Which hormone increases the blood pressure by constricting arterioles during severe haemorrhage?

Which hormone increases the blood pressure by constricting arterioles during severe haemorrhage? Correct Answer Anti-diuretic hormone

Concept:-

  • Vasopressin hormone: also known as an antidiuretic hormone.
  • Secreted by: the neurohypophysis of the pituitary gland.

Functions of vasopressin hormone:

  • Maintains the proper cellular function.
  • It is responsible for homeostasis.
  • It acts on the kidneys and the blood vessels and functions to control blood pressure.
  • It reduces the amount of water excreted through the urine thereby conserving the volume of the fluid in the body.
  • AvP mainly acts on renal collecting ducts through Vasopressor receptor and it further increases the water permeability, leads to lowers the production of urine and increasing the water volume and the cardiac output, and ultimately increases the Blood Pressure.
