4 phases of respiration - correct answer✔✔1. Pulmonary ventilation
|||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\
2. External gas exchange
|||\\\ |||\\\ |||\\\
3. Gas transport in the blood
|||\\\ |||\\\ |||\\\ |||\\\ |||\\\
4. Internal gas exchange
|||\\\ |||\\\ |||\\\
Respiration - correct answer✔✔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 answer✔✔Nasal cavity,Pharynx, Larynx,
|||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\
Trachea, Bronchi, Alveoli |||\\\ |||\\\
pulmonary ventilation - correct answer✔✔movement of air into and out of the |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\
lungs/exchange of air between the atmosphere and the air sacs (Alveoli) |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\
External gas exchange - correct answer✔✔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 answer✔✔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 answer✔✔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 answer✔✔The ease with which one can expand the lungs and thorax |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\
Diffusion - correct answer✔✔Movement of molecules from an area of higher concentration to
|||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\
an area of lower concentration/concentration gradient
|||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\
two phases of ventilation - correct answer✔✔inhalation and exhalation
|||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\
Surfactant - correct answer✔✔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 answer✔✔right bronchi is larger and |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\
extends more vertically. (this is where a foreign object will most likely lodge)
|||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\
hypoventilation - correct answer✔✔causes increased CO2/H+ in blood & acidosis |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\
Hyperventilation - correct answer✔✔causes decreased CO2/H+ in blood and Alkalosis |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\
Part of the brain controls the HR and Resp - correct answer✔✔Medulla/Brainstem
|||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\
What is the process that controls respiration - correct answer✔✔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+ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\
Hydrogens role in respiration - correct answer✔✔Hydrogen stimulates the central |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\
chemoreceptors in the brain stem to either increase or decrease the rate and Depth of |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\
