| respiratory system | the group of organs that provides living things with oxygen from outside the body and disposes of waste products such as carbon dioxide
🗑
|
||||
| respiration | all of the processes involved in bringing oxygen into the body, making it available to each cell, and eliminating carbon dioxide as waste
🗑
|
||||
| inspiration | the action of drawing oxygen-rich air into the lungs
🗑
|
||||
| expiration | the action of releasing waste air from the lungs
🗑
|
||||
| gas exchange | the transfer of oxygen from the inhaled air into the blood, and of carbon dioxide from the blood into the lungs; it is the primary function of the lungs
🗑
|
||||
| ventilation | the process of drawing or pumping, and oxygen-containing medium over a respiratory surface
🗑
|
||||
| diffusion gradient | describes the relationship in which a dissolved substance moves from a region of high concentration to a region of low concentration
🗑
|
||||
| diaphragm | a sheet of muscle that separates the thoracic cavity from the abdominal cavity
🗑
|
||||
| Spirograph | a graph representing the amount (volume) and speed (rate of flow) of air that is inhaled and exhaled, as measuring by a spirometer
🗑
|
||||
| tidal volume | the volume of air inhaled and exhaled during normal breathing
🗑
|
||||
| inspiratory reserve volume | the volume of air that can be taken into the lungs beyond the regular tidal inhalation
🗑
|
||||
| expiratory reserve volume | the volume of air that can be expelled from the lungs beyond the regular tidal exhalation
🗑
|
||||
| vital capacity | the volume of air that can be exhaled from the lungs during a single breath
🗑
|
||||
| residual volume | the volume of air that remains in the lungs after a complete exhalation
🗑
|
||||
| pharynx | the passageway just behind the mouth that connects the mouth and nasal cavity to the larynx and esophagus
🗑
|
||||
| trachea | the tube that carries air from the nasal passages or mouth to the bronchi and then to the lungs; also known as the windpipe
🗑
|
||||
| glottis | the opening of the trachea through which air enter the larynx
🗑
|
||||
| larynx | the structure between the glottis and the trachea that contains the vocal cords
🗑
|
||||
| bronchus | the passageway that branches from the trachea to the lungs
🗑
|
||||
| bronchiole | the passageway that branches from each bronchus inside the lung into increasingly smaller, thin-walled tubes
🗑
|
||||
| alveolus | a tiny sac, with a wall that is one cell thick, found at the end of a bronchiole; respiratory gases are exchanged in this sac
🗑
|
||||
| hemoglobin | an iron-containing protein found in red blood cells, which binds to and transports oxygen from the lungs to the rest of the body
🗑
