Thirst,a conscious desire for water,regulates fluid intake when plasma osmolality increases (osmoreceptor-mediated thirst)or the blood volume decreases (baroreceptor-mediated thirst and angiotensin II-mediated thirst).The thirst-control mechanism is in the hypothalamus of the brain.Osmoreceptors there continually monitor plasma osmolality; when osmolality increases,the hypothalamus stimulates thirst.Colloid osmotic pressure (oncotic pressure)is an inward-pulling force caused by the presence of protein molecules.Hydrostatic pressure is the force of a fluid pressing outward against the walls of its container.Thus capillary hydrostatic pressure is an outward-pushing force.
