Sodium Intake
Sodium is a mineral that is present only in small quantities in most natural foods, but salt is added, often in large amounts, in food processing and by cooks to enhance flavor. Sodium is the predominant ion in extra cellular fluid.
Sodium (Na) is the predominant cation in extra cellular fluid and its concentration is under tight homeostatic control. Excess dietary sodium is excreted in the urine. The kidney very efficiently reabsorbs the mineral when intakes are low or losses are excessive. Sodium consort with potassium, the chief cation of intracellular fluid, to maintain proper body water distribution and blood pressure. Sodium also is important in maintaining the proper acid-base balance and in the transmission of nerve impulses.
It is a n essential mineral found in the bones and the fluids surrounding cells. It generally works with potassium. Sodium is a constituent of body secretions like saliva and enzymes. Since it is lost when the body sweats, supplements are needed during hard labor on hot days. Sodium may be beneficial for the treatment of diarrhea, leg cramps, dehydration, and fever.

Sodium is vital component of nerves as it stimulates muscle contraction. Sodium also helps to keep calcium and other minerals soluble in the blood, as well as stimulating the adrenal glands. High sodium levels can cause high blood pressure. Sodium aids in preventing heat prostration or sunstroke
Sodium functions with chloride and bicarbonate to maintain a balance of positive and negative ions (electrically charged particles) in our body fluids and tissues. The body receives sodium primarily in the form of table salt (sodium chloride). Sodium, the principal extra cellular ion, has the property of holding water in body tissues.
The appropriateness of current recommendations for the general healthy population to reduce sodium intake has been a matter of debate in the scientific community. Public health scientists generally support the population-wide approach, while

    The purpose is to demonstrate the role of the kidneys in the homeostatic control of extracellular fluid volume, plasma ionic concentrations, and osmolality. Three treatment groups were utilized: a Gatorade group, salt-loaded (access to 0.9 g/l00 ml NaCl) group, and a group who only had water. In this experiment the class was able to observe and analyze the changes in urine production as a means of determining the amount of salt the body gets on a day-to-day basis.…

    Sodium ions need channels in order to move into and out of cells because they are unable to move through the membrane by simple diffusion because of the phospholipid molecules that make up the membrane. This means that the membrane will (for the most part) not allow things with polar molecules to cross such as water and ions. The channels create a “passageway” that allows the Na+ ions to easily pass through…

    It came about because Sodium is a positively charged ion, and it has one electron in its outermost shell. Chlorine, and negatively charged ion it has seven electrons in its outermost shell. So then sodium transfers its one electron to the chlorine, because for sodium to have a full shell it would need to have seven more electrons to make a complete shell.…

    Because the sodium ion is positively charged, it attracts the negatively charged portion of the water molecule (the oxygen atom) and repels the positively charged portion of the water molecule (the hydrogen atoms). Because the chloride ion is negatively charged, it attracts the positively charged portion of the water molecule and repels the negatively charged portion.…
