Endocrine glands are the ductless glands which secrete their products (hormones) directly into the blood. The hormones then reach the target organ and cause changes in their regulation and functioning.

• Pituitary gland is the master gland that regulates the activity of other endocrine glands and secretes many hormones like growth hormone, follicle stimulating hormone, thyroid stimulating hormone etc.
• Thyroid gland secretes thyroxine hormone that regulates metabolic rate of body.
• Adrenal glands consist of two parts, adrenal cortex that secretes corticoids and adrenal medulla that secretes adrenaline and noradrenaline.
• Ovary secretes estrogen which stimulates development of sex organs and sexual characters.
• Testis secrete testosterone, the principle androgen in males that stimulate spermatogenesis and development of sexual characters.

So, the correct answer is 'Pituitary, Thyroid, Adrenals, Ovary, Testis'.
