1 FEMALE AND MALE ANATOMY 7 TH GRADE

2 GOALS Identify the parts of the male and female reproduction systems Explain the three functions of the female reproduction systems Identify problems of the male and female reproduction sysytem Describe ways to keep it healthy

3 What do you think the single most important thing teens can do to care for their reproduction system? Type 1 Three sentences

4 K8 K8 Getting through puberty

5 Define reproductive system? The bodies system containing the organs that make possible the production of offspring.

6 Define secondary sex characteristics Development of physical characteristics of adults of your gender FEMALE MALES..

7 MALES 3.: are the male reproductive glands that produce testosterone, the male hormone. a.The testes produce sperm, the male sex gland. 4. : are stored in the epididymis, a network of tubes located behind the testes. 5.when the sperm are ready to leave the epididymis, they pass through the.

8 Here they mix with secretions from the seminal vesicles, the prostate gland, and the Cowper’s gland. The mixture of fluids and sperm is called Semen exits the penis through, a series of forceful muscular contractions.

9 6.The gland is about the size and shapes of a chestnut that secrets nutrients and neutralizing fluids into the semen. Also squeezes shut the urethral duct to the bladder. 7. Is a small tube leading from the bladder to the glands. The urethra releases both sperm and urine.

10 8. Is the tubes that extend from each epididymis to the urethra. Propels the live sperm from their storage site. When a male has a VASECTOMY, this is “tied off” to prevent sperm from reaching the body’s exterior.

11 Problems of the Male 9.Injury to the tetes; wearing appropriate protective gear during sports is one way to avoid injury. 10.Cancer of males from ages 14 – 34: : can spread to the other parts of the body if not dtected and treated early there is an excellent change of recovery

12 11.Occurs when an internal organ pushes against or through a surrounding cavity wall. It appears as a lump or swelling in the groin or lower abdomen. Caused by muscle weakness and strain. Can be corrected with surgery. 12.Sexually transmitted diseases: end result can be sterility.

13 Female Reproduction The female system is to store egg cells and the second funtion is to create offspring or babies through the process of fertilization.

14 13.What is fertilization? when a males’s sperm cell joins with the females egg cells. 14.The egg travels from the ovaries through the fallopian tube to the uterus where it attches to the wall of the uterus and begins to grow. 15.During the first 8 weeks, the fertilized egg is call an. 16.After 8 weeks the embryo becomes a 17.In approximitly nine months, the fetus is ready to be born. This is where the third function of the female system occurs -

15 During Puberty 18.Is the release of one mature egg cell each month. The egg follows the process of decent to the uterus. 19.If the egg is not fertilized, the lining of the uterus breaks down and is shed by the body through. 20.

16 20.Is when the lining material, the unfertized egg, and some blood flow out of the body. This usually lasts 5-7 days and will occur every 28 days. The cycle is called. 21.During this time hormonal changes occur in females from the beginning of one menstruation to the next.

17 22.What are the ovaries? Contain the ova, or eggs and produce hormones.

18 23. carry eggs from the ovaries to the uterus. 24. shelters and nourishes the fetus. 25. the ENDOMETRIUM is the lining of the uterus. 26. is the opening of the uterus. 27. is a muscular passageway from the uterus to the outside of the body.

19 Problems of the female system Among the differernt problems with the female system, cancer can occur in the ovaries, uterus or cervix.

20 28. Is the inablility to get pregrant. It may be due to blocked fallopian tubes or a failure to produce eggs. 29.Are growths on the ovary. Sysmptoms of the cysts include a feeling of heaviness in the abdomen and abdominal pain, swelling and bloating. 30. STD’s are spread through sexual contact.

21 SEX EDUCATION ABSTINENCE Safe sex Sexual attitude Sexual behaviors Sexual health Sexual orientation

30 After fertilization of the egg and the sperm A baby is made

31 The fertilization takes place in the mothers reproductive system. The egg and the sperm fertiize in one of her fallopian tubes. As soon as the sperm cell meets the egg cell, a film is produced around the egg. This prevents any additional sperm cells from entering the egg cell. Once fertilization takes place, a new life begins to grow

32 Growing during pregnancy 31. Once the egg is fertilized it travels from the tubes to the - the organ where the embryo is protected and nourished. The cell begins to divide during a process known as. After 3 weeks the embryo is formed.

33 32.After 8 weeks cells combine forming tissue, to form organs and organs form systems. The embryo is now a. 33. in order for the baby to grow, it must get food from its mother and this is from the - a thick, rich tissue that lines the walls of the uterus during pregnancy and that nourishes the fetus. 34. the fetus gets food and oxygen through a blood vessel in the - a tube that connects the mother’s placenta to the fetus. Any unwanted substances can harm the fetus.

34 RbV33J5qk Growth of the baby

35 Stages of birth 35. Stage 1: Muscles in the uterus begin to squeeze and release gently. The muscle movement is called a contraction. At this point the entry of the uterus : begins to dilate or open. 36. Stage 2: The cervix continues to dilate, preparing for the baby to pass through. Contractions become very strong helping push the baby through the cervix down the birth canal out of the mother’s body.

36 37. Stage 3: once the baby is born, the placenta is no longer needed. The muscles to the uterus keep contracting until the placenta is pushed out of the mother.

37 Birth defects/genetic disorders 38. When genes from one or both parents are abdormal or changed in some way a baby can be born with a GENETIC DISORDER – disorder caused partly or completely by a defect in genes. A defect is a flaw or the absence of something needed.

38 A.May occur when a fertized egg has more or fewer than 46 chromosomes. B. People with down syndrome have an extra chromosome that causes them to have certain facial features and learning disabilities. C. sickle-cell anemia is a blood disorder caused by an abdnormal gene. People with this disorder have abnormally shaped red blood cells that can block blood vessels and cause pain in the bones and joints.

39 Physical and mental disabilities or death Good prenatal care can help prevent birth defects Poor nutrition – baby relies on he mother’s good health eating habits. If the mother has poor eating havits the baby could be born premature – which can cause physical or mental health problems. Alcohol/drugs/medicines Infections – woman develops infection it can cause serious harm to fetus. Miscarry…..
