.

larynx.

nose.

pharynx.

Question 8

Which is NOT a association of lower respiratory problems and causes or symptoms?

emphysema—reduced lung and chest volume due to collapsed alveoli and overventilation

chronic bronchitis—ongoing inflammation and possible infection of bronchi with loss of cilia

Pneumocystis carinii—pneumonia caused by a protozoan in absence of a healthy immune system

pulmonary fibrosis—loss of lung elasticity due to breathing silica, coal dust, asbestos, etc.

pulmonary tuberculosis—a bacterial infection that the body tries to isolate and seal off

Question 9Which of the following is an upper respiratory tract disease?

acute bronchitis

pneumonia

cystic fibrosis

pharyngitis

asthma

Question 10You are looking at a structure in the respiratory tract that is filled with small sacs or air pockets. What structure are you looking at?

nose

larynx

alveoli

bronchi

pharynx
