What is the Circulatory System?
The Circulatory System is our body’s delivery system. Our body cannot function as it cannot get the nutrients and energy needed to carry out daily activities without it.
It transports oxygen, food and water to all parts of our body. It is made up of the heart, blood vessels and blood.
Our Circulatory system consists of:
- Heart – a muscle that pumps blood all over the body
- Blood vessels (arteries, veins and capillaries) – Transport oxygen-rich blood away from the heart to the rest of the body (arteries) and carry blood to the heart from the rest of the body (veins )
- Blood – is made up of many cells like red and white blood cells, plasma and platelets and carries nutrients and oxygen.
Some fun facts about our Circulatory System
- Do you know why our blood is red? That is because of the red blood cells (haemoglobin) found in the blood gives it its red colour!
- Our blood vessels are very very long! If we were to lay out your entire blood vessels from end to end, it can go around the world twice!
- There are about 5 million red blood cells in a single drop of blood!
Explore, Explain and Extend™ Approach
Our Explore, Explain and Extend™ Approach (Our E3 Approach) is specially designed to inspire higher order thinking. These make the learning of Science fun and realistic, as well as nurture the passion for learning beyond the school syllabus.
We offer Primary Science Tuition which will cover the MOE syllabus, specially designed by our MOE-trained teachers. This programme focuses on helping the students to understand their school teaching better and prepare for school examinations.
