WebReactive hyperemia results from oxygen starvation caused by an occluded blood vessel such as when you sit on your foot funny, and it falls asleep. Then you get up and it feels like someone is sticking a thousand pins in it. False. Reactive hyperemia is the increase in blood flow to a tissue or organ that occurs following a period of reduced ... Superoxide and hydroperoxyl (HO2) are often discussed interchangeably, although superoxide predominates at physiological pHs. Both superoxide and hydroperoxyl are classified as reactive oxygen species. It is generated by the immune system to kill invading microorganisms. In phagocytes, superoxide is produced in large quantities by the enzyme NADPH oxidase for use in oxygen-dependent killing mechanisms of invading pathogens. Mutations in the gene coding for t…
