   Your Hardworking Heart

   Make a fist. That is about the size of your heart. This strong muscle sits in the middle of your chest, tilted slightly to the left. It beats about 100,000 times a day without ever taking a break. In one day, it pumps enough blood to fill about forty bathtubs.

   A Pump with Four Rooms

   The heart has four chambers. The two upper chambers are called atria. They receive blood as it returns to the heart. The two lower chambers are called ventricles. They squeeze hard to push blood out. A wall of muscle divides the right side of the heart from the left side.

   Diagram caption: Blue arrows show blood that needs oxygen. Red arrows show blood that is rich in oxygen.

   Two Trips for Every Drop

   Blood travels on two loops. On the first loop, the right side of the heart pumps blood to the lungs. There, the blood picks up oxygen and drops off carbon dioxide. On the second loop, the left side pumps the oxygen-rich blood to the rest of the body. Then the blood returns to the right side of the heart to begin again. The left ventricle has the thickest wall because it pushes blood the farthest.

   Doors That Keep Blood Moving

   Between the chambers are valves. Each valve works like a one-way door. It opens to let blood through and then snaps shut. The "lub-dub" sound of a heartbeat is the sound of valves closing.

   Sidebar: Listen for Yourself
   In 1816, a French doctor named René Laennec rolled a sheet of paper into a tube. He placed one end on a patient's chest and listened. The heartbeat sounded clearer than ever. His idea led to the stethoscope that doctors still use today.

   Feel Your Pulse

   Each time the heart squeezes, it sends a wave of blood through your body. You can feel this wave, called your pulse. Press two fingers gently on the inside of your wrist, below your thumb. Count the beats for fifteen seconds. Then multiply by four to find your beats per minute.

   Keeping Your Heart Strong

   Exercise makes the heart muscle stronger. A strong heart pumps more blood with each beat. As a result, it does not need to beat as often when you are resting.

   Table: Typical Resting Heart Rates
   Newborn baby: 100 to 160 beats a minute
   Child from 6 to 15 years old: 70 to 100 beats a minute
   Adult: 60 to 100 beats a minute
   Trained athlete: 40 to 60 beats a minute

   Glossary
   atria: the two upper chambers of the heart
   oxygen: a gas in the air that the body needs
   pulse: the beat of blood moving through the body, felt at the wrist or neck
   valve: a flap that lets blood flow in only one direction
   ventricles: the two lower chambers of the heart

2. 1.

   A reader wants to know why athletes have low resting heart rates. Which two parts together explain this best?

   • the sidebar and the glossary
   • the diagram caption and the section about valves
   • the section about the four chambers and the caption
   • the section Keeping Your Heart Strong and the table
3. 2.

   According to the diagram caption, what would a red arrow show?

   • blood leaving the lungs as carbon dioxide
   • blood that needs oxygen
   • blood that is rich in oxygen
   • blood passing through a valve
4. 3.

   Use the caption and the section "Two Trips for Every Drop." Which arrows would show blood going from the right side of the heart to the lungs?

   • blue arrows
   • red arrows
   • red arrows, then blue arrows
   • no arrows show this trip
5. 4.

   Why did the author put Laennec's story in a sidebar instead of a main section?

   • It explains the meaning of the word valve.
   • It gives the numbers used in the table.
   • It is an interesting extra, not part of how the heart works.
   • It is the most important fact about the heart.
6. 5.

   Use the table and the section "Keeping Your Heart Strong." Which conclusion is supported?

   • Adults exercise more than children do.
   • An athlete's heart likely pumps more blood with each beat than most adults' hearts.
   • A child's heart is weaker than a newborn's heart.
   • A newborn's heart pumps more blood with each beat than an athlete's.
7. 6.

   Use the glossary and the section about the four chambers. Which chambers squeeze hard to push blood out?

   • the ventricles
   • the atria
   • the valves
   • the lungs
