Circulatory System: Practice
1. A blood cell that starts in the small intestine moves
nutrients to the heart via the __.
2. It enters the heart in the __.
3. Next, it is pumped to the __ and then into the __.
4. It passes through the __ before moving to the __.
5. The blood cell then returns to the heart in the __.
6. It is pumped to the __ and leaves the heart via the
__, where it can be sent anywhere in the body.
Notes – Human Heart
“Each day your
heart beats
about 100,000
times, circulating
blood through
nearly 96,000
kilometers of
blood vessels-roughly onequarter of the
distance to the
moon. Over 70
years, your heart
will beat about
2.5 billion times.”

The Human Heart: Oral Practice
1. A blood cell that starts in the small intestine
moves nutrients to the heart via the __.
2. It enters the heart in the __.
3. Next, it is pumped through a __ to the __.
4. From there it travels through a __ and into the
__.
5. It passes through the __ before moving to the
__.
6. The blood cell then returns to the heart in the
__.
7. It is pumped through a second __ into the __.
8. The blood cell finally leaves the heart through
a second __ into the __ where it can be sent
anywhere in the body.

The heartbeat cycle
Each cycle equals
one heartbeat.
The cycle repeats:
1. Atria and ventricles
relax and fill with
blood
2. Both atria contract to
force blood into
ventricles.
3. Both ventricles
contract to force
blood into aorta and
pulmonary arteries.
Heart Rate
• Heart rate or Pulse the
number of heart beats in
one minute.
– Arteries stretch each time
ventricles contract.
• Heart Beat: caused by
closing of valves. Typically
“lub-dup, lub-dup.”
– Lub = closing of A.V. valves.
– Dup = closing of Semilunar
valves.
• Heart murmurs: hissing
caused by valve defects.
