Unit 3 Lesson 6 The Reproductive System Florida Benchmarks SC.6.N.3.4 Identify the role of models in the context of the sixth grade science benchmarks. SC.6.L.14.5 Identify and investigate the general functions of the major systems of the human body (digestive, respiratory, circulatory, reproductive, excretory, immune, nervous, and musculoskeletal) and describe ways these systems interact with each other to maintain homeostasis.

Unit 3 Lesson 6 The Reproductive System Florida Benchmarks MA.6.A.3.6 Construct and analyze tables, graphs, and equations to describe linear functions and other simple relations using both common language and algebraic notation. HE.6.C.1.8 Explain how body systems are impacted by hereditary factors and infectious agents. Copyright © Houghton Mifflin Harcourt Publishing Company 3

Unit 3 Lesson 6 The Reproductive System Reproduction What are the main functions of the male reproductive system? Sperm are the male cells that carry 23 chromosomes and are used for reproduction. Testes are the main organs of the male reproductive system that produce the male sex hormone testosterone. Testosterone, the male sex hormone, causes male characteristics to develop. Copyright © Houghton Mifflin Harcourt Publishing Company 4

What are the main functions of the male reproductive system? Unit 3 Lesson 6 The Reproductive System What are the main functions of the male reproductive system? The testes make sperm, which are stored in the epididymis. Sperm leave the epididymis through the vas deferens and mix with fluids to produce semen. To leave the body, semen passes through the urethra in the male sex organ, called the penis. Copyright © Houghton Mifflin Harcourt Publishing Company 5

What are the main functions of the male reproductive system? Unit 3 Lesson 6 The Reproductive System What are the main functions of the male reproductive system? How is sperm produced in the male reproductive system? Copyright © Houghton Mifflin Harcourt Publishing Company 6

What are the main functions of the female reproductive system? Unit 3 Lesson 6 The Reproductive System What are the main functions of the female reproductive system? An egg is the female sex cell. It carries 23 chromosomes. The female reproductive hormones, estrogen and progesterone, control the development of female characteristics and the release of eggs. An ovary is the reproductive organ that produces eggs. Copyright © Houghton Mifflin Harcourt Publishing Company 7

Fertile Ground How are eggs released? Unit 3 Lesson 6 The Reproductive System Fertile Ground How are eggs released? The menstrual cycle is the changes that produce an egg, release the egg, and prepare the body for pregnancy. About halfway through the cycle, which is about one month long, an egg is released from the ovary. Copyright © Houghton Mifflin Harcourt Publishing Company 8

Unit 3 Lesson 6 The Reproductive System How are eggs released? The egg travels through the fallopian tube that connects the ovary to the uterus. The uterus is the organ in which a fertilized egg develops into a baby. A baby passes through a canal between the uterus and the outside of the body called the vagina. Copyright © Houghton Mifflin Harcourt Publishing Company 9

Unit 3 Lesson 6 The Reproductive System How are eggs released? Eggs that are not fertilized are shed with the lining of the uterus. The monthly discharge of blood and tissue from the uterus is called menstruation. Copyright © Houghton Mifflin Harcourt Publishing Company 10

How are eggs fertilized? Unit 3 Lesson 6 The Reproductive System How are eggs fertilized? When sperm enters the egg, one cell is formed and fertilization has occurred. Once cell division occurs, the fertilized egg becomes an embryo. The embryo then travels to the uterus and attaches to the thick nutrient-rich lining.

Unit 3 Lesson 6 The Reproductive System How are eggs released? What happens to fertilized eggs in reproduction? What happens to eggs that are not fertilized? Copyright © Houghton Mifflin Harcourt Publishing Company 12

Happy Birthday! What are the stages of pregnancy? Unit 3 Lesson 6 The Reproductive System Happy Birthday! What are the stages of pregnancy? A pregnancy lasts about nine months, which are broken down into three three-month trimesters. The placenta is a network of blood vessels that provides the embryo with oxygen and nutrients from the mother’s blood and carries away wastes. Copyright © Houghton Mifflin Harcourt Publishing Company 13

What are the stages of pregnancy? Unit 3 Lesson 6 The Reproductive System What are the stages of pregnancy? The embryo connects to the placenta by the umbilical cord. The embryo is surrounded by the amnion, a sac filled with fluid that protects the embryo. Copyright © Houghton Mifflin Harcourt Publishing Company 14

What are the stages of pregnancy? Unit 3 Lesson 6 The Reproductive System What are the stages of pregnancy? After week 10 in the first trimester, the embryo is called a fetus. In the second trimester, the fetus develops joints and bones and grows stronger. Copyright © Houghton Mifflin Harcourt Publishing Company 15

What are the stages of pregnancy? Unit 3 Lesson 6 The Reproductive System What are the stages of pregnancy? The fetus begins to make movements the mother can feel in the second trimester. In the third trimester, the brain develops further and the organs become fully functional. A full-term pregnancy lasts about 40 weeks. Copyright © Houghton Mifflin Harcourt Publishing Company 16

Unit 3 Lesson 6 The Reproductive System How are babies born? During labor, the uterus goes through a series of contractions that push the baby through the vagina. The umbilical cord is cut when the baby is born. Once the mother pushes out the placenta, labor is complete. Copyright © Houghton Mifflin Harcourt Publishing Company 17

What changes occur during infancy and childhood? Unit 3 Lesson 6 The Reproductive System What changes occur during infancy and childhood? Babies grow quickly in infancy, which is from birth to about age 2. Childhood lasts from age 2 to puberty. Children learn to speak, gain coordination, get permanent teeth, and experience more as they grow older. Copyright © Houghton Mifflin Harcourt Publishing Company 18

What changes occur during adolescence and adulthood? Unit 3 Lesson 6 The Reproductive System What changes occur during adolescence and adulthood? The stage from puberty to adulthood is adolescence. The reproductive system matures during adolescence. Physical and emotional maturity are reached in adulthood. Copyright © Houghton Mifflin Harcourt Publishing Company 19

Infections What causes STIs? Unit 3 Lesson 6 The Reproductive System Infections What causes STIs? Sexually transmitted infections (STIs) are infections passed during sexual contact. Acquired immunodeficiency syndrome (AIDS) is caused by the human immunodeficiency virus (HIV), which destroys immune-system cells. Copyright © Houghton Mifflin Harcourt Publishing Company 20

Unit 3 Lesson 6 The Reproductive System What causes STIs? Genital herpes, human papillomavirus (HPV), and hepatitis B are other viral STIs. Chlamydia, gonorrhea, are syphilis are STIs caused by bacteria. Trichomoniasis and pubic lice are STIs that are caused by parasites. Copyright © Houghton Mifflin Harcourt Publishing Company 21

Unit 3 Lesson 6 The Reproductive System Seeing Double Multiple birth occurs when two or more babies are carried in the same pregnancy. About 3 percent of all births result in twins, and 0.1 percent of births results in triplets. Identical twins are from one embryo that splits into two. Fraternal siblings are caused by two sperm fertilizing two or more separate eggs. Copyright © Houghton Mifflin Harcourt Publishing Company 22
