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.

Male Reproductive System: External Anatomy

3. 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.

Female Reproductive System: Internal Anatomy

4. 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

5. 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.

Fertilization and Zygote Formation: Definition and Processes

6. 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

7. 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

8. 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

9. 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

10. 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.

External Genital Development in Males and Females

11. External Genital Development in Males and Females

The developed genitals of a male look much different than the developed genitals of a female. However, they both grow from identical sets of tissues. Learn more about external genital development and find out how and when the tissue changes.

Fetal Development in the First Trimester: Stages & Timeline

12. 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

13. 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

14. 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.
