Ch 20: AP Biology - Reproductive Systems: Help and Review

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.

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.

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.

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.

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.

6. The HPG Axis: Hormones of Male Reproduction

Do you know how your body communicates? How does the brain get in touch with other parts of the body? In this lesson, you will learn about how the male's brain uses hormones to communicate to the testes as a way of regulating reproduction.

7. 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.

8. The Uterus and Uterine Wall: Structure and Parts

Learn all about the structure responsible for the development of babies in this lesson on uterine anatomy. Discover the three layers of the uterus and each layer's purpose.

9. 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.

10. HPG Axis: Hormonal Control of the Ovarian Cycle

Everything in the female reproductive system is connected. See how the brain interacts with the ovaries during the female's ovarian cycle in this lesson covering the female HPG axis.

11. 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.

12. 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.

13. 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.

14. 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.

15. The Uterine Cycle: Menses

Each month the female's uterus prepares for the potential of pregnancy. However, pregnancy doesn't occur the majority of the time. In those months, the female's uterus has to 'reset' itself for the next month. It does that during the first phase of the uterine cycle, menses.

16. The Uterine Cycle: Proliferative Phase

A woman's body goes through many changes as it prepares for the possibility of pregnancy. Learn about how the uterus prepares for pregnancy by building up its inner lining during this lesson on the proliferative phase of the uterine cycle.

17. The Uterine Cycle: Secretory Phase

The third (and final) phase of the uterine cycle is the secretory phase. During this phase, the uterine tissue regrowth is completed in preparation for the possibility of pregnancy and the implantation of a fertilized egg.

18. The Female Reproductive Axis: Coordination of the Brain, Ovaries & Uterus

Without proper communication between the brain, ovaries and uterus, reproduction might not be as efficient. Learn about how these organs work together to ensure the body is ready for reproduction.

19. Ovulation to Implantation: Oocyte's Path through Uterine Tubes

Follow the female's egg as it leaves the ovary and travels down the uterine tube on its way to the uterus - all with hopes of meeting up with a male's sperm along the way.

20. Absolute Refractory Period: Definition & Significance

This lesson is on the absolute refractory period, a time when a neuron cannot fire another impulse. This lesson will explain the mechanism behind the absolute refractory period and the function.

21. Relative Refractory Period: Definition & Significance

This lesson is about the relative refractory period - the amount of time that a neuron needs additional stimulus to be able to send an action potential. In this lesson, you will learn how neurons communicate, what the relative refractory period is, and why it is important for our bodies.

22. Gonads: Definition & Function

Learn what the gonads are and examine their functions. We will look into both the male and female gonads. You can take the quiz afterwards to test your understanding of these organs.

23. Human Chorionic Gonadotropin (HCG): Side Effects & Definition

HCG is a reproductive hormone. This lesson will discuss the basics of HCG, the importance of HCG and possible side effects of synthetic HCG used for treatment. Follow along. It will be gland!

24. Endometrial Ablation: Procedure, Recovery & Side Effects

Endometrial ablation is a medical procedures that helps women who suffer from abnormal uterine bleeding. The lesson below outlines what an ablation is, why it is done, basics about the procedure and the recovery and side effects of having the procedure done.
