3ºC Circulatory system. Manipulative activity.

Why is the circulatory system important? Is it related to the respiratory system? and to the digestive system?

Alter reflecting on this individually and in groups, we put all our ideas together and concluded that the circulatory system is essential because:

"The heart pumps blood around the body giving our body nutrients and oxygen. Blood also carries carbon dioxide that leaves the body through the respiratory system"

"There are two types of blood vessels through which the blood moves: veins (they carry blood full of carbon dioxide, CO2) an arteries (they carry blood full of oxygen, O2)."

Once we understood it, in groups we:

1. Drew our body silhouette. 
2. Represented the heart using plasticine.
3. Represented veins and arteries using blue and red wool.

Here are some pictures!
