| One of two passages that lead to the pharynx. In this one air does not get as filtered. | Oral Cavity |
| One of two passages that lead to the pharynx. In this one air gets filtered, moistened and warmed. | Nasal Cavity |
| Microscopic hair like structures that help filter the air that enters our bodies. | Cilia |
| The area at the back of the throat that connects the nasal and oral cavities to the larynx and trachea. | Pharynx |
| The flap that covers the opening into the trachea when we swallow. | Epiglottis |
| This is called the voice box and it contains the vocal cords. It will grow larger for boys during puberty. | Larynx |
| This is also called the wind pipe. It carries air to the Bronchi. It is held open with cartilage rings so air passes easily through it. | Trachea |
| The tubes that split off from the trachea and enter the lungs. These also carry air to the Bronchioles. | Bronchi |
| The smallest air carrying tubes in the lungs. These carry air to the alveoli. | Bronchioles |
| The farthest point in which air travels in the lungs. It is in here that the blood/gas exchange happens and oxygen will diffuse into the blood stream. | Alveoli |
| These are the smallest of the blood vessel. They are found throughout the body. They are responsible for picking up and delivering oxygen and food to the cells. | Capillaries |
| The organs of the body that contain the alveoli, bronchioles and bronchi. These organs are filled with air due to the movements of the diaphragm. | Lungs |
| This is the large muscle of the respiratory system. It's movements create space in the chest cavity for air to fill up. | Diaphragm |
| The process of the body to take in air, remove the oxygen, transport it to the cells, use the oxygen to release energy from food and remove the waste gas carbon dioxide from the body. | Ventilation and Respiration (Getting and Using) |
| When matter moves from a high concentration to a low concentration typically through a semi-permeable membrane | Diffusion |
| This takes place in the alveoli. It is when gases diffuse from the lungs to the blood and vice versa. | Blood/Gas Exchange |
| These are the smallest of the blood vessel. They are found throughout the body. They are responsible for picking up and delivering waste gas, carbon dioxide, to the lungs to be exhaled. | Capillaries |
| What is cellular respiration? | Cellular respiration is the biological process of cells using oxygen to release energy from food. |
| Name 3 helpful reasons for breathing in through your nose. | Air is: 1.filtered by hair and cilia 2. warmed by capillaries 3. moistened by mucus |
