4 phases of respiration - CORRECT ANSWERS 1. Pulmonary ventilation
2. External gas exchange
3. Gas transport in the blood
4. Internal gas exchange
Respiration - CORRECT ANSWERS Inhalation and exhalation of air. The process
by which O2 is obtained from the environment and delivered to the cells.
Structures of the Respiratory System - CORRECT ANSWERS Nasal
cavity,Pharynx, Larynx, Trachea, Bronchi, Alveoli
pulmonary ventilation - CORRECT ANSWERS movement of air into and out of
the lungs/exchange of air between the atmosphere and the air sacs (Alveoli)
External gas exchange - CORRECT ANSWERS occurs in the lungs as oxygen
diffuses from the air sacs into the blood and carbon dioxide diffuses out of the
blood to be eliminated
Gas transport in the blood - CORRECT ANSWERS The circulating blood carries
gases between the lungs and the tissues, supplying oxygen to the cells and
bringing back carbon dioxide.
Internal gas exchange - CORRECT ANSWERS occurs in the tissues as oxygen
diffuses from the blood to the cells, whereas carbon dioxide travels from the
cells into the blood
compliance - CORRECT ANSWERS The ease with which one can expand the
lungs and thorax

Diffusion - CORRECT ANSWERS Movement of molecules from an area of higher
concentration to an area of lower concentration/concentration gradient
two phases of ventilation - CORRECT ANSWERS inhalation and exhalation
Surfactant - CORRECT ANSWERS chemical produced in the lungs to maintain
the surface tension of the alveoli and keep them from collapsing
Difference between the left and right bronchi - CORRECT ANSWERS right
bronchi is larger and extends more vertically. (this is where a foreign object will
most likely lodge)
hypoventilation - CORRECT ANSWERS causes increased CO2/H+ in blood &
acidosis
Hyperventilation - CORRECT ANSWERS causes decreased CO2/H+ in blood and
Alkalosis
Part of the brain controls the HR and Resp - CORRECT ANSWERS
Medulla/Brainstem
What is the process that controls respiration - CORRECT ANSWERS The brain
senses arterial levels of H+, sends signals to the phrenic nerve to stimulate the
diaphragm to increases respiration to remove excess CO2 and H+
