OBJECTIVE
SC.912.L.16.13*-
Describe the basic anatomy and physiology of the human reproductive system.
I will Identify and describe the basic anatomy and physiology of the human reproductive system for both males and females.

3. WHAT IS THE ESSENTIAL QUESTION?
Identify and describe the basic anatomy (body parts) and physiology (their functions) of the human reproductive system for both females and males.
Words to know:
Female: ovaries, oviducts (aka fallopian tubes), uterus, cervix, vagina.
Male: seminal vesicle, prostate gland, vas deferens, urethra, epididymis, scrotum, penis, testis.

4. What are the main functions of the female reproductive system?
The organs of the female reproductive system are specialized for Four major functions:
To enable sperm to enter the body, to meet with and fertilize the egg, and create a new living thing.
The location where a baby develops.
To protect the internal genital organs from infectious organisms.
To produce and secrete female sex hormones.

5. “HI, I’M MARY! C’MON IN AND TAKE A LOOK!”
Egg/Ova
23 chromosomes Haploid
The female reproductive
system produces ova, or eggs, the female reproductive cell, or gamete.
The ova are produced by female gonads (sexual glands) called ovaries. All of the eggs are present when a female is born.

6. HOW DOES THE OVA TRAVEL INSIDE OF THE FEMALE BODY?
The fallopian tubes or Oviducts allows the egg to travel from the ovary to the uterus.
The uterus, or womb, is the
major female reproductive
organ where the fetus develops during gestation, also called pregnancy.

7. HOW DOES THE OVA TRAVEL INSIDE OF THE BODY?
The cervix is the lower, narrow portion of the uterus where it joins with the top end of the vagina.
The cervix has a very tiny opening to allow sperm and menstrual fluid to move through. It must dilate to 10 cm during birth.
The vagina is a hollow muscular organ that joins the cervix (the lower part of uterus) to the outside of the body. The vaginal walls are lined with mucus membranes for protection and to keep it moist. This is where sexual intercourse occurs and the canal through which a baby is born.

8. What are the main functions of the male reproductive system?
The organs of the male reproductive system are specialized for three major functions:
To produce, maintain, and transport sperm (the male reproductive cells) and the protective fluid called semen that the sperm travel in.
To discharge sperm into the female reproductive tract.
To produce and secrete male sex hormones.

9. Male “Sperm” refers to the male reproductive cells or gamete.
DNA
23 Chromosomes
Haploid
“Sperm” refers to the male reproductive cells or gamete.
The scrotum is a pouch-like structure containing numerous nerves and blood vessels, and hangs behind the penis. It holds and protects both of the testicles.
The testes are the male gonads. They produce both sperm and the very important male sex hormone testosterone.
The scrotum is outside the body bc the sperm need to be kept at a lower temperature than the bodies normal temperature.**
Mammalian sperm cell consists of a head, a
midpiece, and a tail.

10. HOW DOES THE SPERM TRAVEL INSIDE, THEN OUT OF THE BODY?
The epididymis is a mass of tightly coiled tubes cupped against each of the testicles. It is the place where sperm mature and are stored.
When sperm leave the testicles through the epididymis, they then pass through the vas deferens, a tube that carries the sperm passed the seminal vesicles and then to the prostate gland to produce semen.
Coiled epididymis-increases area to hold more.*
The vas deferens, also known as the sperm duct, is a thin tube approximately 43.2 centimetres long that starts from the epididymis to the pelvic cavity.

11. HOW DOES THE SPERM TRAVEL INSIDE, THEN OUT OF THE BODY?
The seminal vesicles are a pair of sac-like structures attached to the vas deferens located on either side of the bladder, toward the back. They produce a fluid called seminal fluid (NOT semen) which provides energy to the sperm and is excreted into the prostate gland.
The prostate gland is located just below the bladder, surrounding the urethra. It is responsible for the production of semen, which is a mixture of sperm cells, seminal fluid, and fluid from the prostate. The semen passes from the prostate to the urethra and out of the penis.
The vas deferens, also known as the sperm duct, is a thin tube approximately 43.2 centimetres long that starts from the epididymis to the pelvic cavity.

12. HOW DOES THE SPERM TRAVEL OUT OF THE BODY?
The urethra is a tube that connects the urinary bladder and the prostate gland to the penis for the removal of urine from the body, as well as semen. Semen and urine are prevented from mixing during ejaculation.
The penis is the way in which males release both sperm and urine from the body. The penis is also used to deliver the sperm to the female vagina.
The vas deferens, also known as the sperm duct, is a thin tube approximately 43.2 centimetres long that starts from the epididymis to the pelvic cavity.
