Blood Loss. Blood loss is the most common cause of anemia, especially iron-deficiency anemia. Blood loss can be short term or persist over time. Heavy menstrual periods or bleeding in the digestive or urinary tract can cause blood loss. Surgery, trauma, or cancer also can cause blood loss.
second most common cause of acid-base imbalance. recognized by low blood pH and HCO3- levels. indicated by rising blood pH and HCO3- levels, is much less common than metabolic acidosis. typical causes are vomiting of the acidic contents of the stomach and intake of excess base.
Bases and acids are seen as opposites because the effect of an acid is to increase the hydronium (H3O+) concentration in water, whereas bases reduce this concentration. A reaction between an acid and base is called neutralization. In a neutralization reaction, an aqueous solution of a base reacts with an aqueous solution of an acid to produce a solution of water and salt in which the salt separates into its component ions.
