Fluid and hormone regulation in the body to maintain fluid homeostasis. Hormones used for fluid balance include the following: ADH (antidiuretic hormone/vasopressin), Aldosterone, Natriuretic Peptide hormones: ANP (atrial natriuretic peptide) and BNP (brain natriuretic peptide). In addition, the body uses systems like the RAAS (renin-aldosterone-angiotensin system) and the thirst mechanism to achieve a fluid balance.
ADH (antidiuretic hormone) causes the kidneys to keep water, which increases blood volume. This hormone acts on the distal convoluted tubule and collecting duct of the nephron. Aldosterone is made by the hypothalamus and is stored and secreted by the posterior pituitary gland. It causes the body to keep sodium and water to increase blood volume.
The RAAS creates angiotensin II and this causes vasoconstriction along with enhancing the role of ADH and aldosterone. Furthermore, it stimulates the thirst mechanism. The thirst mechanism is controlled by the hypothalamus, specifically the osmoreceptors. These receptors cause ADH to be released and the thirst sensation is experienced.
For more in depth information on these hormones and body systems that maintain fluid regulation check out the video above.
