What's the difference between alveolus and oxygen?

Alveolus


Definition:

  • (n.) A cell in a honeycomb.
  • (n.) A small cavity in a coral, shell, or fossil

  • (15) The method involves the delivery of fresh gas to the respiratory tree during expiration, thereby flushing out the anatomic deadspace and ensuring that the gas initially delivered to the alveolus with the succeeding inspiration is able to participate in gas exchange.
  • (16) This rare malignancy occurred in the maxillary alveolus, appearing as an epulis.
  • (17) Surgical repair of the lip is done within the first 2 months of life, by the time the nose, alveolus and projecting prolabium are adequately reformed.
  • (18) These data are consistent with exogenous cholesterol being rapidly esterified in the alveolus, and the ester then being cleared by the macrophages.
  • (19) Because macrophages and epithelial cells are in close physical contact within the alveolus, we measured the eicosanoids produced by combined cultures of these cells.
  • (20) The aim of this study was to compare permanent tooth length development in children with complete unilateral clefts of the lip, alveolus, and palate (UCLP) with that of tooth length development in a normal reference population.

Oxygen


Definition:

  • (n.) A colorless, tasteless, odorless, gaseous element occurring in the free state in the atmosphere, of which it forms about 23 per cent by weight and about 21 per cent by volume, being slightly heavier than nitrogen. Symbol O. Atomic weight 15.96.
  • (n.) Chlorine used in bleaching.

Example Sentences:

  • (1) Steady-state values of cell, glucose, and cellulase concentration oxygen tension, and outlet gas oxygen partial pressure were recorded.
  • (2) It is concluded that amlodipine reduces myocardial ischemic injury by mechanism(s) that may involve a reduction in myocardial oxygen demand as well as by positively influencing transmembrane Ca2+ fluxes during ischemia and reperfusion.

  • (6) These membrane perturbation effects not observed with bleomycin-iron in the presence of a hydroxyl radical scavenger, dimethyl thiourea, or a chelating agent, desferrioxamine, were correlated with the ability of the complex to generate highly reactive oxygen species.
  • (7) Microelectrodes were used to measure the oxygen tension (PO2) profile within individual spheroids at different stages of growth.
  • (8) However, time in greater than 21% oxygen was significantly longer in infants less than 1000 g (median 30 days, 8.5 days in patients greater than 1000 g, p less than 0.01).
