Alveoli (alveolus)
|
gas exchange structure within lungs; tiny air pocket with walls made of a membrane one cell thick, allowing for respiratory gas exchange.
|
|
Bronchiole
|
the passageway that branches from the bronchi into the separate lobes of the lungs; divides into smaller and smaller passageways that carry air into all portions of the lungs.
|
|
Bronchus (bronchi)
|
the passageway that branches from the trachea into the lungs, with one bronchus carrying air into each lung.
|
|
Diaphragm
|
a muscle layer that separates the region of the lungs (thoracic cavity) from the region of the stomach and liver (abdominal cavity) contraction increases the volume of the thoracic cavity.
|
|
Epiglottis
|
flap of cartilage located over the entrance to the trachea, it closes off the trachea during swallowing.
|
|
Glottis
|
the opening of the trachea through which air enters the larynx.
|
|
Larynx
|
a structure within the upper respiratory tract that contains the vocal cords; also known as voice box.
|
|
Nasal passages
|
passage from the nostrils to the back of the throat through which air enters the body; warms, moistens, and cleans; lined with ciliated cells and mucus-secreting cells.
|
|
Nostril
|
Either of two external openings of the nasal cavity in vertebrates that admit air to the lungs and smells to the olfactory nerves.
|
|
Pharynx
|
structure located just behind the mouth that connects mouth and nasal cavity to the larynx and esophagus; serves purpose as passageway for air into respiratory system and for food and water into digestive system.
|
|
Pleural membrane
|
double-layered membrane that encloses the lungs; also referred to as pleura.
|
|
Thoracic cavity
|
chest cavity: the cavity in the vertebrate body enclosed by the ribs between the diaphragm and the neck and containing the lungs and heart.
|
|
Trachea
|
A tube-like portion of the breathing or "respiratory" tract that connects the "voice box" (larynx) with the bronchial parts of the lungs.
|
|
Spirograph
|
graph representing the amount of air that moves into and out of the lungs.
|
|
Tidal volume
|
volume of air is inhaled and exhaled in a normal breathing movement when the body is at rest.
|
|
Inspiratory reserve volume
|
the maximal amount of gas that can be inhaled from the end-inspiratory position.
|
|
Expiratory reserve volume
|
the maximal amount of gas that can be exhaled from the resting end-expiratory level. Abbreviated ERV.
|
|
Vital Capacity
|
is the maximum amount of air a person can expel from the lungs after a maximum inspiration
|
|
Residual volume
|
the amount of gas remaining in the lung at the end of a maximal exhalation.
|
|
External Respiration
|
the bodily process of inhalation and exhalation; the process of taking in oxygen from inhaled air and releasing carbon dioxide by exhalation
|
|
Internal Respiration
|
the metabolic processes whereby certain organisms obtain energy from organic molecules; processes that take place in the cells and tissues during which energy is released and carbon dioxide is produced and absorbed by the blood to be transported to the lungs.
