Constriction of blood vessels and heart rate > maintain blood pressure. Good blood pressure = good nutrient delivery. Water balance regulated by three hormones: antidiuretic hormone (adh, angiotensin ii, aldosterone. Solvent: makes up blood, environment for chem reactions.

Deficiency symptoms emerge more rapidly than any other nutrient. Deficiency in water > deficiency in electrolytes. Dehydration = reduced blood volume, impaired nutrient delivery, waste removal. Early symptoms: thirst, headaches, fatigue, appetite loss, dry eyes/mouth, dark urine. Late symptoms: nausea, lack concentration, confusion, disorientation, collapse. Hyponatremia: too much water, not enough sodium in body; drop sodium concentration: water moves into tissues > swelling, disorientation, convulsions, nausea, muscle cramps, slurred speech, confusion.
