The lungs are the primary organs of the respiratory system in humans and most animals including a few fish, and some snails.
Mammals, reptiles and birds use their different muscles to support and foster breathing.
Layer of gases retained by Earth's gravity that surrounds the planet and forms its planetary atmosphere.
Within the atmosphere, air suitable for use in photosynthesis by terrestrial plants and breathing of terrestrial animals is found only in Earth's troposphere.
Exhalation (or expiration) is the flow of the breath out of an organism.
Compare hypopnea, bradypnea, and hyperventilation.
Hypoventilation (also known as respiratory depression) occurs when ventilation is inadequate (hypo meaning "below") to perform needed respiratory gas exchange.
Hyperventilation occurs when the rate or tidal volume of breathing eliminates more carbon dioxide than the body can produce.
The respiratory rate is the rate at which breathing occurs; it is set and controlled by the respiratory center of the brain.
Subdivision of the respiratory system involved with the process of respiration in mammals.
The diaphragm is also the main muscle of respiration involved in breathing, and is controlled by the sympathetic nervous system.
Enclosure that comprises the ribs, vertebral column and sternum in the thorax of most vertebrates, protects vital organs such as the heart, lungs and great vessels.
The rib cage intrinsically holds the muscles of respiration (diaphragm, intercostal muscles, etc.) that are crucial for active inhalation and forced exhalation, and therefore has a major ventilatory function in the respiratory system.
Long stem-like structure which makes up the lower part of the brainstem.
The medulla contains the cardiac, respiratory, vomiting and vasomotor centers, and therefore deals with the autonomic functions of breathing, heart rate and blood pressure as well as the sleep wake cycle.
Chemical element with the symbol O and atomic number 8.
He noted that candles burned brighter in the gas and that a mouse was more active and lived longer while breathing it.
