4. How do endocrine glands communicate with target organs?
Ans. Endocrine glands communicate with target organs by releasing hormones into the bloodstream. Once in the bloodstream, the hormones travel to specific target organs or tissues, where they bind to specific receptors. This binding triggers a response within the target organ, leading to the desired effect.
