  1. Circulatory System

  2. GOAL of The Day Understand how the lungs and the heart work together to transport oxygen rich blood to cells

  3. Components of Blood • About 55% of blood is a liquid called plasma. • Contains proteins, minerals, and other substances. • Red blood cells carry oxygen from the lungs to the cells. • White blood cells fight infection. • Platelets are important for clotting blood.

  4. Flow of Blood through the heart

  5. Blood that is low in oxygen flows from veins into the right atrium

  6. 2. The right atrium sends this blood to the right ventricle

  7. “LUBB” • When the atrium contracts and pushes blood into the ventricle, the closing of the valve produces this sounds

  8. “DUBB” • When the ventricle pushes blood into the arteries, the closing of the valve produces this sounds

  9. 3. The right ventricle sends the blood to the two lungs so that it can be enriched with oxygen

  10. 4. The oxygen-rich blood moves back from the lungs to the heart and enters the left atrium

  11. 5. The left atrium sends this blood to the left ventricle 5

  12. 6. The left ventricle sends oxygen-rich blood to the whole body through the arteries
