Identify and name the parts of the human circulatory system, and describe the functions of the heart, blood vessels and blood. Understanding the circulatory system in KS2 works to further develop the basis of scientific knowledge children gathered in KS1.
The circulatory system consists of: a system of tubes (arteries, capillaries and veins) a pump (the heart) valves to ensure a one-way flow of blood. Arteries and veins. You have about 5.5 litres...
They let blood flow from the atria to the ventricles. The other two are called the aortic (say: ay-OR-tik) valve and pulmonary (say: PUL-muh-ner-ee) valve, and they're in charge of controlling the flow as the blood leaves the heart. These valves all work to keep the blood flowing forward.
