These are chemical messengers released by endocrine glands and carried through the bloodstream to specific target tissues, where they produce either rapid or long-term effects For the purposes of asthma, hormones secreted by the adrenal glands (located atop the kidneys) known as corticosteroids are of concern
Regulators of various biological processes through their ability to control the action of enzymes Made from proteins, such as insulin for blood sugar control, or cholesterol for testosterone control
A chemical or protein that acts as a messenger or stimulatory signal, relaying instructions to stop or start certain physiological processes Hormones are synthesized in one type of cell and then released to direct the function of other cell types
Substances that act as chemical messengers in the body They are produced in parts of the body called endocrine glands Hormones travel around the body in the blood and control how other parts of the body work For example, parathyroid hormone from the parathyroid glands affects kidney function
Natural chemicals produced by our bodies that are responsible for successful reproduction, development, normal behavior, and maintenance of normal body processes
Substances secreted by various organs of the body that regulate growth, metabolism, and reproduction
Chemical substances produced by glands which circulate in the blood and help control growth, reproduction and other functions
Chemicals produced by glands in the body and circulate in the bloodstream Hormones control the actions of certain cells or organs
Chemicals released into the bloodstream that control different functions in the body, including metabolism, growth, sexual development, and responses to stress or illness
biological chemicals that act as "messengers" in organisms by causing changes in biological processes
Chemicals produced by various glands of the body that regulate the actions of certain cells or organs
Proteins produced by organs of the body that trigger activity in other locations
Chemicals produced by certain glands in the body Hormones control functions of certain cells or organs
Chemicals that travel through the blood stream to deliver messages from one part of the body to another Hormones are produced in specialized areas, such as the ovaries and thyroid glands, and signal other areas, such as the uterus and brain
