Build a flow chart of the path blood takes around your systemic and pulmonary circuits!

Before you jump in, do the questions below to remind yourself about the blood vessels. Choose the right answer from each sentence.
Blood in the pulmonary circuit goes through the
body /
lungs.
Blood in the systemic circuit goes through the
body /
lungs.
Blood is carried away from the heart in
arteries /
veins.
When it reaches the tissues, blood flows into tiny vessels called nutrient vessels or
venules /
capillaries.
The blood pressure is highest in the
pulmonary veins /
systemic arteries.
Now let's go to page 1 and start building the path of blood.

This is a good time to review the basic structure of each side of the heart. Choose the right answer from each sentence.
On each side of the heart, blood is collected in a chamber called an
atrium /
ventricle /
vein.
The blood passes down into the muscular pumping chamber, the
ventricle /
atrium.
To keep the blood from going right back into the chamber it just left, these two chambers are separated by a one-way valve called a/an
atrioventricular valve or AV valve /
semilunar valve.
The blood moves out of the heart into the
veins /
arteries /
To keep blood from dripping back into the heart when it stops pumping, there's another one-way valve on each side. These are called
ventriculoarterial valves /
semilunar valves.
Now you're ready to go on and send the blood through the right heart!
