ALREADY GRADED A+
Which of the following describes cellular respiration?
It is an oxidative catabolic activity
Which of the following types of tissues functions in the covering, lining, and protection of
surfaces and body cavities?
Epithelial tissue
Epithelial tissue functions as the lining and covering of body surfaces and cavities.
The respiratory system is composed of organs that facilitate gas exchange between the
blood and the external environment. Which of the following describes the group of organs
that function during gas exchange
Organ System
A group of organs that work together to perform several related functions is an organ
system.
Which of the following correctly describes the flow of blood through the heart's primary
chambers?
right atrium, left atrium, aorta, and vena cava
right ventricle, left ventricle, aorta, and vena cava
,right atrium, right ventricle, left atrium, and left ventricle
right ventricle, right atrium, vena cava, and aorta
right atrium, right ventricle, left atrium, and left ventricle
Which of the following lists the heart's primary valves in the order in which blood passes
through them?
Tricuspid, bicuspid, aortic semilunar valve, pulmonary semilunar valve
Bicuspid, tricuspid, aortic semilunar valve, pulmonary semilunar valve
Tricuspid, pulmonary semilunar valve, bicuspid, aortic semilunar valve
Tricuspid, aortic semilunar valve, bicuspid, pulmonary semilunar valve
tricuspid, pulmonary semilunar valve, bicuspid, aortic semilunar valve
The condition ________________ can often lead to ________________ due to buildup and
blockage of coronary arteries, preventing blood flow to the myocardium.
arteriosclerosis; myocardial infarction
atherosclerosis; myocardial infarction
,atherosclerosis; stroke
arteriosclerosis; stroke
atherosclerosis; myocardial infarction
Blood pressure is recorded as two numbers, for example 110/70. The top number (110)
represents ___________ blood pressure which is ____________________________.
Systole; the pressure in the blood vessels while the heart is ejecting blood
Systole; the pressure in the blood vessels while the heart is filling
Diastole; the pressure in the blood vessels while the heart is filling
Diastole; the pressure in the blood vessels while the heart is ejecting blood
Systole; the pressure in the blood vessels while the heart is ejecting blood
During systole, a large portion of that blood is pumped out of the ventricle.
In order for the heart to contract, an action potential must be generated at the sinoatrial
node. If this signal fails to reach the Purkinje fibers, what will be the result?
The diastolic period will be shortened
The systolic period will be elongated
, The ventricles will not contract and blood will pool within the heart
The Purkinje fibers will act as pacemaker cells but fire at a slower rate
The Purkinje fibers will act as pacemaker cells but fire at a slower rate
Which of the following lists the blood vessels in the order of blood flow from the left
ventricle back to the heart at the right atrium?
Vena cava, veins, venules, capillaries, arterioles, arteries, aorta
Aorta, arterioles, arteries, capillaries, veins, venules, vena cava
Arterioles, arteries, aorta, vena cava, veins, venules, capillaries
Aorta, arteries, arterioles, capillaries, venules, veins, vena cava
Aorta, arteries, arterioles, capillaries, venules, veins, vena cava
Using the provided image, choose the anatomical structure designated by letter J.
Aorta
The _________________ carries oxygen depleted blood away from the heart, while the
________________ carries oxygen-rich blood back towards the heart.
aorta; pulmonary artery
pulmonary vein; pulmonary artery
