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
