WebIf sodium ions are outside of a cell, they will tend to move into the cell based on both their concentration gradient (the lower concentration of Na + ^+ + start superscript, plus, end superscript in the cell) and the voltage across the membrane (the more negative charge … WebActive transport allows cells to move a specific substance against its concentration gradient through a membrane protein, requiring energy in the form of ATP. For example, the sodium-potassium pump employs active transport to pump sodium out of cells and potassium into cells, with both substances moving against their concentration gradients.

As a consequence, blood volume swells, adding pressure to blood vessels. Although the kidneys restore blood salt to physiological levels, recent studies revealed that not all excess salt is effectively eliminated. WebSodium is an electrolyte (mineral). It is very important for maintaining blood pressure. Sodium is also needed for nerves, muscles, and other body tissues to work properly. When the amount of sodium in fluids outside cells drops below normal, water moves into the cells to balance the levels.
