Respiratory and Circulatory Study Notes
Respiratory System: What is the function of the respiratory system: The function is to bring oxygen in and carbon dioxide out of the body. The oxygen is carried through out the body in the blood stream. What are the main parts found in the respiratory system? 1. Lungs 2. Trachea 3. Nose 4. Bronchioles 5. Diaphragm 6. Bronchi 7. Epiglottis 8. Mouth 9. Alveoli 10. Pharynx 11. Larynx 12. Capillaries (Cross over from the Circulatory System – this is how both systems are connected) 13. Nasal Cavity You will need to be able to label the parts of the body. How does the body bring in oxygen and takes out carbon dioxide? When you breath in through your nose. The air travels down your trachea into your lungs. Where it travels into the bronchi which travels down the bronchioles into the alveoli’s. There the capillaries exchange oxygen for carbon dioxide. *** The process of inhaling and exhaling. To inhale, your diaphragm must contract to create space in your chest for air to fill up. To exhale your diaphragm must relax to push out the carbon dioxide. Circulatory System: What is the function of the circulatory system: To pump blood through out the body that contains oxygen and nutrients to support your body’s needs. What are the main parts found in the circulatory system? 1. Heart 2. Vessels – Artery (from the heart & Veins (to the heart) 3. Blood (Red, White, Plasma, Platelets) You will need to label the heart. You will also need to show the blood flow. Final Question:
How are these two system connected to each other?
