The circulation system! Please, read and review!

 Dear students, 

Let´s review and underline the info related to the Circulatory system:

Circulation

When blood enters the heart, it´s pumped into the lungs. In the lungs, the red blood cells absorb oxygen. This oxygenated blood is pumped back into the heart. The heart then pumps the oxygenated blood around the body.

The blood vessels are tubes that connect the heart to the rest of the body. There are three types of blood vessels.: arteries, veins and capillaries. Arteries carry blood away from the heart. Veins carry blood back to the heart. Capillaries are tiny blood vessels that connect the smallest arteries to the smallest veins. Capillaries have very thin walls so gases, nutrients and waste products can go through them to the cells.

Let´s create a mindmap:

How are the nutrients and oxygen are transported to the organs and bones?

What´s the function of the heart?

What are the red blood cells responsible for?

What do white blood cells do and platelets?

How many types of blood vessels do we have?

What is the difference between arteries and veins?

Please, underline the process of circulation with the 5 steps.
