the system that circulates blood and lymph through the body,
consisting of the heart, blood vessels, blood, lymph, and the lymphatic
vessels and glands.
The circulatory system carries blood to every part of your body. Your heart beats to pump blood all throughout your body. Blood is very important because it keeps your body warm and helps it to move. When the heart pulls in and pumps out blood, the arteries transport it to different locations in your body. The artery is basically a tube that transports the blood.
