Respiratory System
- 2. Like all living things, we need oxygen to live. Our body gets oxygen when you breathe.
- 3. PARTS OF THE RESPIRATORY SYSTEM NOSE LUNGS TRACHEA DIAPHRAGM
- 4. The trachea is the main pipe, that goes from the nose and mouth to your lungs. It is found in the neck . The air enters through the nose, then the trachea leads it into the chest to the lungs. The trachea is divided into 2 main tubes, one leading to each lung. TRACHEA
- 5. The lungs are the place where the exchange of oxygen and carbon dioxide takes place. The smallest branches of your air pipes connect to air sacs. Inside, there are capillaries. When you breathe in, air filled with oxygen collects in the air sacs. Carbon dioxide passes back through the capillary walls into the air sacs. When you breathe out, carbon dioxide travels and goes out. The oxygen passes through the very tiny walls of the capillaries into your blood.
- 6. Involuntary muscle that works to make space in your chest to let the air you breathe in. It is a smooth muscle stretched across the bottom of your lungs When it contracts, it gets flatter and pulls the lungs down. When you breathe out, the muscles relax and the lungs shrink. DIAPHRAGM
- 7. 3. How does the air enter to our body? 5. Why is the diaphragm important? The air enters to our body through the nose or the mouth, then it goes to trachea and reaches the lungs. Because it makes space in your chest to let the air you breathe in. LET’S REMEMBER! 1. Which are the main organs of the Respiratory System? The nose and mouth, the trachea, the lungs and the diaphragm. 2. How many lungs do we have ? We have two lungs. 4. Where does the exchange of oxygen and carbon dioxide occur? In the trachea. In the lungs. In the diaphragm.
- 8. TRACHEA CAN YOU NAME THEM? DIAPHRAGM NOSE ALVEOLI LUNGS
Editor's Notes
- Let´s see if you remember some of our lesson. Get ready! Which are the main organs of the Respiratory System? They are the nose and mouth, the trachea, the lungs and the diaphragm 2. How many lungs do we have? We have two lungs. 3. How does the air enter to our body? It enters to our body through the nose or the mouth. Then it goes to the trachea and reaches the lungs. 4. Where does the exchange of oxygen and carbon dioxide occur? In the trachea? In the lungs? Or in the diaphragm? Of course in the lungs! 5.-Why is the diaphragm important? Because it makes space in your chest to let the air you breathe in. 4. How does the air enter to our body? That’s right, the air enters to our body through the nose, then it goes to the trachea and reaches the lungs. 5. Why is the diaphragm important? Because it makes space in your chest to let the air you breathe in. Now, identify each one of the following organs. The first is….. Correct the stomach. Next picture….. Yes, the lungs. Now this organ is …… very good the large intestine, and the last picture is ….. The trachea.
