Which of the following is an incorrect statement regarding vasopressin (ADH)?
ADH deficiency leads to diabetes insipidus, not diabetes mellitus.
Ref: NCERT Class 11 Biology Chapter 19: Chemical Coordination and Integration Endocrine Disorders
Which hormone is responsible for the regulation of water balance in the body?
ADH (Vasopressin) helps in water reabsorption in the kidneys, reducing water loss in urine.
Ref: NCERT Class 11 Biology Chapter 19: Chemical Coordination and Integration Mechanism of Hormone Action - Second Messengers
Which hormone is responsible for maintaining water balance by reducing urine output?
Vasopressin (ADH) promotes water reabsorption in the kidneys, reducing urine output.
Ref: NCERT Class 11 Biology Chapter 19: Chemical Coordination and Integration Mechanism of Hormone Action - Second Messengers
Which hormone is responsible for the regulation of water reabsorption in the kidneys?
Vasopressin (ADH) promotes water reabsorption in the kidneys, reducing urine output and maintaining water balance.
Ref: NCERT Class 11 Biology Chapter 19: Chemical Coordination and Integration Parathyroid Gland and Thymus
Which hormone is secreted in response to dehydration and helps retain water in the body?
ADH (Vasopressin), secreted by the posterior pituitary, promotes water reabsorption in the kidneys to prevent dehydration.
Ref: NCERT Class 11 Biology Chapter 19: Chemical Coordination and Integration Endocrine System and Hypothalamus Pituitary Axis
Which hormone, secreted by the posterior pituitary, plays a role in kidney water retention?
Vasopressin (ADH), secreted by the posterior pituitary, promotes water reabsorption in the kidneys, reducing water loss in urine.
Ref: NCERT Class 11 Biology Chapter 19: Chemical Coordination and Integration Endocrine System and Hypothalamus Pituitary Axis
Which part of the pituitary gland releases vasopressin?
Vasopressin (ADH) is stored and released by the neurohypophysis (pars nervosa) of the posterior pituitary.
Ref: NCERT Class 11 Biology Chapter 19: Chemical Coordination and Integration Endocrine System and Hypothalamus Pituitary Axis
Which of the following conditions is associated with an absence of ADH?
Diabetes insipidus is caused by a deficiency of ADH, leading to excessive urine output and dehydration.
Ref: NCERT Class 11 Biology Chapter 16: Excretory Products and their Elimination Micturition Disorders and Accessory Excretory Organs
Which hormone increases water permeability in the collecting duct?
Antidiuretic hormone (ADH) increases water reabsorption in the collecting duct by making it more permeable to water.
Ref: NCERT Class 11 Biology Chapter 16: Excretory Products and their Elimination Regulation of Kidney Function - RAAS ADH ANF
Which hormone regulates water reabsorption in the kidney?
ADH (Vasopressin) increases water reabsorption in the kidney tubules to reduce water loss.
Ref: NCERT Class 11 Biology Chapter 16: Excretory Products and their Elimination Regulation of Kidney Function - RAAS ADH ANF
Which of the following statements about ADH is incorrect?
ADH does not promote sodium excretion; it regulates water reabsorption to prevent dehydration.
