The finer-size sand and clay which fill the spaces between the larger clasts is often deposited later on top of the large clasts and then sifts down between them to fill the interstitial spaces. The deposition of a chemical cement then binds the sediment into a rock. Conglomerate has very few commercial uses.
The brain is particularly sensitive to changes in the sodium level in blood. Therefore, symptoms of brain dysfunction, such as sluggishness (lethargy) and confusion, occur first. If the sodium level in blood falls quickly, symptoms tend to develop rapidly and be more severe.
A blood sodium test may be ordered when a person has symptoms of low sodium, such as weakness, confusion, and lethargy. If the sodium level falls quickly, the person may feel weak and fatigued; in severe cases, the person may experience confusion or even fall into a coma.
