valve
left
ventricle
___________
__________________,
the largest and strongest chamber in
the heart. From there, it goes up and
out through the ______________,
the
aorta
largest artery in the body. This vessel
then goes around behind the heart
and digestive organs down through the
trunk
middle of the _______________.
B. The chambers:
atria
atrium
1. The ____________
(singular is ___________)
receive blood from
the body or lungs. They are ______________
and _____________
smaller
thinner
than the other chambers.
2. The ____________________
are the pumping chambers. They
ventricles
large
muscular
are _______________
and ____________________,
and pump
blood out of the ______________
to either the lungs or the body.
heart
2. Blood vessels:
away
A. Arteries carry blood ____________
from the heart. (A= artery, A= away)
The ______________
is the largest artery and comes directly out of the
aorta
heart
_______________
and then branches into _____________
which go to
arteries
the whole body. Arteries carry __________________
blood, except for
oxygenated
pulmonary
the ________________
arteries which go to the
lungs
______________.
Arteries have ________________
muscles
which contract every time the heart beats. This bumping
feeling is the ___________.
pulse
B. Veins carry blood ______
to the heart. They have one-way ______________
valves
that keep blood moving toward the heart. Blood in veins carries
carbon
dioxide
oxygen
__________
_____________
from the cells and is low in ______________.
pulmonary
The one vein that carries oxygenated blood is the __________________
____________
which leads from the ____________
to the _____________.
heart
vein
lungs
The largest veins in the body are the ___________
____________.
vena
cavas
C. Capillaries – Arteries continue to branch, getting smaller and smaller
until they are ________
____________.
Food and oxygen

can then _______________
out of the cells and back into the blood
vessels, which are now called ___________
and direct the blood back

The intersection of the artery and vein where
this diffusion takes place is a ____________________.

capillaries
neck
_____________________
which join with larger vessels that drain into large _________
