  2. Respiration (physiology) - Wikipedia

    en.wikipedia.org/wiki/Respiration_(physiology)

    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.

  3. Exhalation - Wikipedia

    en.wikipedia.org/wiki/Exhalation

    The main reason for exhalation is to rid the body of carbon dioxide, which is the waste product of gas exchange in humans. Air is brought into the lungs through inhalation. Diffusion in the alveoli allows for the exchange of O 2 into the pulmonary capillaries and the removal of CO 2 and other gases from the pulmonary capillaries to be exhaled ...

  4. Carbon dioxide - Wikipedia

    en.wikipedia.org/wiki/Carbon_dioxide

    Carbon dioxide is the lasing medium in a carbon-dioxide laser, which is one of the earliest type of lasers. Carbon dioxide can be used as a means of controlling the pH of swimming pools, [139] by continuously adding gas to the water, thus keeping the pH from rising. Among the advantages of this is the avoidance of handling (more hazardous) acids.

  5. Cellular respiration - Wikipedia

    en.wikipedia.org/wiki/Cellular_respiration

    From the complete oxidation of one glucose molecule to carbon dioxide and oxidation of all the reduced coenzymes. Although there is a theoretical yield of 38 ATP molecules per glucose during cellular respiration, such conditions are generally not realized because of losses such as the cost of moving pyruvate (from glycolysis), phosphate, and ...

  6. Carbaminohemoglobin - Wikipedia

    en.wikipedia.org/wiki/Carbaminohemoglobin

    Transporting Carbon Dioxide: This process allows for the transport of carbon dioxide from the tissues to the lungs. It is essential for maintaining the balance of gases in the bloodstream and to guarantee the removal of waste carbon dioxide from the body. [17] Buffering Blood pH: The binding of carbon dioxide to hemoglobin helps buffer blood pH.

  7. Gaseous signaling molecules - Wikipedia

    en.wikipedia.org/wiki/Gaseous_signaling_molecules

    Gaseous signaling molecules are gaseous molecules that are either synthesized internally (endogenously) in the organism, tissue or cell or are received by the organism, tissue or cell from outside (say, from the atmosphere or hydrosphere, as in the case of oxygen) and that are used to transmit chemical signals which induce certain physiological or biochemical changes in the organism, tissue or ...

  9. Heart - Wikipedia

    en.wikipedia.org/wiki/Heart

    Chemoreceptors present in the carotid body or adjacent to the aorta in an aortic body respond to the blood's oxygen, carbon dioxide levels. Low oxygen or high carbon dioxide will stimulate firing of the receptors. [53] Exercise and fitness levels, age, body temperature, basal metabolic rate, and even a person's emotional state can all affect ...
