Chapter 44.5, Problem 1LO
Summary Introduction
To characterize: The role of sex steroids in development.
Introduction: The glands of the endocrine system are termed as the endocrine glands. These glands directly secrete their secretions (hormones) into the blood without the use of any kind of ducts. Sex steroid hormones are secreted by the reproductive organs such as ovary and testes.
