Increased plasma sodium, which is called hypernatremia, causes various cells of the body, including those of the brain, to shrink. Shrinkage of the brain cells results in confusion, coma, paralysis of the lung muscles, and death.
Nitrogen gas is not toxic to humans in normal atmospheric concentrations. However, breathing in pure nitrogen gas can lead to asphyxiation because it displaces oxygen in the air, leading to a lack of oxygen in the bloodstream.
When not bonded together in a comnpound chlorine is a pale green/yellow gas that is highly toxic to humans and sodium is a soft silvery metal that quickly tarnishes when cut and reacts vigerously with water to produce hydrogen.
Sodium or SOdium Chloride concentrations that are too high in the body's bloodstream cause water to diffuse (through osmosis) into the blood stream to try and create a balance. Too much water in the bloodstream makes the arteries turgid and increases pressure: thus high blood pressure results and puts pressure on the heart to beat dilute blood around the body until the kidneys can put things back to normal...
uremia
The fastest route for a toxic substance to enter the body is through inhalation, where the substance is absorbed directly into the bloodstream through the lungs. This route allows for rapid delivery of the toxic substance to the bloodstream and major organs.
The kidney is responsible for regulating the concentrations of sodium and chloride in the body by filtering these electrolytes from the blood and reabsorbing or excreting them as needed to maintain balance.

Sodium cyanide (NaCN) is an inorganic toxic salt.
Peak concentrations of stress hormones in the bloodstream occur shortly after encountering a stressful situation. This physiological response is part of the body's fight-or-flight reaction to stress, designed to mobilize energy and resources for immediate action. The levels of stress hormones typically decline as the body's stress response subsides.
When sodium nitrite is added to water, it dissociates into sodium ions (Na+) and nitrite ions (NO2-). The solution may also become slightly acidic due to the hydrolysis of nitrite ions. Sodium nitrite in water can also react with other compounds to form nitric oxide, which can be toxic in high concentrations.
Active transport.
Sodium and chlorone ar toxic and corrosive; sodium chloride is an additive for taste improvement.
