Component
Hydrostatic pressure of head-out water immersion, separate from its temperature
Hydrostatic pressure of head-out water immersion, separate from its temperature. Species, exposure and limitations are retained in each linked claim.

How nutrients influence it
Every nutrient with a recorded effect on this component, credited to the nutrient that acted rather than the chapter that recorded it. Open a nutrient to see the findings and the conditions they were measured under.
Other things that act on it
Enzymes, hormones, genes, and other components with a recorded effect. These are not nutrients, so they do not count toward the arrows above. Each finding names the chapter that recorded it.
How nutrients reach it in more than one step
Chains of two or more recorded steps that end here, grouped by the nutrient they start from. Each step is a separate finding, so a chain is a route a mechanism could take, not proof that it does.

What it does
Every recorded relationship this component is part of, grouped by its role. Plain wording comes first; the technical statement follows.
What it acts on
Immersion at thermoneutral 32 degrees C did not change rectal temperature or metabolic rate but lowered heart rate by 15% and blood pressure by 11 to 12%, lowered plasma renin activity by 46%, cortisol by 34% and aldosterone by 17%, and increased diuresis by 107%.
