Chapter 22 Part 2

Pulmonary interstitial tissue contains

• type 1 pneumocytes

• type 2 pneumocytem

• elastin

• endothelial cells

Gas exchange between blood and the lungs is referred to as

• Pulmonary ventilation

• External respiration

• Internal respiration

According to Boyle's law, as volume increases

• pressure increases

• pressure decreases

• pressure remains constant

Flexion of the diaphram allows for

• Inspiration

• Expiration

• Forced expiration

Flexion of the diaphram results in

• P(atm) > P(intra-alveolar)

• P(atm) < P(intra-alveolar)

• P(intra-pleural) > P(intra-alveolar)

Forced inspiration would involve

• the diaphragm only

• external intercostals and the diaphragm

• the diaphragm, external intercostals, SCM, scalene, pec minor, and serratus anterior

• the diaphragm, internal intercostals, and abdominal muscles
