e. Dead space is the volume of air that is inhaled that does not take part in the gas exchange, because it either remains in the conducting airways or reaches alveoli that are not perfused or poorly perfused. It means that not all the air in each breath is available for the exchange of oxygen and carbon dioxide.
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 ...
FMA. 265130. Anatomical terminology. [ edit on Wikidata] The respiratory tract is the subdivision of the respiratory system involved with the process of conducting air to the alveoli for the purposes of gas exchange in mammals. [1] The respiratory tract is lined with respiratory epithelium as respiratory mucosa. [2]
A normal posteroanterior (PA) chest radiograph of someone without any signs of injury. Dx and Sin stand for "right" and "left" respectively. A chest radiograph, chest X-ray ( CXR ), or chest film is a projection radiograph of the chest used to diagnose conditions affecting the chest, its contents, and nearby structures.
Pulmonary alveolus. A pulmonary alveolus ( pl.: alveoli, from Latin alveolus, "little cavity"), also known as an air sac or air space, is one of millions of hollow, distensible cup-shaped cavities in the lungs where pulmonary gas exchange takes place. [1] Oxygen is exchanged for carbon dioxide at the blood–air barrier between the alveolar air ...
The lungs are the central organs of the respiratory system in humans and some other animals, including tetrapods, some snails and a small number of fish. In mammals and most other vertebrates, two lungs are located near the backbone on either side of the heart. Their function in the respiratory system is to extract oxygen from the air and ...
Breathing. 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 ( inhalation) and out of ( exhalation) the lungs to facilitate gas exchange with the internal environment, mostly ...
The thoracic cavity(or chest cavity) is the chamberof the body of vertebrates that is protected by the thoracic wall(rib cageand associated skin, muscle, and fascia). The central compartment of the thoracic cavity is the mediastinum. There are two openings of the thoracic cavity, a superior thoracic aperture known as the thoracic inletand a ...
