Question

how does a hormone work

Answer 1

While all cells are exposed to hormonescirculating in the bloodstream, not all cells react. Only a hormone's "target" cells, which have receptors for that hormone, will respond to its signal. When the hormone binds to its receptor, it causes a biological response within the cell

$\huge{\boxed{{\bf{❥Answer:-}}}}$

▪️Hormones are the chemical substances secreted by the endocrine glands. Endocrine glands are ductless glands so the hormones are directly poured into the blood stream and carried to all parts of the body. The hormones perform their functions when they reach their particular site of action also called the target site. Thus hormones are produced in a particular part of the body but cause a particular effect in another part of the body.
