| Provision of the Respiratory System | Provides oxygen to the blood and removes carbon dioxide from the body |
| What is essential to survival in respiration | The continual exchange of gases |
| Oxygen moves from the lungs into the blood, and carbon dioxide moves from the blood into the lungs | External Respiration |
| Oxygen moves from the blood into the cells, and carbon dioxide moves from the cells | Internal Respiration |
| Consistency of the Respiratory System | Lungs, trachea, and diaphragm |
| A muscle that separates the chest from the abdominal cavity | Diaphragm |
| Inhaling | the pressure inside the lungs is lower than the pressure outside the body, so air flows into the lungs to equalize |
| Exhaling | the pressure inside the lungs is higher than the pressure outside the body, so air flows out to equalize it |
| The Windpipe | Trachea |
| The main airway that reach into each lung | Bronchi |
| A network of tubes that branch from the Bronchi | Bronchioles |
| Microscopic thin-walled air sacs covered with capillaries(gas exchange takes place) at the end of each bronchiole | Alveoli |
| Where the air enters | Nose and Mouth |
| Throat | Pharyx |
| Voice-Box(adam's apple) | Larynx |
| Small flap of tissue that covers the trachea when swallowing | Epiglottis |
| How to maintain good respiratory health | Don't smoke, exercise, wash hands, limit exposure to pollutants |
| Inflammation of the sinus cavity | Sinusitis |
| Inflammation of the bronchi | Bronchitis |
| Inflammation of the lungs | Pneumonia |
| An involuntary contraction of smooth airway muscles lead to chest tightness and breathing difficulty | Asthma |
| A bacterial infection of the lungs | Tuberculosis |
| Contents of Tuberculosis | Immune system surrounds infected area and isolates it , may not show symptoms for years |
| A disease that destroys the walls of the alveoli | Emphysema |
