| Pulmonary respiration | ventilation |
| Cellualar respiration | relates to O2 utilization and CO2 production by the tissues |
| Nasal passages | warm, humiditfy and filter air |
| Trachea/Windpipe | contain cilia that move in a wavelike fashion |
| Bronchi | large passageways |
| Bronchiole | smaller passageways |
| Alveoli | 300 million air sacs where gaseous exchange actually takes place |
| Diaphragm | a strong sheet of muscle at the bottom of the chest cavity which helps us to breath |
| Bronchitis | inflammation of the bronchial tubes |
| Asthma | the air passages swell and narrow the airway. (Allergic reaction) |
| Emphysema | the alveoli enlarge and lose elasticity, making the exchange of gases more difficult |
| Lung Cancer | abnormal cells multiply and divide eventually destroying lung tissue |
| Respiratory System | provides a means of gas exchange between the environment and the body |
| Ventilation | refers to the mechanical process of moving air into and out of lungs |
| Diffusion | random movement of molecules from an area of high concentration to an area of lower concentration |
| Inspiration | Diaphragm pushes downward, lowering intrapulmonary pressure |
| Expiration | Diaphragm relaxes, raising intrapulmonary pressure |
| Pulmonary Ventilation | The amount of air moved in or out of the lungs per minute |
| Vidal Capacity (VC) | maximum amount of air that can be expired following a maximum inspiration |
| Residual Volume(RV) | Air remaining in the lungs after a maximum expiration |
| Circulatory System | A group of organs which carry food and oxygen to and remove waste from every cell in the body |
| Hemoglobin | the oxygen-carrying protein in blood |
| White blood cells | protect the body against infection and fight infection when it comes |
| Arteries | the blood vessels that carry blood away from the heart |
| Capillaries | small vessels that carry blood between arterioles and small vessels called venules |
| Veins | blood vessels that return blood to the heart |
| Platelets | cells that prevent the body's loss of blood |
| Plasma | the fluid in which other parts of the blood are suspended |
| Heart | the pump that makes the cardiovascular system work |
| Blood pressure | is a measure of the amount of force that the blood places on the walls of blood vessels, particularly large arteries, as it is pumped through the body. |
