Bisphenol-A (BPA) BPA is used in hard, clear plastic, like baby bottles. Phthalates help make plastic, like pacifiers, flexible. It is believed that both BPA and phthalates can leach from plastic into food, liquid, and directly into the mouths of children while sucking on pacifiers or teethers. When you have something plastic, look at the little triangle on the bottom of the container. 2  Avoiding plastic containers marked with a 1 or a 7 pc and instead choosing those marked with a 2, 4, or 5 will reduce the likelihood of exposure to BPA and phthalates.

Hormone A hormone (from Greek ὁρμή, impetus) is any member of a class of signaling molecules produced by glands in multicellular organisms that are transported by the circulatory system to target distant organs to regulate physiology and behaviour.ne special group of hormones is the tropic hormones that stimulate the hormone production of other endocrine glands. For example, thyroid-stimulating hormone (TSH) causes growth and increased activity of another endocrine gland, the thyroid, which increases output of thyroid hormones.

- Growth hormone (GH or HGH), also known as somatotropin or somatropin, is a peptide hormone that stimulates growth, cell reproduction and regeneration in humans and other animals.It is a type of mitogen which is specific only to certain kinds of cells.t also stimulates production of IGF-1. GH is used as a prescription drug in medicine to treat children's growth disorders and adult growth hormone deficiency. In the United States, it is only available legally from pharmacies, by prescription from a doctor.

Co-ordination and Response Hormones are chemical substances produced by a gland, carried by the blood, which alters the activity of one or more specific target organs and is then destroyed by the liver. Hormones are produced in organs called endocrine glands which make up the endocrine system.The following diagram shows the glands of a human body. Glands are organs made of secretory cells which’s function is to produce hormones and secret them into the bloodstream.ormones are produced in organs called endocrine glands which make up the endocrine system.

What are Hormones? Hormones are chemicals that carry messages from glands to cells within tissues or organs in the body. They also maintain chemical levels in the bloodstream to help achieve homeostasis, which is a state of stability or balance within the body. There are two types of these chemicals, known as steroids and peptides. The word hormone comes from a Greek word that means to spur on..

Estrogen and Testosterone Hormones The definition of a hormone is a chemical substance produced by an endocrine gland that has a specific effect on the activities of other organs in the body. The major female and male hormones can be classified as estrogens or androgens.Both classes of male and female hormones are present in both males and females alike, but in vastly different amounts.Most men produce 6-8 mg of the male hormone testosterone (an androgen) per day, compared to most women who produce 0.5 mg daily.Female hormones, estrogens, are also present in both sexes, but in larger amounts for women.oth classes of male and female hormones are present in both males and females alike, but in vastly different amounts.

Growth hormone Growth hormone (GH or HGH), also known as somatotropin or somatropin, is a peptide hormone that stimulates growth, cell reproduction and regeneration in humans and other animals. It is a type of mitogen which is specific only to certain kinds of cells. Growth hormone is a 191- amino acid, single-chain polypeptide that is synthesized, stored, and secreted by somatotropic cells within the lateral wings of the anterior pituitary gland. GH is a stress hormone that raises the concentration of glucose and free fatty acids. It also stimulates production of IGF-1. GH is used as a prescription drug in medicine to treat children's growth disorders and adult growth hormone deficiency. In the United States, it is only available legally from pharmacies, by prescription from a doctor.
