right atrium and right ventricle
Coronary arteries are about what size in diameter?
1/8 inch
1/3 inch
5/8 inch
1/2 inch
The bicuspid valve is also called the
aortic valve
pulmonary valve
tricuspid valve
mitral valve
The largest chamber of the heart is the
left atrium
left ventricle
right ventricle
right atrium
The two entrance valves of the heart are the
tricuspid and bicuspid valves
mitral and aortic valves
pulmonic and aortic valves
tricuspid and pulmonic valves
Which valves are the semilunar valves?
mitral and tricuspid
aortic and mitral
pulmonic and tricuspid
pulmonic and aortic
What encloses the heart?
epicardium
squamous cell tissue
pericardium tissue
pericardial sac
The pericardium is
the thickest layer of the heart
the fibrous outer fluid filled layer that covers the heart and separates it from the contents of the chest cavity
the partition that separates the right and left side of the heart
the smooth thin layer of the heart
Heart valves are made up of
myocardium
endocardium
pericardium
epicardium
Myocardium is made of
collagen
muscle
adipose tissue
capillaries
The myocardium receives its nourishment from the
pulmonary arteries
aorta
coronary arteries
hepatic portal arteries
What is the myocardium?
heart valves
thin outer layer of the heart
thickest layer of the heart
area between the lungs
What happens when the myocardium is stimulated?
It's muscles contact
It's muscles relax
It's muscle deteriorates
nothing
The apex of the heart is the
broad end of the heart
pointed end of the heart
point where the heart and the aorta come together
part of the heart where the inferior and superior vena cava enter
The apex of the heart is located
just above the diaphragm
between the lungs
on the right side of the chest
near the liver
What does the shape of the heart look like?
It has a point at the top part
It is shaped like a football
It looks like an upside down pear
It opens like a valve and dcloses, when blood comes in contact with it
Where is the base of the heart located?
below the diaphragm
midclavicular just below the 5th intercostal space
on the right side
between the lungs
Why is the left ventricle the largest chamber?
because that side is larger
because it has the job of pumping blood out to all parts of the body
because it receives the most blood
because it goes to the lungs
The right and left side of the heart is separated by the
septum
tricuspid valve
mitral valve
mediastinum
The function of the heart is
to deliver nutrients to body cells
to pump sufficient amounts of blood to all of the cells in the body
to carry fresh oxygen to the body's cells
to take away waste materials from the body
The heart is located
inside the rib cage
in the small of the back
in the center of your chest
in the mediastinum
The size of the normal heart is
about the size of your hand
about the size of your head
about the size of your fist
about half the size of your fist
If the blood supply from the myocardium stops, what happens?
nothing
the area that doesn't receive a blood supply dies
the heart rate speeds up
the patient dies
