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.
If blood sodium levels are low due to insufficient intake, then urine concentrations will also be low. 1  Decreased urinary sodium levels may indicate dehydration, congestive heart failure, liver disease, or nephrotic syndrome. 2  Increased urinary sodium levels may indicate diuretic use or Addison disease.
