Question

Quizplus · Accepted Answer

Endorphins are natural painkillers produced by the body that are released in response to physical activity, such as running. They can also contribute to feelings of happiness and euphoria, which may explain why the friend feels extra happy after a run. Releasing hormones stimulate the release of hormones from other glands, such as the adrenal gland or ovaries. Prolactin is a hormone involved in lactation and milk production. Ibuprofen is a non-steroidal anti-inflammatory drug that is used to treat pain and inflammation, but it is not produced by the body.
