Harmless and beneficial bacteria far outnumber harmful varieties. Thousands of bacterial species live commensally in humans, and many provide health benefits to humans, aiding in digestion, for example, or helping to prevent the establishment of colonies of pathogenic bacteria.armless and beneficial bacteria far outnumber harmful varieties.

ADH (Antidiuretic Hormone) The brain and kidneys regulate the amount of water excreted by the body. When the blood volume is low, the concentration of solutes in the blood is high. When the hypothalamus senses this low blood volume and increased serum osmolality it synthesizes ADH, a small peptide molecule.
Antidiuretic hormone (ADH) is produced by an area of the brain called the hypothalamus. ADH controls how your body releases and conserves water. Antidiuretic hormone (ADH) is produced by an area of the brain called the hypothalamus. This hormone is stored in and released by the pituitary gland. ADH controls how your body releases and conserves water. When ADH (also called vasopressin) is produced in excess, the condition is called syndrome of inappropriate antidiuretic hormone (SIADH). This overproduction can occur in places other than the hypothalamus.
