All Rights Reserved Multiple Effects of Hormones (호르몬의 다양한 효과) • Many hormones elicit more than one response (많은 호르몬이 한 가지 이상의 반응을 유도함) • For example, epinephrine (에피네프린) is secreted by the adrenal glands and can raise blood glucose levels, increase blood flow to muscles, and decrease blood flow to the digestive system (예를 들어, 에피네프린은 부신에서 분비되며 혈당 수치를 높이고 근육으로 가는 혈류를 증가시키며 소화 기관으로 가는 혈류를 감소시킬 수 있다) • Target cells vary in their response to a hormone because they differ in their receptor types or in the molecules that produce the response (표적 세포는 수용체 유형이나 반응을 생성하는 분자가 다르기 때문에 호르몬에 대한 반응이 다양하다) Copyright © 2021 Pearson Education Ltd.
