Do Now Objectives Sit down if Purpose Reproduction Male Reproductive System Female Reproductive System Sexual Response System Journal Homework Objectives
Name the parts of the human reproductive system Describe the path of an egg during the menstrual cycle Describe the path of a sperm during ejaculation Recognize that there is a wide range of normal anatomy Name the three main components of sexual response Everyone Stand up
Sit down if... You know someone who is engaged in or plans to be engaged in sexual behavior. Purpose
Reproductive System: Includes body parts involved in starting a pregnancy. Egg and sperm can join through vaginal sex, donation of sperm or with the help of medical technology. Sexual Response System: Includes body parts involved in sexual feelings. Includes physical response that happen during sexual activity with another person, or during masterbation. What is Reproduction?
Process by which a single cells duplicates its genetic material Reproduction is the process by which our genetic material is passed on from one generation to the next Requires two special cells: sperm from the male, egg from the female These cells join in the process of fertilization to produce afertilized egg, or zygote. The purpose of this system is to produce offspring and ensure the perpetuation of the human species. Male reproductive System Do you know the parts?
Male: Cowpers Gland, Epididymis, Penis, Prostate Gland, Scrotum, Seminal Vesicles, Testicle, Urethra, Vas Deferens
Female: Cervix, Glans of Clitrois, Fallopian Tubes, Fimbria, Ovary, Shaft of Clitoris, Uterus, Vagina 1. Testicles (Two)
Male Gonads Primary Male Sex Organ Produce sperm and male sex hormones Made up of 500-1200 feet of tightly coiled tubes Found in the scrotum 2. Scrotum (One)
Sac-like structure which hold the testes Regulates the temperature of the testes for sperm production 3. Epididymis
Structure that rests on top of the testes 18-20 feet of coiled tubing for storage of mature sperm 4. Vas Deferens (Two)
Long tubes that sperm travel through In the vas deferens, sperm pass by different glands that add liquids. The combination of liquid and sperm is called semen. 5. SEMINAL VESICLE (Two)
Glands that add seminal fluid Approximately 2 inches in length Produce about 60% of the volume of semen 6. PROSTATE GLAND (One)
Single, donut-shaped gland about the size and shape of achestnut Secretes a fluid that plays arole in activating sperm cells to swim About 13-33% of the fluid that makes up semen 7. COWPERS GLAND (Two)
About the size of peas Secrete thick mucus Functions as both a lubricant during sexual intercourse (pre-ejaculate) and as an agent to clean the urethra of any traces of acidic urine 8. URETHRA
Tube which carries urine from the bladder to the outside of the body In the male, this tube also carries semen from the vas deferens to the outside of the body 9. PENIS
The external structure, which is made up of three adjoining tubes that contain sponge like tissue. During sexual arousal blood flows into this tissue causing the penis to become still and erect. As puberty may happen at different times for males, the penis may reach its full size at age 13 or keep growing until age 18. FEMALE REPRODUCTIVE SYSTEM 1. OVARY
Primary Sex Organs of the Female Reproductive System AKA, Female Gonads Paired glands about the size of unshelled almonds Produce female reproductive cells called Ova (Ovum singular) Produce female sex hormones: Estrogen and Progesterone 2. FIMBRIA
Finger-like structures that guide the ovum into the fallopian tubes 3. FALLOPIAN TUBES
Tubes which extend from each ovary to the uterus Are about 3-4 inches long This is where fertilization takes place 4. UTERUS
About the size of a closed fist Where the fertilized egg is implanted, the fetus develops during pregnancy and where labor begins during delivery Shaped like an inverted pear and can greatly increase in size during pregnancy to accommodate the fetus 5. CERVIX
A cylinder-shaped tissue that connects the vagina and uterus Called the neck of the uterus Normally has a small opening into the vagina, but during childbirth this dilates from 0-10 cms 6. VAGINA
Passageway between the uterus and the outside of the body It is 3-4 inches long Menstrual fluid flows out of it during the menstruation Referred to as the birth canal the passage for babies 7. Glans of the clitoris, 8. SHAFT OF CLITORIS
Provides sensation, has two parts: the shaft and the glans Shaft is inside the body Glans is outside, making it part of the genitals The glans is in front of the openings of the urethra and vagina Eggs in a lifetime
During fetal life, there are about 6 million to 7 million eggs. From this time, no new eggs are produced. At birth, there are approximately 1 million eggs; and by the time of puberty, only about 300,000 remain. Of these, only 300 - 400 will be ovulated during awomans reproductive lifetime. Sexual response System
Now were going to talk about human sexual response. Genitals are only one part of the sexual response system. It also includes emotions, the brain, hormones, the senses and the entire body. Three important aspects of sexual response are desire, arousal and release.
Desire is the feeling of wanting to be sexually close to someone.
Arousal is the experience of being sexually excited.
Release is a reduction of sexual tension that can happen gradually over time, or more immediately during an orgasm. HOMEWORK
Choose one of two assignments. Individual Or Family Due: Review - What do the ovaries and testicles have in common?
Produce sex cells (sperm and egg); produce sex hormones (estrogen and testosterone) .Review - What do the sperm and egg have in common?
They are both sex cells and are both needed for people to reproduce. Review - What do the fallopian tubes and vas deferens have in common?
They are the pathways for the egg and for the sperm.
They both have a shaft and glans, become erect, and are the most sensitive part of the genitals.
