When your body's tissues are working harder and need more energy, a natural chemical called nitric oxide works with oxygen levels to make sure even the farthest cells from blood vessels still get enough oxygen to keep working properly.
Claim Language
Language Strength
definitive
Uses definitive language (causes, prevents, cures)
The claim uses 'reduces' and 'preserving', which imply direct, causal effects rather than possibilities or associations. These verbs suggest a deterministic outcome: the interaction actively prevents hypoxia and maintains respiration.

The biological lifetime of nitric oxide: implications for the perivascular dynamics of NO and O2.
When tissues work harder and need more oxygen, a gas called nitric oxide helps spread oxygen farther from blood vessels by slowing down how fast cells use oxygen, so more cells get enough to survive.
