Across:

.

3. Describe what happens in the heart
during diastole.
Atria contract and push blood into the ventricles.
4. Describe what happens in the heart during
systole. State where each ventricle sends the
blood.
right ventricle pushes blood into pulmonary artery so blood goes
to the lungs, left ventricle pushes blood into the aorta so blood goes
to all parts of the body.
• 5. List the parts of the conductive pathway for
electrical impulses in the heart. List the parts in
correct order.
( SA) node, pathways in the atria, atrioventricular (AV)
node, bundle of His, right & left bundle branches,
Purkinje fibers
1 The SA
node sets
the rate
and rhythm
of your
heartbeat
2
The SA node fires
an impulse. The
impulse spreads
through the walls
of the right and
left atria, causing
them to contract.
This forces blood
into the ventricles.
3 The impulse
travels to the AV
node. Here, the
impulse slows
for a moment
before going on
to the ventricles
.
4 The impulse travels
through a pathway of
fibers called the HISPurkinje network. This
network sends the
impulse into the
ventricles and causes
them to contract. This
forces blood out of the
heart to the lungs and
body.
5 The SA node
fires another
impulse.
The cycle begins
again
.
• 6. What is arrhythmia? How is it
diagnosed?
abnormal heart rhythm; cardiac monitors &
electrocardiogram
7. Identify the following blood vessels
• A. blood vessels that carry blood away from the heart:
B. Blood vessels that carry blood back to the heart:
• C. Blood vessels that connect arterioles with venules.
• D. Largest artery in the body.
• E. Two largest veins in the body.
• F. Vessels that allow oxygen & nutrients to pass through to
cells.
• G. Smallest branches of arteries.
• H. Smallest branches of veins.
• I. Vessels that contain valves to prevent backflow of blood.
• J. Most muscular & elastic blood vessels.

11. What gives blood its
characteristic red color?
• Hemoglobin and the amount of oxygen
present.
12. What is hemoglobin? What
is its function?
• Hemoglobin is a complex protein found
on the red blood cell; and its function is
to carry oxygen and carbon dioxide.
13. Identify the type of leukocyte(s)
that performs the following function.
phagocytize bacteria
neutrophils &/or
monocytes
