For (a) - (v) The pituitary gland is located in a bony cavity and is attached to hypothalamus by a stalk. Growth hormone stimulates growth in all organs. For (b) - (iv) The adrenal gland is an endocrine gland. It is a yellowish colour, with small glands located on top of both the kidneys. It secretes adrenaline hormone. This hormone is released during emergency conditions to prepare the body. For (c) - (vi) Insulin hormone is secreted by the pancreas. This hormone maintains the optimum level of blood glucose in the human body. For (d) - (ii) Thyroxine hormone is secreted by the thyroid gland. This hormone regulates the rate of oxidation of food by cells to generate energy. For (e) - (iii) Testosterone hormone is secreted by testes. This hormone regulates the development of secondary sexual characteristics in both males and it plays a vital role in sperm production. For (f) - (i) Oestrogen hormone is secreted by ovaries. This hormone is responsible for the growth of the secondary sexual characteristics, and regulation of the menstrual cycle and the reproductive system.
