4 In this lesson, you will learn to identify the parts and functions of the male and female reproductive systems.explain how to care for the reproductive system.
5 Comparing and Contrasting As you go through this lesson, compare and contrast the female and male reproductive systems.
6 Human ReproductionThe male reproductive system is different than the female reproductive system.reproductive system The body system that makes it possible to create offspringSo far, all the body systems you’ve learned about are the same for females and males. The reproductive system is different.
7 The Female Reproductive System The two main functions of the female reproductive system are:Storing egg cellsTo reproduceThe egg cell is also called an ovum.egg cell The female reproductive cell
8 The Female Reproductive System The process of reproduction begins when the egg cell joins with a male reproductive cell.The ovaries are the two female reproductive glands that store the egg cells.The ovaries also release hormones that control growth and play a role in the proper functioning of the reproductive system. During puberty, the ovaries begin to release eggs.
9 The Female Reproductive System After fertilization, an egg will travel to the uterus, the organ in which the baby will develop.fertilization The joining of a female egg with a male reproductive cell
10 The Female Reproductive System Menstruation is often referred to as a “period.”menstruation Blood, tissue, and the unfertilized egg flow out of the bodyIf fertilization does not occur, the nutrient-rich lining of the uterus breaks down.Most girls can expect to begin menstruation anywhere from age 9 through 16.During menstruation, change sanitary pads or tampons several times a day.Expect some cramping during menstruation. Talk to your doctor if you have unusual pain or heavy bleeding.
11 The Male Reproductive System Sperm cells are made inside the testes.sperm The male reproductive cellsSperm cells travel through the vas deferens to the urethra where they leave the body.The testes also produce a hormone that controls the development of the male reproductive system.The testes begin making sperm cells during puberty.
12 Lesson 2 ReviewWhat I LearnedRecall Name two functions of the female reproductive system.Two functions of the female reproductive system are to produce hormones and reproductive cells.
13 What I Learned Vocabulary Define fertilization. Lesson 2 Review Fertilization is the joining of an egg cell and a sperm cell.
14 Lesson 2 ReviewWhat I LearnedIdentify Where in the male reproductive system are the sperm made?Sperm are made in the testes.
15 Lesson 2 ReviewThinking CriticallyCompare How are the female and male reproductive systems similar? How are they different?They are alike in that both produce and store reproductive cells, but they have different structures.
16 Lesson 2 ReviewThinking CriticallyAnalyze James will be catcher this year for his baseball team. What special precautions should James take to prevent injury to his reproductive system? Give details to explain your answer.He should wear a protective cup. Injury to male reproductive organs could cause sterility.
