  1. adrenaline is also called as emergency hormone .
  2. we are advised to consume iodised salt .

Adrenaline is also called an emergency hormone because it is released by the adrenal glands under the conditions of stress or excitement. It is a part of body's stress response: fight or flight response. It performs various functions in the body like increasing the supply of glucose to the cells, increasing heart beat to make it pump faster and dilates air passages which constrict blood vessels.

Iodine is required for the proper functioning of the thyroid gland. Its deficiency is called goitre. Hence we should consume iodized salt to supply iodine to our body.

[ii]iodine is necessary for the synthesise of thyroxin hormone by the thyroid glands. thyroxin regulates carbohydrate,protien and fat metabolism in the body.its balanced secretion promotes proper growth.a defficieny of iodine in our diet may lead to goitre,swollen neck and other metabolic disorder.iodine is needed in very small quantity to synthesis thyroxin.iodised common salt contain proper content of iodine.to avoid defficiency of iodine,iodised salt is recommended
