How does blood travel around our body ?

Our blood travels through our whole body in less than a minute, thousands of times a day. It travels through tubes called blood vessels. There are three main kinds of blood vessels.

oxygen.

It goes into our largest arteries. These branch into the smaller arteries, which branch into even smaller ones. The blood flows from the smallest arteries into our
capillaries.

Capillaries are bridges between our arteries and our veins. They are the tiniest blood vessels, so small that you cannot see them without a microscope.

Blood travels from the capillaries into tiny veins. These lead
