Heart and Blood Flow
Trace the path of blood through the heart, lungs and body.
Heart and Blood Flow gives children a drawing of the heart and asks them to name what they see: the atria and ventricles, the aorta, the vena cavae and the pulmonary artery and veins. Level 2 adds color to the thinking, as children decide whether the blood in a chamber or vessel is oxygen-rich or oxygen-poor.
Then the game follows a drop of blood around the loop, asking where it goes next, which chamber receives or pumps it, and how the lungs and body fit in. Further levels cover arteries, veins and capillaries and their jobs. The last level uses simple pulse and heart rate data, including beats counted over a short time.
What children practice
- Name the four chambers and the major vessels of the heart
- Tell oxygen-rich blood from oxygen-poor blood in a diagram
- Trace blood from the body to the heart, lungs and back
- Describe the jobs of arteries, veins and capillaries
- Convert a pulse counted in seconds to beats per minute
- Read a graph of heart rate during rest, walking and running
Levels
- Level 1: Name the heart parts
- Level 2: Oxygen-rich or oxygen-poor
- Level 3: Follow the blood
- Level 4: Arteries, veins, capillaries
- Level 5: Heart rate and pulse
How it works
- Five levels build from naming parts to heart rate and pulse.
- Five right answers and the practice timer open up the next level.
- If your child picks a wrong answer, the game encourages another try.
- Each question can be read aloud, and the explanations point out tricky cases like the pulmonary artery.
Best for: A good fit for grades 5 to 10 when children are learning how the circulatory system works or reviewing it before a test.
Tip for parents: Have your child find their pulse at rest, then after jumping jacks, and count beats for 15 seconds each time. They can compare the numbers and then try the pulse questions in the game.
Questions parents ask
Why are some blood questions tricky?
A few have surprising answers on purpose. The pulmonary artery carries oxygen-poor blood and the pulmonary veins carry oxygen-rich blood. The explanation after each correct answer points out these exceptions to the usual rule.
Does the game cover heart rate?
Level 5 does. Students count beats in a short time and convert to beats per minute, work out beats in a given number of seconds, and read a bar graph comparing pulse while resting, walking and running.
Is this game only about the heart?
No. It also covers blood vessels and the loop to the lungs and body. Level 4 focuses on arteries, veins and capillaries, including which direction blood flows and what each vessel does.
