Arterial blood

Arterial blood is the blood that is pumped out of your heart and sent to the rest of your body. It carries oxygen and nutrients to all of your organs and tissues. Think of it like a hot water pipe that carries hot water around your house; it delivers water where you need it. Arterial blood is really important because all of your organs need oxygen and other things to stay healthy and work properly.
