Part 2 of 3 The Respiratory and Circulatory Systems 1. The main part of the respiratory system is the lungs. 2. The job of the Respiratory System is to provide oxygen to the body and remove carbon dioxide. 3. Air enters your body through your nose and mouth. It goes down your trachea to your lungs. As you breathe in, your chest gets bigger and your lungs fill with air. 4. We breathe in oxygen and breathe out carbon dioxide. 5. The main parts of the Circulatory System is the heart, arteries, veins, and capillaries. 6. The job of the Circulatory System is to carry blood to and from body cells. 7. The heart is the muscle that pumps blood through your blood vessels to all parts of your body. 8. Your heart is about as big as your fist. 9. The heart is very strong and works all the time, resting only between beats. 10. Veins are the large blood vessels that return the blood to your heart. 11. Blood moves nutrients throughout your body and fights infection. 12. Get plenty of exercise to keep your heart and lungs strong. 13. Proteins build and repair body tissues and supplies energy to the body. Vegetable sources of protein, such as beans, nuts, and whole grains, are excellent choices, and they offer healthy fiber, vitamins and minerals. The best animal protein choices are fish and poultry. ||
