Circulatory System Worksheets for Kids

We’ve been learning about the human body and we’re slowly making our way through all of the body systems with my science worksheets. My kids are always asking about their bodies so these Circulatory System Worksheets for Kids are going to come in handy when we’re ready to jump into our biology unit.

See the rest of my Human Body Worksheets here.

There are many activities you can do and discuss your heart rate while at rest and then after exercise, they’re some wonderful books to illustrate what you’re discussing as well. My favorite is creating play dough models of organs so you can test what your child remembers.

I also like to discuss what’s in the blood but I’ll save that for our immune system discussion for now. While many smaller arteries and veins branch off, I just focused on the larger ones here.

Fun Human Body Facts

Did you know your body is full of amazing surprises? Learning about the human body can be so much fun with these fascinating facts. From your bones to your brain, there’s always something cool to discover!

• Taller in the Morning – When you wake up, you’re a little taller because the soft disks between your spine’s bones compress during the day!
• Hard Brain Work – Your brain sends and receives millions of signals every second to keep your body moving, thinking, and feeling.
• The New You – Your body gets rid of about 40,000 skin cells every minute, creating space for new ones to grow.

Recommended Human Body Books

Extend the activity and explore these amazing, colorful human body books to get a better sense of how the entire body works together.

Always have reference books on hand to help answer your child’s questions. You don’t have to know everything, but you can look up the answers together.

How does blood travel through the body?

The heart is the main organ in the circulatory system. It has an important job to play and that’s to pump blood throughout our body. All of the arteries are in red because they carry blood away from the heart and it has been replenished with oxygen. The blue veins are all coming towards the heart because they are low in oxygen and this is what I tell my kids when we talk about the circulatory system.

The heart also looks like a hollow organ, but it has four chambers.

The right side receives blood that is low in oxygen from the body, it goes through the right atrium to the right ventricle then to the lungs to get oxygen. It then goes through the left atrium to the left ventricle and out through the aorta to the rest of the body.

When the blood leaves the heart, it is at its highest pressure to ensure that it can travel to the rest of the body.

How do you keep your heart healthy?

To keep our heart healthy, we have to get a lot of exercise and eat healthy food that is low in fats. The arteries can start to build up from the fatty foods we eat, which can lead to blockages and heart attacks.

Exercise keeps our heart healthy and strong so that it can get blood to the rest of our body. Eating healthy food makes sure the arteries do not get blocked off.

Recommended Human Body Activity Kits

These activity kits give your kids an engaging way to explore how our bodies work! From coloring organs to matching muscle groups, these kits provide hands-on learning experiences that make science exciting. They’re a great way to encourage curiosity while keeping activities fun and interactive!

Circulatory System Printable Supplies

• Printer (I have this one)
• Paper
• Pencil
• Crayons
• Glue
• Scissors

I have the HP printer 8710 but it’s not available anymore. It’s been running well for years now. Look for another HP Instant Ink-ready printer so that you can use their program to send you ink cartridges whenever your printer gets low on ink.

What’s included in the circulatory system activity?

Circulatory System Illustration

This engaging illustration helps kids visually explore the circulatory system, with labeled parts like the heart, veins, and arteries. It’s a fun and educational way to help them learn how blood flows through the body, while developing an understanding of how everything works together!

Circulatory System Cut and Paste Activity

In this interactive activity, children get to match the different parts of the circulatory system, from the heart to the veins and arteries, and place them in the correct spots. It’s a great hands-on experience that helps with learning anatomy and improves fine motor skills, too.

Color In the Circulatory System

Coloring is always a favorite activity, and with this, kids get to bring the heart, blood vessels, and pathways to life. It’s an exciting way to teach them about the body’s functions while letting them explore their creativity. Watch as they enjoy coloring in each detail!
