The Circulatory System
Grade 6 · Science · Body Systems · Oklahoma, USA
Lesson Summary
The circulatory system moves blood throughout the body, delivering oxygen and nutrients and removing waste.
Explanation
The circulatory system is made up of the heart, blood vessels, and blood. The heart pumps blood through two loops: one sends blood to the lungs to pick up oxygen, and the other sends oxygen-rich blood to the rest of the body. Arteries carry blood away from the heart, veins carry blood back to the heart, and tiny capillaries connect them and allow nutrients and oxygen to pass into cells. Blood also carries waste products like carbon dioxide back to the lungs to be exhaled.
