The ovary is composed of ovarian follicles and stromal tissues.
It produces the eggs or ova. The ovaries secrete the steroid hormones oestrogen and progesterone. Oestrogen is responsible for the maturation of reproductive organs and the development of secondary sexual characters at puberty.

Since glucagon reduces the cellular uptake and utilisation of glucose it is called a hyperglycemic hormone.
Prolonged hyperglycemia leads to the disorder called diabetes mellitus. Humulin N: Human insulin is produced by recombinant DNA technology (genetic engineering) and administered to diabetic patients as injection and not by oral consumption. Reason: Digestive enzymes digest it. Insulin: The half life period of insulin (in plasma) is minutes It is cleared from the circulation within - minutes Endocrine glands control and coordinate the body functions through secreting certain chemical messengers called hormones.
