Bio 2301 exam 3 comprehensive
Questions and Answers with Verified
Solutions
Question 1:
the body system responsible for maintaining the pH of the blood is
Answer:
both the respiratory and urinary systems
Question 2:
cellular respiration will produce which of the following byproducts?
Answer:
carbon dioxide
Question 3:
the kidneys alter levels of _______to regulate the acid-base balance in
the blood.
Answer:
Hydrogen ions (H+)
Question 4:
true or false: by increasing the respiratory rate, the body can raise the pH
of the blood by eliminating carbon dioxide?
Answer:
true
,Question 5:
when a person is exercising, which of the following would occur:
Answer:
Decrease in oxygen in the blood, increased carbon dioxide in the blood
and increase in hydrogen ions.
Question 6:
Boyle's law states that the pressure of a gas varies inversely with volume.
therefore, if the volume of the chamber holding the gas decreases, the
pressure will?
Answer:
increase
Question 7:
Boyle's law states that the pressure of a gas varies inversely with volume.
therefore, if the volume of the chamber holding the gas increases, the
pressure will?
Answer:
decrease
Question 8:
changing pressure is important, because gases will flow from high
Answer:
air would flow into the lungs
, Question 9:
changing pressure is important, because gases will flow from high
pressure to low pressure. if pressure inside the lungs increased to a level
higher than that of the atmosphere, then:
Answer:
air would flow out of the lungs
Question 10:
Knowing that air flows from high to low pressure and changes in volume
cause changes in pressure (due to Boyle's law), then which of the
following would you expect to cause inhalation?
Answer:
an increase in volume of the lungs
Question 11:
gases move down a concentration gradient, from an area of higher
concentration to an area of lower concentration. the concentration of a
gas is determined by its partial pressure, because air is a mixture of
gases. which way does oxygen move?
Answer:
there is a higher partial pressure of oxygen in the alveolar air than the
venous blood, so it moves from the air to the blood.
Question 12:
Boyle's law states that an increase in volume leads to:
Answer:
A decrease in pressure
