This illustration demonstrates the normal kidney physiology, including the Proximal Convoluted Tubule (PCT), Loop of Henle, and Distal Convoluted Tubule (DCT). It also includes illustrations showing where some types of diuretics act, and what they do. Renal physiology (Latin renes, "kidneys") is the study of the physiology of the kidney.
Carbon dioxide absorbs some of the radiation, allowing more radiation that passes through the reference cell to reach the detector than radiation passing through the sample cell. Data is collected on a strip chart recorder. The concentration of carbon dioxide in the sample is quantified by calibrating with a standard gas of known carbon dioxide ...
Capnography is the monitoring of the concentration or partial pressure of carbon dioxide (CO 2) in the respiratory gases.Its main development has been as a monitoring tool for use during anesthesia and intensive care.
The respiratory exchange ratio (RER) is the ratio between the metabolic production of carbon dioxide (CO 2) and the uptake of oxygen (O 2). [3] [4] The ratio is determined by comparing exhaled gases to room air. Measuring this ratio is equal to RQ only at rest or during mild to moderate aerobic exercise without the accumulation of lactate.
Carbon dioxide is often mentioned in the context of its increased influence as a greenhouse gas since the pre-industrial (1750) era. In 2013, the increase in CO 2 was estimated to be responsible for 1.82 W m −2 of the 2.63 W m −2 change in radiative forcing on Earth (about 70%). [48]

Colorimetric capnography is a qualitative measurement method that detects the presence of carbon dioxide (CO2, a relatively acidic gas) in a given gaseous environment. From a medical perspective, the method is usually applied by exposing litmus paper/film to an environment containing a patient's airway gases (i.e. placing it into their breathing circuit/airway circuit), where it will then ...
Carbon dioxide is a gaseous product of the body's metabolism and is normally expelled through the lungs. Carbon dioxide may accumulate in any condition that causes hypoventilation, a reduction of alveolar ventilation (the clearance of air from the small sacs of the lung where gas exchange takes place) as well as resulting from inhalation of CO 2.
