Front (Question)

Which side deals with oxygenated blood? Deoxygenated?

Back (Answer)

Right = deoxygenated Left = oxygenated

Front (Question)

What are the functions of the cardio respiratory system?

Back (Answer)

Protection, transportation, regulation, gas exchange, air purifier

Front (Question)

Which chamber is the thickest? Why?

Back (Answer)

Left ventricle, must pump blood to the entire body

Front (Question)

Name the hearts linings from inside, out.

Back (Answer)

Lines the inside of the heart

Front (Question)

What is the myocardium?

Back (Answer)

Heart muscle

Front (Question)

What is the epicardium?

Back (Answer)

Outer lining of the heart

Front (Question)

What is the pericardial sac?

Back (Answer)

Fluid filled sac to reduce friction

Front (Question)

What is systemic circulation?

Back (Answer)

Left side of heart pumps oxygenated blood to body

#20

Front (Question)

What is systole?

Back (Answer)

When ventricles contract (heart empties)

#21

Front (Question)
