Explanation Correct answer: Option (d) is correct as it includes brain and kidneys as the options. Explanation/justification for the correct answer: Option (b) is ‘hypothalamus’. The hypothalamus is a part of the brain that contain osmoreceptors. The role and function of these osmoreceptors is to govern water balance as they can detect any change in the plasma osmolarity. This results in expansion and contraction of the cells when the plasma osmolarity is low and high respectively. These osmoreceptors can also stimulate the vasopressin hormone which is responsible for regulating normal plasma osmolarity. When the hypothalamus receives signals from these osmoreceptors of an increased plasma osmolarity, the feeling of thirst is created by the brain. Option (c) is ‘kidney’. The other way of regulating water balance in the body is the renin angiotensin system...

Summary Introduction

Introduction:

Water plays a crucial role as it helps in maintaining homeostasis and it constitutes major composition of the cells and the body. Water is lost from our body while running, urinating, perspiration and sweating. So, it is very important that the water balance is maintained to carry normal physiological activities. To regulate the water balance in human body, brain and kidneys play a pivotal role.
