1 - h Testosterone is the male sex hormone that is made in the testicles. Testosterone hormone levels are important to normal male sexual development and functions. During puberty (in the teen years), testosterone helps boys develop male features like body and facial hair, deeper voice, and muscle strength. 2 - f The pituitary gland is a small pea-sized gland that plays a major role in regulating vital body functions and general wellbeing. It is known as 'master gland'. Growth hormone is released into the bloodstream from the anterior pituitary gland. The roles of growth hormone includes influencing our height, and helping build our bones and muscles. 3 - i The pancreas is an organ located in the abdomen. The main hormones secreted by the endocrine gland in the pancreas are insulin and glucagon, which regulate the level of glucose in the blood. 4 - g The ovaries have two main reproductive functions in the body. They produce oocytes (eggs) for fertilisation, and they produce the reproductive hormones, oestrogen and progesterone. 5 - b The adrenal glands are small structures attached to the top of each kidney. It produces “stress hormones,” including adrenaline. 6 - e The thyroid gland is a vital hormone gland: It plays a major role in the metabolism, growth and development of the human body. It produces thyroxine. 7 - d Menstruation, or period, is normal vaginal bleeding that occurs as part of a woman's monthly cycle. If no pregnancy occurs, the uterus, or womb, sheds its lining. The menstrual blood is partly blood and partly tissue from inside the uterus. 8 - a At 45 to 50 years of age, the menstrual cycle stops. Stoppage of menstruation is termed menopause. Changing levels of oestrogen and progesterone are responsible. 9 - c The first menstrual flow begins at puberty and is termed menarche. Column A Column B 1. Testes h. Testosterone 2. Pituitary f.

Adrenaline hormone is secreted by the adrenal gland which is present just above the kidney. This hormone prepares our body to function at maximum efficiency during emergencies. It is also called epinephrine, this hormone is the main part of the body's fight-or-flight response, but over-exposure can damage our health. Due to this, adrenaline is a hormone worth understanding. Adrenaline is produced in the medulla of adrenal glands as well as some central nervous system's neurons.
