When substances move across the plasma membrane of a cell, they do so while either going down the concentration, which means from higher concentration to lower concentration, or against the concentration gradient, which means from lower concentration to higher concentration.

Passive transport occurs when movement is down the concentration gradient; whereas, active transport, which involves the use of energy, occurs against the concentration gradient.

Plasma contains more sodium than chloride. How can this be if individual ions of sodium and chloride exactly balance each other

MAXImum [283]

In addition to chloride, there are other negatively charged molecules in plasma. The extra sodium restores the balance of the overall negative charges.

So this is how plasma is electrically neutral.

<h3>The makeup of bodily fluids:</h3>

High levels of sodium, chloride, bicarbonate, and protein can be found in the plasma.
High levels of salt, chloride, and bicarbonate but a relatively low level of protein can be found in the IF.
The ICF, on the other hand, contains higher levels of protein, phosphate, magnesium, and potassium.

<h3>What occurs when the plasma Na+ content rises?</h3>

Although the plasma sodium concentration does not provide any information regarding the volume of extracellular fluid, it does allow for an assumption regarding intracellular volume.
A rise in plasma sodium (plasma osmolality) causes water to be drawn out of the cell, which causes the intracellular volume to decrease.

<h3>Why does plasma have a higher sodium content than chloride?</h3>

In plasma, sodium predominates over chloride.
In addition to chloride, there are other negatively charged molecules in plasma.
The extra sodium restores the balance of the overall negative charges.
