Human BiologySlide2
A mammalian heart has
___chamber
(s)
One
Two
Three
FourSlide3
In a mammal, blood pressure is lowest in the
Aorta
Vena
cavae
Capillaries of the arm
Veins of the legSlide4
Blood leaves the human heart from:
Left and right atria
Left ventricle only
Right ventricle only
Right ventricle and left ventricleSlide5
The term vasoconstriction refers to
Increasing the size of the lumen of the blood vessel
Decreasing the size of the lumen of the blood vessel
Delivering oxygen and nutrients to the body tissues
Delivering waste products to the kidney for excretionSlide6
Which of the following represents the flow of blood from the heart to the body organs and back to the heart?
Venules
to capillaries to veins to arteries
Arteries to capillaries to veins
Capillaries to arterioles to veins
Veins to arteries to capillaries to arteriolesSlide7
Which of the following chambers of the heart receives blood from the lungs?
Right atrium
Left atrium
Right ventricle
Left ventricleSlide8
This bag is a thin membrane that surrounds the heart.
Visceral pleura
Auricle
Pericardium
ThalamusSlide9
Starting from the right atrium, which of the following is the correct pathway for blood to flow through the human circulatory system?
Mitral valve, right ventricle, pulmonary vein, aorta
Right ventricle, pulmonary artery, left atrium, aorta, left ventricle
Tricuspid valve, right ventricle, pulmonary artery, left atriumSlide10
Systemic circulation refers to the circulation of blood:
To the lungs and back
Within the brain
Throughout the body
Within the heartSlide11
True/False: The left side of the heart pumps the same amount of blood as the right.
True
FalseSlide12
True/False: An obstruction in the superior vena cava would decrease the flow of blood from the head and neck to the heart.
True
FalseSlide13
Which of the following are involved directly in the pulmonary circulation?
Superior vena cava, right atrium and left ventricle
Right ventricle, pulmonary artery and left atrium
Left ventricle, aorta and inferior vena cava
Right atrium, aorta and left ventricleSlide14
The second heart sound, described as “dub” is actually the
Atria contracting
Ventricles contracting
Atrioventricular
valves closing
Semilunar valves closing
Heart slapping the liverSlide15
The tricuspid valve is closed
While blood flows from the right ventricle to the pulmonary trunk
While blood flows from the atrium to the ventricle
By the movement of blood from the superior vena cava to the right atrium
While the atrium is contractingSlide16
The valve located between the left atrium and left ventricle is the
Aortic semilunar valve
Bicuspid (mitral) valve
Pulmonary semilunar valve
Tricuspid valveSlide17
Strong connective tissue strings that are attached to papillary muscles and to the cusps of the
atrioventricular
valves are
Musculi
pectinati
Traveculae
carnae
Chordae
tendinae
The
interventricular
septumSlide18
Which statement best describes arteries?
All carry oxygenated blood to the heart
All carry blood away from the heart
All contain valves to prevent the backflow of blood
Only large arteries are lined with endotheliumSlide19
Select the correct statement about the heart valves
The mitral valve separates the right atrium from the right ventricle
The tricuspid valve divides the left atrium from the left ventricle
Aortic and pulmonary valves control the flow of blood into the heart
The AV valves are supported by the chordae
tendinae
so that no regurgitation of blood into the atria occursSlide20
Blood within the pulmonary veins returns to the _____.
Right atrium
Left atrium
Right ventricle
Left ventricleSlide21
Which vessel(s) of the heart receive(s) blood during right ventricular contraction?
Vena cava
Pulmonary trunk
Aorta
Pulmonary veinsSlide22
The nose serves all the following functions except
As a passageway for air movement
As the initiator of the cough reflex
Warming and humidifying the air
Cleansing the airSlide23
Surfactant helps to prevent the alveoli from collapsing by
Humidifying the air before it enters
Warming the air before it enters
Interfering with the cohesiveness of water molecules, thereby reducing the surface tension of alveolar fluid
Protecting the surface of alveoli from dehydration and other environment variationsSlide24
The respiratory membrane is a combination of
Respiratory bronchioles and alveolar ducts
Alveolar walls, alveolar space and capillary walls
Atria and alveolar sacs
None of the aboveSlide25
The pleurae are vital to the integrity of the lungs because they
Contain cilia that protect the lungs
control the volume of the lungs
Secrete a lubricating serous fluid, allowing the lungs to glide over the thoracic wall during breathing
Maintain the proper temperature of the lungs during sleep
