Effects of stress on memory from the adrenal gland. These substances are the main factors responsible for the stress response in humans. Cortisol for example stimulates the mobilization of free fatty acids and proteins and the breakdown of amino acids, and increases serum glucose level and blood pressure, among other effects. On the other hand, aldosterone is responsible for water retention associated with stress. As a result of cells retaining sodium and eliminating potassium, water is retained and blood pressure is increased by increasing the blood volume. A second physiological response in relation to stress occurs via the vasopressin axis. Vasopressin, also known as antidiuretic
