Question

If a person is having increased osmolarity of his body fluid, which center of brain will sense it for remedial action?​

Answer 1

Explanation:

Osmoreceptors are sensory receptors in the thirst center in the hypothalamus that monitor the concentration of solutes (osmolality) of the blood. If blood osmolality increases above its ideal value, the hypothalamus transmits signals that result in a conscious awareness of thirst.

Answer 2

If a person is having increased osmolarity of his body fluid, osmoreceptors in the thirst center of the brain will sense it for remedial action.

• The increased concentration of solutes in body fluids leads to an increase in the level of osmolarity. It is sensed by the osmoreceptors located in the anterior region of the hypothalamus.
• It will then trigger the secretion of vasopressin hormone, also termed as anti-diuretic hormone (ADH).  
• Consequently, water reabsorption is increased and the urine becomes more concentrated.
