Document Summary
Water is the most essential nutrient in the body. Accordingly, symptoms of deficiency (thirst) are evidenced rela3vely quickly. Water is a solvent that provides a medium in which molecules can collide and react. Also, the majority of our blood is composed of water, and the volume of water in our blood helps determine blood pressure. Certain hormones (adh, aldosterone, angiotensin ii) are essen3al to this regula3on. Distribu3on of water in the body approximately 60% of body weight = water: found both inside (2/3) and outside (1/3) of cells water content of intra/extracell. spaces depends on. Solute concentrations (proteins, sodium, potassium etc. : water moves by osmosis to achieve proper solute concentra3ons. Blood pressure, which forces water out of blood. We do not store water in the body, so each day water losses approximately equal water gains. Adequate water levels maintain blood volume, which helps maintain blood pressure. Theconstric3onofbloodvessels(vasoconstric3on)and heart rate also maintain blood pressure.
