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.

Why do living things sleep
Tju [1.3M]
There are many theories about why living thins sleep, however, scientists are still unsure about what the answer to this question may be. Some say it is because of its restorative powers - after a good night's sleep, you feel rested, and all your brain and bodily functions work better than when you are exhausted. During sleep, some rejuvenating and growth hormones are created, which again adds to our advantage. You also relieve stress that has accumulated during the day. These are some of the reasons why we have to sleep.
