For our Internet topic we chose to do hormones. Hormones are chemicals that transfer information and instructions between cells in animals and plants. Hormones are also described as the body's chemical messengers. Hormones are responsible in regulating growth and development. Hormones control the function of various tissues.
Hormones support reproductive functions and regulate metabolism.
The endocrine glands produce and secrete hormone directly into the bloodstream. Not all hormones are produced by the endocrine glands. Mucous membranes of the small intestine secrete hormones that stimulate secretion of the digestive juices from the pancreas. Other hormones are produced in the placenta an organ formed during pregnancy. The placenta regulates some aspects of foetal development.
