The iron reacts with oxygen, giving blood its red color.Immersion in water alters the cardio-endocrine-renal axis as there is an immediate translocation of blood to the heart and a slower autotransfusion of fluid from the cells to the vascular compartment. Both of these changes result in an increase in stroke volume and cardiac output.Not only is blood mostly water, but the watery portion of blood, the plasma, has a concentration of salt and other ions that is remarkably similar to sea water.hand-washing, or a post-carnage Shower of Angst.

That's the salinity, or the weight in grams of salt dissolved in 1,000 grams (35.27 ounces) of water, of human blood [source: Ocean Health].
