The respiratory system (also respiratory apparatus, ventilatory system) is a biological system consisting of specific organs and structures used for gas exchange in animals and plants. The anatomy and physiology that make this happen varies greatly, depending on the size of the organism, the environment in which it lives and its evolutionary ...
Tidal volume: that volume of air moved into or out of the lungs during quiet breathing (VT indicates a subdivision of the lung; when tidal volume is precisely measured, as in gas exchange calculation, the symbol TV or V T is used.) FRC: Functional residual capacity: the volume in the lungs at the end-expiratory position: RV/TLC%
Real-time magnetic resonance imaging of the human thorax during breathing X-ray video of a female American alligator while breathing. Breathing (spiration [1] or ventilation) is the rhythmical process of moving air into and out of the lungs to facilitate gas exchange with the internal environment, mostly to flush out carbon dioxide and bring in oxygen.
English: The respiratory system consists of the airways, the lungs, and the respiratory muscles that mediate the movement of air into and out of the body. Español : Diagrama esquemático del sistema respiratorio humano , mostrando los pulmones , los alvéolos , y los músculos que permiten al aire entrar y salir del cuerpo.
The process of breathing does not fill the alveoli with atmospheric air during each inhalation (about 350 ml per breath), but the inhaled air is carefully diluted and thoroughly mixed with a large volume of gas (about 2.5 liters in adult humans) known as the functional residual capacity which remains in the lungs after each exhalation, and ...
Lungs can be affected by a number of diseases and disorders. Pulmonology is the medical speciality that deals with respiratory diseases involving the lungs and respiratory system. [86] Cardiothoracic surgery deals with surgery of the lungs including lung volume reduction surgery, lobectomy, pneumectomy and lung transplantation. [87]
The spinal cord reflex responses include the activation of additional respiratory muscles as compensation, gasping response, hypoventilation, and an increase in breathing frequency and volume. The nasopulmonary and nasothoracic reflexes regulate the mechanism of breathing through deepening the inhale.
The Humphrey ADE is a multifunctional breathing system which can be converted into a type A, D or E system depending on the requirements by flipping a lever to change the order of the fresh gas, reservoir and valves. It therefore can be optimised to allow efficient spontaneous or controlled ventilation in both children and adults.
