The respiratory system by sarah

  2. 2. The respiratory system<br />Oxygen is taken into the body through the airways, absorbed into the lungs, then transported through the body in the blood. The lungs also give out carbon dioxide into the atmosphere.   Humans and land animals with backbones have similar respiratory systems. This system includes passages that connect the nose and mouth to the lungs. <br />Your respiratory system, but it is essential for life. Every once in a while a cough, sneeze, or hiccup will remind you about this body system. A cough is the way your system clears the airway. A sneeze is caused by an irritation in the upper airway. A hiccup is a spasm of the diagram.<br />
  3. 3. The lungs <br /> lungs are in your chest, and they are so large that they take up most of the space in there. You have two lungs, but they aren't the same size. Instead, the lung on the left side of your body is a bit smaller than the lung on the right. This extra space on the left leaves room for your heart.<br />Your lungs are protected by your rib cage, which is made up of 12 sets of ribs. These ribs are connected to your spine in your back and go around your lungs to keep them safe<br />Inside your lungs there is the Alveoli, Bronchus, Bronchioles.<br />
  4. 4. Nose and Mouth<br />Your nose and mouth are there to take in air and take out air. So you breath in and out with your nose and mouth.<br />
  5. 5. Diaphragm <br />The diaphragm is the main breathing muscle, it contracts when inspiring, the muscle releases when expiring.<br />The diaphragm is a dome-shaped muscle located below your lungs.The diaphragm is the main muscle used for breathing.<br />Beneath your diaphragm are abdominal muscles. They help you breathe out when you're breathing fast <br />Diaphragm<br />
  6. 6. Trachea <br />The trachea (or your wind pipe) is wider, stronger, and rough and bumpy in structure. The trachea is to be always open, to allow air passage to and from the lungs.<br />
