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.
Primary symptoms associated with too much or too little sodium affect the nervous system and include confusion, lethargy and muscle twitching. Alterations in sodium are connected to changes in the amount of water in the blood because sodium draws water. Decreased sodium lowers blood volume, causing the blood pressure to drop and the heart rate to increase. Sodium increases raise blood volume and cause fluid to accumulate, forcing your heart to work harder.
