About This Chapter

The Reproductive System chapter of this Holt McDougal Modern Biology textbook companion course helps students learn essential modern biology lessons on the reproductive system. Each of these simple and fun video lessons is about five minutes long and is sequenced to align with the Reproductive System textbook chapter.

How it works:

  • Identify the lessons in the Holt McDougal Modern Biology Reproductive System chapter with which you need help.
  • Find the corresponding video lessons within this companion course chapter.
  • Watch fun videos that cover the reproductive system topics you need to learn or review.
  • Complete the quizzes to test your understanding.
  • If you need additional help, rewatch the videos until you've mastered the material or submit a question for one of our instructors.

Students will learn:

  • Anatomy and functions of the male reproductive system
  • Functions of the accessory glands of the male reproductive system
  • Testicular anatomy
  • External anatomy of the male reproductive system
  • Sperm's path from the testes to the urethral orifice

Male Reproductive System: Functions, Organs & Anatomy

1. Male Reproductive System: Functions, Organs & Anatomy

Ever wonder what the inside of a male looks like? Find out in this lesson that explores the inner workings of the male reproductive system and the pathway that sperm takes.

Male Reproductive System: Accessory Gland Functions

2. Male Reproductive System: Accessory Gland Functions

Males require a number of different glands to aid in the production of semen. Find out more about those glands in this lesson covering the male accessory glands.

Testicular Anatomy: Structure, Terms & Diagrams

3. Testicular Anatomy: Structure, Terms & Diagrams

Ever wonder about where sperm is made? Find out in this lesson covering the function and anatomy of the male testes. We'll talk about sperm and testosterone production and how the two work together.

Male Reproductive System: External Anatomy

4. Male Reproductive System: External Anatomy

Learn about the structure and function of the external reproductive structures of the male. This includes study of the scrotal sac, the parts of the penis and the erectile tissues.

Sperm's Journey from the Testes to Urethral Orifice

5. Sperm's Journey from the Testes to Urethral Orifice

Follow newly created sperm as they make their way from their origin of creation, the male testes, all the way to the exit of the male reproductive tract.

Female Reproductive System: Internal Anatomy

6. Female Reproductive System: Internal Anatomy

Ever wonder where a female produces her eggs or how they get from the ovary to the uterus? Find out in this lesson about the internal reproductive anatomy of females.

External Anatomy of the Female Reproductive System

7. External Anatomy of the Female Reproductive System

We all know that men and women are different. But just how different are they? Learn a little more about the differences between men and women in this lesson on female external reproductive anatomy.

Phases of The Ovarian Cycle: Overview from Puberty to Menopause

8. Phases of The Ovarian Cycle: Overview from Puberty to Menopause

Just like the human body has to grow and mature before it is ready to reproduce the female's gamete, the egg also has to grow and mature. This lesson will introduce the process through which that occurs, the ovarian cycle.

Follicular Phase of the Ovarian Cycle

9. Follicular Phase of the Ovarian Cycle

The female gamete, the oocyte, grows and matures in a process known as the ovarian cycle. Learn about the first part of the ovarian cycle, the follicular phase, in this lesson.

Luteal Phase of the Ovarian Cycle

10. Luteal Phase of the Ovarian Cycle

Each month, the ovaries recruit and mature a subset of oocytes in preparation for ovulation. Learn what happens after ovulation occurs in the second phase of the ovarian cycle, known as the luteal phase.

The Uterine Cycle: Phases and Endometrial Changes

11. The Uterine Cycle: Phases and Endometrial Changes

Just like a woman's ovaries go through the monthly cycle of recruiting eggs, her uterus also goes through a monthly cycle as it prepares for the possible implantation of a fertilized egg. This lesson will introduce you to the phases and hormones of the female's uterine cycle.

Fertilization and Zygote Formation: Definition and Processes

12. Fertilization and Zygote Formation: Definition and Processes

Follow the male's sperm and the female's egg on their way to meet each other in this lesson that takes you through the process of fertilization in humans. Learn about the obstacles the sperm must get through before it can fertilize the egg.

Early Embryonic Development: The Morula and Blastula

13. Early Embryonic Development: The Morula and Blastula

This lesson on the early stages of mammalian development covers the processes following fertilization, such as cleavage, the morula formation and blastula formation. Watch to learn what the inner cell mass, trophoblast cells and blastocyst are, as well as their functions within embryonic development.

Embryo Implantation and Placenta Formation

14. Embryo Implantation and Placenta Formation

This lesson will cover the journey the mammalian embryo first makes after it has been fertilized. Learn how maternal blood moves through the embryo, and how the placenta is formed.

The Placenta and the Fetus: Structure and Function

15. The Placenta and the Fetus: Structure and Function

Have you ever wondered how a baby eats before it's born or if babies go to the bathroom while still inside their mother? In this lesson, you will learn about the placenta and how it works to ensure a fetus stays well-nourished and healthy before birth.

Amniotic Fluid, The Amnion, and the Yolk Sac

16. Amniotic Fluid, The Amnion, and the Yolk Sac

From a chick developing inside an egg to a human baby growing in its mother's womb, all developing vertebrates rely on a support system to protect them, feed them, supply them with oxygen, remove wastes, and do much, much more to ensure that the embryo grows and develops into a fully functional organism. In this lesson, you'll learn about the different parts of that support system and some of the things that they do.

Gastrulation and the 3 Germ Layers (Ectoderm, Endoderm & Mesoderm)

17. Gastrulation and the 3 Germ Layers (Ectoderm, Endoderm & Mesoderm)

Gastrulation is a key process in embryonic development - it's how a simple ball of cells begins to grow into a fully functioning being! Watch this lesson to learn about a key process in the development of almost all multicellular organisms.

Fetal Development in the First Trimester: Stages & Timeline

18. Fetal Development in the First Trimester: Stages & Timeline

We all know it takes 9 months for the baby to develop inside the mother's womb, but have you ever thought about how or when all those different organs and systems appear? When does the fetal heart start beating or the brain develop? Find out in this lesson covering the first trimester of pre-natal development.

Second Trimester Fetal Development

19. Second Trimester Fetal Development

The growth and development of a baby is an amazingly detailed and complex process. It starts with a ball of cells, which grows all the way to a full grown, eight pound baby in nine months! In this lesson, learn about what happens during the second trimester of pregnancy.

Third Trimester Fetal Development

20. Third Trimester Fetal Development

This is it - the last step, the last few months before the birth of a baby! Learn about the changes the developing fetus goes through during the third and final trimester.

Childbirth: The Role of Hormones in Labor and Delivery

21. Childbirth: The Role of Hormones in Labor and Delivery

How does a mother's body know when it is time to give birth? How does the labor process begin and end? Learn the answers to these questions in this lesson on the hormones involved in childbirth.
