travel freely, excess is excreted
Characteristics of fat soluble vitamins - (answers)absorbed into the lymph and
then blood, require a lipid protein carrier, excess accumulates in liver and adipose
tissues
Function of fluid - (answers)to dissolve and transport substances, account for
blood volume, maintain body temp, protect and lubricate body tissues.
Function of water - (answers)electrolyte balance, metabolic reactions,
Sources of water - (answers)beverages, food high in water content, water as a
product of metabolic reactions (10-14%)
Body composition of fluid - (answers)2/3 is intracellular 1/3 is extracellular
Regulation of blood volume - (answers)the kidney- ADH says don't pee,
aldosterone signals kidneys to retain electrolytes and indirectly water as well.
