    The cold water can also cause heart attack due to vasoconstriction; [4] the heart has to work harder to pump the same volume of blood throughout the body, and for people with heart disease, this additional workload can cause the heart to go into arrest. A person who survives the initial minute of trauma after falling into icy water can survive ...

    The physiology of underwater diving is the physiological adaptations to diving of air-breathing vertebrates that have returned to the ocean from terrestrial lineages. They are a diverse group that include sea snakes, sea turtles, the marine iguana, saltwater crocodiles, penguins, pinnipeds, cetaceans, sea otters, manatees and dugongs.

  4. Bohr effect - Wikipedia

    en.wikipedia.org/wiki/Bohr_effect

    That is, the Bohr effect refers to the shift in the oxygen dissociation curve caused by changes in the concentration of carbon dioxide or the pH of the environment. Since carbon dioxide reacts with water to form carbonic acid, an increase in CO 2 results in a decrease in blood pH, [2] resulting in hemoglobin proteins releasing their load of ...

    Increasing carbon dioxide levels lead to a stronger and stronger breathing reflex, up to the breath-hold breakpoint, at which the person can no longer voluntarily hold their breath. This typically occurs at an arterial partial pressure of carbon dioxide of 55 mm Hg but may differ significantly between people. When submerged into cold water ...

  6. Respiration (physiology) - Wikipedia

    During respiration the C-H bonds are broken by oxidation-reduction reaction and so carbon dioxide and water are also produced. The cellular energy-yielding process is called cellular respiration. Classifications of 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 ...

  8. Rice water is a starchy liquid that results from soaking the grain in water or cooking it in water, Khetarpal explains. Depending on the type of rice, its starch content can range between ~60% to 90%.

    3), and carbon dioxide (CO 2) in order to maintain pH in the blood and duodenum, among other tissues, to support proper metabolic function. [1] Catalyzed by carbonic anhydrase, carbon dioxide (CO 2) reacts with water (H 2 O) to form carbonic acid (H 2 CO 3), which in turn rapidly dissociates to form a bicarbonate ion (HCO −
