Which one is true?

1. the atria are below the ventricles
2. the ventricles are below the atria

Which half of the heart is oxygen-poor and which one oxygen-rich?

1. Left side oxygen-poor, right side oxygen-rich
2. Right side oxygen-poor, left side oxygen-rich

Which valve is on the left and which one is on the right?

1. Left: bicuspid valve, right: tricuspid valve
2. Right: bicuspid valve, left: tricuspid valve

The aortic valve sits between...

1. the left ventricle and the aorta
2. the right ventricle and the aorta

The pulmonary valve sits between...

1. the left ventricle and the pulmonary artery
2. the right ventricle and the pulmonary artery

Make a sentence!

1. Heart                         blood                                     all the other organs ________________________________________________________________

2. Tricuspid valve              right atrium                          right ventricle  ________________________________________________________________

3. Septum                   oxygen-poor blood          oxygen-rich blood

    ________________________________________________________________

Combining the systemic with the pulmonary circulation:

1. from heart to tissues, to heart, to lungs, to heart
2. from tissues to lungs, to heart, to lungs, to heart

oxygen-rich = "oxygenated"

oxygen-poor = "deoxygenated"

Cardiac circulation: 

around the outside of the heart itself

Systemic circulation

Pulmonary circulation

From heart to the tissues and cells and back to the heart

From heart to the lungs and  back to the heart
