It’s another 12 Months of Montessori Series and today I’m going to share with you some simple and easy to prepare lessons and activities for learning the circulatory system of the human body. I mentioned earlier how Mavi was asking me a lot of things about the human heart and the diseases of the heart that causes death in some famous people. Bombarding me with so many questions and that eagerness to learn, we worked on this unit study to:
- Learn about the human heart and how it functions
- What causes heart diseases
- A better understanding of blood vessels: vein and artery
- How to prevent heart diseases
- What’s the role of the blood in the human body
In this unit study, we focused on the three major elements that comprises the circulatory system:
- the human heart
- blood vessels
- human blood
As a bonus, I also added a few pointers on how to have a healthy heart!
The Human Heart
Last month, we learned about the human heart, the different parts and how it functions. You can learn more about it in this post, How to Teach the Anatomy of the Human Heart to Kids.

Blood Vessels
First we plotted the network of blood vessels in our body using our Cardiovascular Information Diagrams sheet as a guide and a printed outline of the human body. We used PlayDoh (red and blue) to represent the vein and artery.
This activity will introduce the child to the basic concept of how blood is distributed in our body. By plotting the veins and arteries, they will understand how the organs in the body receives oxygen and nutrients.

Working diligently to replicate our guide

And he realized that even the head have blood vessels!

We went a little farther by inspecting the network of blood vessels, learning the difference between the veins and arteries and capillaries. Below is a demonstration of the direction of the blood flow in the body through the blood vessels, of how oxygen rich blood enters the artery (except pulmonary arteries) to the capillaries (where oxygen is distributed to the organs) and passes through the vein to enter the human heart.

Here Mavi’s creating an artery, vein and capillary.

He even made his network and labelled the parts.

The Human Blood
This is to demonstrate the composition of blood. 45% red blood cells (red coloured water), 54% plasma (cooking oil) and 1% platelets (bubbles in between).

Care of our Heart
These cards are included in our heart model. It identifies 10 foods that are essential for a healthy heart. Mavi was seriously reading all through the 10 cards and checking if he’s consuming them. Well of course, he eats almost everything in the list except for the broccoli and wine
