1. Human Anatomy

2. The Male Reproductive System  Seminal tubules: the region in which sperm is produced, contained in the testis  Epididymis: a narrow, tightly-coiled tube connecting the seminal tubules from the rear of each testical to the vas deferens

3. Male Reproductive Systems continued…  Vas deferens: transports sperm from the epididymis in anticipation of ejaculation  Seminal Vesicle: secretes the fluid that becomes semen  Prostate Gland: secrete the remainder of the fluid that becomes semen (20-30%)

4. Male Reproductive Systems continued…  Urethra: a tube that connects the bladder to the genitals for the removal of fluids. The urethra travels through the penis, and carries semen as well as urine  Scrotum: contains the testis  Penis: the external organ in which the urethra is held

6. Male reproductive information  Males begin to produce sperm at puberty  Sperm lay dormant in the seminiferous tubules of the testis since the fetal period, and begin to increase in number at puberty  The sperm then travel into the epididymis where they are held and continue to develop

7. Male reproductive information  Testosterone is the principal male sex hormone  It has the key role in developing male reproductive tissues such as testis and prostate as well as promoting secondary sex characteristics, including: hair, skin, larynx, metabolism rates, blood cells, kidney, muscle, bones

8. Female Reproductive Systems  Ovary: these are equivalent to testis in males, but produce ovum (eggs) rather than sperm  Fallopian Tube (ovarian duct): small tube that carries the egg from the ovaries to the uterus. It is ciliated (has projections on the tube), which helps move the egg forward

9. Female Reproductive Systems continued…  Uterus: this is the major sex organ for females. Fetal development occurs here  Endometrium: the inner lining of the uterus. The fertilized egg (zygote) implants itself in the endometrium. It is also the portion that is sloughed off during menstruation

10. Female Reproductive Systems continued…  Cervix: the lower, narrow portion of the uterus. It connects the vagina to the uterus through the cervical os  Vagina: tubular tract connecting the labia to the cervix. It is an internal structure, often used to refer to the labia  Labia: external lip-like structures

11. Female Reproductive Systems continued…  Urethra: shorter than in males and emerges above the vaginal opening  Clitoris: the visible button-like portion is located in front of the urethra and vagina. The penis is homologous (equivalent) to the clitoris.
