what organ systems are involved in fluid regulation?

Expert Solution

Fluid regulation

Osmotic regulation controls body fluids relative to the osmotically active solutes in the body and this mechanism is called fluid regulation.

Intake(2.2L/ day) + Metabolic production - Output ( 0.9+ 0.1) = 0

Thirst mechanism

It is the body's response to changes in the blood volume and changes in osmolality. The physiological control of thirst is the backup mechanism to increase water input

Organs that are involved in fluid regulation

Kidneys

It has many protein sensors which detects blood volume and blood pressure
Low blood volume and decreased blood pressure make kidney secrete renin
Renin travels in the blood and converts angiotensionogen to angiotensin
The production of ADH by the stimulation of kidney targets adrenal glands,hypothalamus

2. kidneys

Osmoreceptors present in hypothalamus detects sodium concentration in the blood
In high sodium level, hypothalamus activates the third mechanisms stimulate the release of ADH and increases blood osmolality.

3. Adrenal glands

Adrenal glands sense for sodium and potassium levels in the body
Aldosterone is released in response to angiotensin stimulation and will increase water renal bsorptisn
