What is pulmonary ventilation? - ANS movement of gases into and out of the lungs
What is ventilation between? - ANS external environment and lungs
What is inhalation? - ANS air moving from the external environment into the lungs
during inhalation, O2 __ and CO2 ___ air is moved into the lungs - ANS rich, poor
during exhalation, O2 ___ and CO2 ___ air are removed from the lungs - ANS poor, rich
What is exhalation? - ANS air moving from the lungs to the external environment
What is respiration? - ANS exchange of gases across a membrane into and out of a blood
vessel
during respiration, CO2 diffuses from the capillary blood into the ___ while oxygen diffuses from
the lungs into the ___ - ANS lungs, capillary blood
what is tissue respiration - ANS exchange of O2/CO2 between the blood in the systemic
capillaries
What is the cellular respiration equation? - ANS C6H12O6 + 6O2 --> 6CO2 + 6H2O + ATP
What happens to oxygen during external respiration? - ANS moves from the alveoli across the
alveolar membrane into the pulmonary capillary bed
What happens to carbon dioxide during external respiration? - ANS moves from the capillary
bed across the alveolar membrane into the alveoli
What happens to carbon dioxide during internal respiration? - ANS moves from the interstitial
fluid across the systemic capillary membrane into the systemic capillary bed
What happens to oxygen during internal respiration? - ANS moves from the systemic capillary
bed across the systemic capillary membrane into the interstitial fluid where it is used to create
ATP
, What are the functions of the respiratory system? - ANS communication, olfaction, pH balance,
blood pressure regulation, filtration of blood, production of platelets, promoting blood and lymph
flow
How is communication involved in the respiratory system? - ANS involved in speech,
vocalization, crying, and laughing
How is olfaction involved in the respiratory system? - ANS site for smelling
How is the pH balance involved in the respiratory system? - ANS control the levels of CO2
How is blood pressure regulation involved in the respiratory system? - ANS lungs are
responsible for producing ACE which is involved in the production of angiotensin II
what is angiotensin II - ANS hormone that assists in blood pressure regulation and promotes
the release of aldosterone
How is filtration of blood involved in the respiratory system? - ANS the lungs are capable of
filtering small blood clots in the blood
How is the production of platelets involved in the respiratory system? - ANS body's platelets are
generated from megakaryocytes in the lungs not bone marrow
How is promoting blood and lymph flow involved in the respiratory system? - ANS breathing
and muscle contractions helps to promote the movement of blood and lymph
True or false: gas molecules move down their pressure gradient, from high to low gas pressure -
ANS true
Which of the following is the movement of gases into and out of the lungs? - ANS ventilation
True or false: oxygen is created during respiration - ANS false
True or false: CO2 is created during cellular respiration - ANS true
What prevents the trachea from collapsing? - ANS C-shaped cartilaginous rings
What structure is also known as the "voice box"? - ANS larynx
Which bone does not contain a paranasal sinus? - ANS mandible
What are the principal components of the respiratory system? - ANS nose, pharynx, larynx,
trachea, lungs
