The Circulatory System flashcards are a set of study tools designed to help students learn about the human circulatory system. This system has been studied for centuries, with scientists and doctors making important discoveries about how blood flows through the body.
Understanding the Circulatory System is important because it helps us learn how our bodies work and how to keep them healthy. By studying these flashcards, students can learn about the heart, blood vessels, and the role of blood in transporting oxygen and nutrients throughout the body.

quick facts
- The circulatory system is made up of the heart, blood vessels, and blood.
- Each day, the heart pumps about 2,000 gallons of blood through the body.
- Blood vessels in the body can stretch out to be over 60,000 miles long.
- The circulatory system helps deliver oxygen and nutrients to all the cells in the body.
- Heartbeats are controlled by electrical signals that tell the heart when to contract and relax.
