Instead of filling in the blanks with numbers, we use letters. Hidden in one of the columns or rows is the answer to a science question. You’ll find information about the answer on the answer tab below.

The Answer

The question in this edition is:

What bodily system connects the flow of blood between the heart and lungs?

The answer: Pulmonary

The pulmonary system is the part of the body that moves blood from the heart to the lungs and back again. The right atrium of the heart fills with blood depleted of oxygen after supplying oxygen to the rest of the body. The right atrium contracts, sending the blood into another chamber of the heart (the right ventricle). The right ventricle then sends the blood to the lungs to remove waste carbon dioxide and replenish the oxygen. The oxygen enriched blood flows back to the heart’s left atrium. The blood finally travels to the left ventricle, which contracts and sends the oxygen-enriched blood into the arteries that supply oxygen to the rest of the body. Learn more about the pulmonary system from the Franklin Institute in Philadelphia.
