CSF GLUCOSE. 1  Increased CSF glucose is a sign of high blood sugar. 2  Decreased CSF glucose may be due to hypoglycemia (low blood sugar), bacterial or fungal infection (such as meningitis), tuberculosis, or certain other types of meningitis.
Water is an essential nutrient that is involved in every function of the body. 1  Water helps transport nutrients and waste products in and out of cells. 2  Water is necessary for all digestive, absorption, circulatory, and excretory functions. 3  Water is needed for the utilization of the water-soluble vitamins.
Nutrient substances are washed into the system, providing important growth chemicals (eg. nitrates) and sources of food (eg. rotting plants). Water plants, in turn, photosynthesize and provide life-supporting oxygen and other food sources for water organisms that interact in a complex web of life. All life in the water is dependent on the interaction within the river itself and in the surrounding catchment.
