and the organs involved in both Male and Female genital system.
3. Gross Anatomy and functions of the Organs involved in male genital system.
4. Gross Anatomy and functions of the Organs involved in Female genital system.
Objectives
When you finish this lesson, you should be able to
• Describe the Functions of the Male and Female Reproductive system
• Identify the Gross Anatomy and Explain the Functions of the organs involved in the Male Genital system.
• Identify the Gross Anatomy and Explain the Functions of the organs involved in the Female Genital system.
Functions of genital system
To ensure survival of the species To produce egg and sperm cells To transport and sustain these cells
Production of hormones Hormones permits the secondary sex
characteristics, such as breast development in women and beard growth in men.
GROSS ANATOMY OF GENITAL SYSTEM
Male & Female genital system
Composed of :1. Reproductive organs called gonads that
produce gametes (reproductive cells) and hormones
2. Ducts that transport gametes
3. Accessory glands and organs that secrete fluids
Male genital system
Functions– To produce, maintain and transport
sperm (the male reproductive cells) and protective fluid (semen)
– To produce and secrete male sex hormones responsible for maintaining the male reproductive system
Male genital organs
Consists of1. A pair of testes 2. A network of excretory ducts • Epididymis• Ductus deferens• Ejaculatory ducts
3. Seminal vesicles4. Prostate5. Urethra6. Penis
Male Genital system
Testes / testicles (Gonads)
Produce sperm(Spermatogenesis) Sperm production
begins at puberty and continues throughout the life of a male
Testes / testicles (Gonads)
Produce testosterone • Hair patterns and
voice changes
• Development of the male accessory organs (prostate, seminal vesicles etc.)
• Stimulates the effect of protein building in the body that is responsible for the greater muscle development and strength of the male
Male Genital system
• Duct System– Epididymis
• Sperm mature in epididymis
– Ductus Deferens• Transports
mature sperm to the urethra
– Ejaculatory ducts• empty into the
urethra
Male Genital system
Seminal vesicles– Attached to vas
deferens
– Produce a sugar rich fluid (fructose) that provides energy to sperm
Male Genital system
Prostate Gland Makes seminal fluid .
Male Genital system
UrethraTube that carries urine from the bladder to outside of
the body
Also carries semen out of the body
Male Genital system
Functions1. Produces the female egg cells
2. Transports the eggs to the site of fertilization
3. The fertilization of an egg by a sperm, occurs in the fallopian tubes
Female genital system
Functions1. After fertilization, provides a place for a baby
to develop
2. If fertilization does not take place, the system is designed to menstruate
3. Produces female sex hormones that maintain the reproductive cycle.
Female genital system
Female genital system
Consists of1. Uterus (corpus and cervix)
2. vagina
3. Ovaries
4. Fallopian tubes
Female genital system
Coronal section Sagittal section
Female genital systemUterus
– Hollow, pear-shaped organ that is the home to a developing fetus• Divided into two parts:
– the cervix, the lower part that opens into the vagina
– Main body of the uterus, called the corpus.
– The corpus can easily expand to hold a developing baby.
– A channel through the cervix allows sperm to enter and menstrual blood to exit
Female genital system
Vagina– Canal that joins the
cervix (the lower part of uterus) to the outside of the body
– Also is known as the birth canal.
Female genital system
Ovaries
– Oval-shaped glands that are located on either side of the uterus
– Produce eggs and hormones.
Female genital system
Fallopian Tubes– Narrow tubes that are
attached to the upper part of the uterus and serve as tunnels for the egg cell to travel from the ovaries to the uterus
– Fertilization of an egg by a sperm, normally occurs in the fallopian tubes
– The fertilized egg then moves to the uterus, where it implants into the lining of the uterine wall
