This is an advantage of air being the
respiratory medium as opposed to
water.
Q: What is
a higher oxygen concentration/being easier to
pump?
S2C06 Jeopardy Review
This is an advantage to water
being the respiratory medium
instead of air.
A: What is keeping respiratory cells
moist?
S2C06 Jeopardy Review
The uptake of O and the discharge
of CO .
A: What is gas exchange?
S2C06 Jeopardy Review
Characteristics that maximize gas
exchange across respiratory surfaces?
A: Thin, moist, large surface area
S2C06 Jeopardy Review
Outfoldings of the body surface that
are suspended in water; used by many
aquatic animals for gas exchange
A: What are gills?
S2C06 Jeopardy Review
Respiratory organs used by terrestrial
animals; all respiration occurs in one
place
A: What are lungs?
S2C06 Jeopardy Review
The simplest animals (sponges,
cnidarians, and flatworms)
respirate this way.
A: The gases diffuse across the
membrane of every cell in the body.
S2C06 Jeopardy Review
Branched air tubes that extend to
every section in the body, used by
insects for respiration
A: What is tracheal system/trachea?
S2C06 Jeopardy Review
Process by which earthworms and
amphibians respirate
A: What is they respirate across their
entire outer skin?
S2C06 Jeopardy Review
What is the inhalation and
exhalation of air?
A: Breathing…seriously.
S2C06 Jeopardy Review
The type of pressure by which
amphibians respirate that involves
drawing air into the oral cavity,
then forcing it down the trachea.
A: What is positive pressure?
S2C06 Jeopardy Review
The type of pressure by which
mammals respirate…PULLING air
into the lungs.
A: What is negative pressure?
S2C06 Jeopardy Review
The part of the brain that sets
breathing rhythms based on the
pH in the brain fluid
A: What is the medulla (oblongata)?
S2C06 Jeopardy Review
The adaptation that allows birds
to renew air in lungs and have
higher oxygen concentrations
A: What are air sacs? (posterior
and anterior)
S2C06 Jeopardy Review
Type of blood vessels that circulate gas from
the high pressure lungs to the heart
A: What are pulmonary veins?
S2C06 Jeopardy Review
Type of blood vessels that circulate
gases from heart to low pressure tissue
cells
A: What are arteries?
S2C06 Jeopardy Review
The most abundant oxygen
transporting respiratory
pigments
A: What are hemoglobin and hemocyanin?
S2C06 Jeopardy Review
The proportion of atmospheric
pressure contributed by a single
gas.
A: What is partial pressure?
S2C06 Jeopardy Review
The reason more carbon dioxide
causes hemoglobin to release the
oxygen bound to it.
A: The drop in pH caused by
presence of CO2.

Extremely active mammals
consume large amounts of this
gas.
A: What is oxygen?
S2C06 Jeopardy Review
Gas besides oxygen that
hemoglobin transports.
A: What is carbon dioxide?
S2C06 Jeopardy Review
Type of air sacs that push stale
oxygen out of bird lungs
A: What are anterior air sacs?
S2C06 Jeopardy Review
Diving mammals use this to
store oxygen in the blood

explanation of countercurrent
exchange.
An
A: Blood and water move in opposite
directions. As blood gains more
oxygen, it encounters water with everhigher concentrations of oxygen, so
