Circulatory system cartoon biology 2
Storyboard Text
- What is the circulatory system?The circulatory system transports oxygen, nutrients and hormones to your body's cells to use for energy, growth and repair. Your circulatory system also removes carbon dioxide and other wastes your cells do not need.
- Parts of the irculatory system:-Blood: made up of cells and plasma-The heart: a muscular organ that pumps blood to all parts of your body-Blood vessels: a network of arteries, capillaries and veins to carry blood pumped by your heart
- How the circulatory system works?Blood that is low in oxygen collects in your heart's right atrium, one of the heart’s 4 chambers. It moves into the right ventricle, which pumps this blood to your lungs where your red blood cells pick up oxygen and get rid of carbon dioxide. You exhale the carbon dioxide. The oxygen-rich blood returns to your heart's left atrium, then into your left ventricle. The left ventricle pumps oxygen-rich blood through your aorta, into your arteries, then to all parts of your body. Along the way, the blood gathers food nutrients from your small intestine. As it enters the capillaries, your blood makes close contact with tissues and cells. It delivers oxygen and nutrients and removes carbon dioxide and wastes. Now low in oxygen, the blood travels through the veins to return to your heart's right atrium, where the circuit starts all over again.

- Then we talked about the parts of the circular system.
- Finally we explained how the circulatory system works.
