Which of the following statements about blood circulation in
the body is true? - THE CORRECT ANSWER-Valves prevent the back
flow of blood into the atria and ventricles.
Which event occurs first during atrial and ventricular diastole? -
THE CORRECT ANSWER-The atria and ventricles are relaxed, and
blood flows into the atria.
Which event of the cardiac cycle occurs when systolic blood
pressure is measured? - THE CORRECT ANSWER-The ventricles
contract, carrying blood into the aorta, and blood flows into the
relaxed atria.
Which letter indicates systolic pressure? - THE CORRECT ANSWER-a (
at the peak of changes in blood pressure)
Which letter indicates diastolic pressure? - THE CORRECT ANSWER-b
(Where there is a dip in the changes in blood pressure)
,Which letter indicates the arteries? - THE CORRECT ANSWER-d
(Aorta->arteries-> arterioles) (When blood enters the arteries
from the aorta, both pressure and velocity begin to fall. As
blood leaves the arteries and flows through the arterioles, both
pressure and velocity drop rapidly.)
Which letter indicates the venules? - THE CORRECT ANSWER-g
(*From heart*Aorta-> arteries-> arterioles-> capillaries->
venuels-> vein->Venae Cavae*to heart*)
Which letter indicates the vessels in which blood pressure is the
lowest? - THE CORRECT ANSWER-i (the end and where it stays
constant)
Which letter indicates the vessels in which blood velocity is
decreasing the most due to an increase in the total combined
cross-sectional area of those vessels? - THE CORRECT ANSWER-e
(where the slope is decreasing)
Which letter indicates the vessels in which blood travels the
most slowly? - THE CORRECT ANSWER-f (middle of graph and velocity
is constant 0)
Which letter indicates the vessels in which blood velocity is
increasing the most due to a decrease in the total combined
cross-sectional area of those vessels? - THE CORRECT ANSWER-h
(biggest increasing slope)
, Stroke occurs when _____. - THE CORRECT ANSWER-a blood clot
enters the cerebral circulation, blocking an artery and causing
the death of brain tissue
Voice sounds are produced by the _____. - THE CORRECT ANSWER-
larynx
The primary functions of the _____ are to warm, filter, and
humidify air. - THE CORRECT ANSWER-nasal cavity
Which statement about the gas exchange system in fish is
correct? - THE CORRECT ANSWER-It enables oxygen to diffuse from
the water into the blood over the entire length of the gill
capillaries.
Which statement about oxygen in fish gills is correct? - THE
CORRECT ANSWER-The partial pressure of oxygen in blood increases
as it flows through gill capillaries.
The partial pressure of oxygen at a particular point in the
bloodstream is 100 mm Hg. Under what circumstance will
there be a net diffusion of oxygen from the water into the
bloodstream at this location? - THE CORRECT ANSWER-There will be a
net diffusion of oxygen from the water into the bloodstream
only if the partial pressure of oxygen in the water is greater than
100 mm Hg.
_______ in carbon dioxide in your red blood cells, which
causes _____ in pH, causes your breathing to speed up. - THE
CORRECT ANSWER-An increase ... a drop
