Spring 2 - The Circulatory System
This half term we are learning all about the circulatory system and how blood travels around our body.
Deoxygenated blood travels into the right atrium of our heart, then through the right ventricle. It leaves the heart through the pulmonic valve and pulmonary artery to the lungs. In the lungs the blood cells collect oxygen and travel back to the heart. The oxygenated blood re-enters the heart into the left atrium then travels to the left ventricle before leaving via the aortic valve. From the aorta the oxygenated blood travels around the body releasing oxygen and collecting carbon dioxide. The deoxygenated blood then travels back to the heart and the system starts again.
The Circulatory System
Brilliant Blood! This week in science we looked at what is in our blood - we now know that our blood is made up of red blood cells; white blood cells; platelets and plasma - which also has minerals in.
This lesson was tiring! We looked at our heat rate and why it increases and decreases. We did several different exercises and measured our pulse for each one, then measured our recovery time.
