What are the four parts of the heart?

Right Atrium
This is the chamber located at the upper right-hand side of the heart. Its primary function is to receive deoxygenated blood returning from the body through the superior and inferior vena cava. The right atrium then pumps the blood into the right ventricle.

Right Ventricle
Situated below the right atrium, the right ventricle is responsible for receiving deoxygenated blood from the right atrium and pumping it into the pulmonary artery. From there, the blood is sent to the lungs, where it picks up fresh oxygen.

Left Atrium
Positioned on the upper left side of the heart, the left atrium receives oxygen-rich blood from the lungs via the pulmonary veins. It acts as a reservoir for this oxygenated blood before it is pumped into the left ventricle.

Left Ventricle
Found below the left atrium, the left ventricle is the most muscular and powerful chamber of the heart. Its main task is to receive oxygenated blood from the left atrium and forcefully pump it out through the aorta, the body’s largest artery. This ensures that oxygen and nutrients reach all the organs and tissues of the body.

What are some fun facts about the human heart?

  • The average adult heart beats around 100,000 times per day, pumping about 2,000 gallons (7,571 liters) of blood.
  • The heart has its own electrical system that controls its rhythm, known as the sinoatrial (SA) node, often called the “natural pacemaker” of the heart.
  • The heart can continue to beat even if it is separated from the body, as long as it receives a supply of oxygenated blood.
  • Emotions can influence the heart’s rhythm. Love, fear, excitement, and sadness can all impact heart rate and blood pressure.
  • The heart is the first organ to form in a developing embryo.
  • The sound of a heartbeat is the sound of the heart valves opening and closing.
  • The heart is about the size of a fist and weighs around 10 ounces (283 grams).
  • The heart begins beating as early as four weeks after conception, often before the mother even realizes she is pregnant.
  • Contrary to popular belief, the heart is not located on the left side of the chest. It is positioned slightly left but primarily in the center of the chest.

Materials

  • Mason Jar
  • Multiple Balloons
  • Water
  • Food Dye
  • Plastic Straws
  • Duck Tape

Tools

  • Cutting Scissors
  • Casserole Dish or deep dish

Instructions

  1. Mix together the food dye and water in the mason jar
  2. Cut one of the balloons in half and throw away the bottom half
  3. Use remaining half and put over a plastic straw, tape the edge of the balloon to the top of the straw to secure
  4. With another balloon, cut it in half and throw away the bottom half again, stretch the top half over the lid of the mason jar, cut two tiny slits into the stretched balloon, and tape the balloon to the lid of the mason jar to stay
  5. Push the straw from before, along with another one through each slit in the balloon
  6. Push the top of the straw without the balloon downward, using the bending mechanism
  7. Put the mason jar in the casserole dish or deep dish
  8. In order to make the model work, push on the balloon that is stretched on the lid of the mason jar, water will come out of the regular straw. And the balloon covered straw should inflate and deflate and you press repeatedly on the balloon.
