Respiratory inductance plethysmography (RIP) is a method of evaluating pulmonary ventilation by measuring the movement of the chest and abdominal wall. Accurate measurement of pulmonary ventilation or breathing often requires the use of devices such as masks or mouthpieces coupled to the airway opening.
In physiology, respiration is the transport of oxygen from the outside environment to the cells within tissues, and the removal of carbon dioxide in the opposite direction to the environment by a respiratory system. [1]
His colleagues therefore believed that they could easily reproduce Priestley's experiments to verify them or to answer the questions that had puzzled him. [8] Although many of his results puzzled him, Priestley used phlogiston theory to resolve the difficulties. This theory, however, led him to conclude that there were only three types of "air ...
Anaerobic cellular respiration and fermentation generate ATP in very different ways, and the terms should not be treated as synonyms. Cellular respiration (both aerobic and anaerobic) uses highly reduced chemical compounds such as NADH and FADH 2 (for example produced during glycolysis and the citric acid cycle) to establish an electrochemical gradient (often a proton gradient) across a membrane.
The company was founded by Alakh Pandey in 2016 as a YouTube channel aimed at teaching the physics curriculum for the Joint Entrance Examinations (JEE). In 2020, Panday, along with his cofounder Prateek Maheshwari created the Physics Wallah app, which allowed students to access courses related to the National Eligibility cum Entrance Test (NEET ...
Liquid breathing is a form of respiration in which a normally air-breathing organism breathes an oxygen-rich liquid which is capable of CO 2 gas exchange (such as a perfluorocarbon). [ 1 ] The liquid involved requires certain physical properties, such as respiratory gas solubility, density, viscosity, vapor pressure and lipid solubility, which ...
The rate of change gives a direct and reasonably accurate reading for the organism's rate of respiration. As changes in temperature or pressure can also affect the displacement of the manometric fluid, a second respirometer identical to the first except with a dead specimen (or something with the same mass as the specimen in place of the ...
Huff and Puff Apparatus respiration demonstration. The huff and puff apparatus is used in school biology labs to demonstrate that carbon dioxide is a product of respiration. A pupil breathes in and out of the middle tube. The glass tubing is arranged in such a way that one flask bubbles as the pupils breathes in, the other as the pupil breathes ...
