They both allow internal fertilization to occur.

The female and male reproductive systems have distinct structures that are tailored to their specific functions.

Female Reproductive System:
The female reproductive system consists of organs such as the ovaries, fallopian tubes, uterus, cervix, and . Their structures are designed to support fertilization, pregnancy, and childbirth.

Ovaries: The ovaries produce eggs (ova) and release them into the fallopian tubes during ovulation.

Fallopian Tubes: These tubes connect the ovaries to the uterus. They have hair-like structures called cilia, which help propel the egg toward the uterus. The fallopian tubes are the site where fertilization occurs when a sperm meets an egg.

Uterus: The uterus is a muscular organ where a fertilized egg implants and develops into a fetus during pregnancy. The inner lining of the uterus, called the endometrium, undergoes monthly changes in preparation for a potential pregnancy.

Cervix: The cervix forms the lower part of the uterus and connects it to the . It plays a role in supporting pregnancy and also acts as a protective barrier, preventing infections from entering the uterus.

: The serves as the birth canal during childbirth and also provides a passageway for menstrual blood and sperm.

Male Reproductive System:
The male reproductive system includes organs like the testes, epididymis, vas deferens, prostate gland, seminal vesicles, urethra, and . Its structures are designed for the production, storage, and delivery of sperm.

Testes: The testes are responsible for producing sperm cells and sex hormones (such as testosterone). They are located outside the body within the scrotum, which helps regulate the temperature necessary for proper sperm production.

Epididymis: The epididymis is a coiled tube located on the back of each testicle. It acts as a storage and maturation site for sperm, allowing them to gain motility and become capable of fertilizing an egg.

Vas Deferens: The vas deferens carries mature sperm from the epididymis to the ejaculatory ducts. These tubes carry sperm towards the urethra during ejaculation.

Prostate Gland and Seminal Vesicles: These glands produce fluids that mix with sperm to form semen. The fluid from the seminal vesicles contains nutrients to nourish the sperm, while the prostate gland produces an alkaline fluid that helps protect sperm from the acidity of the .

Urethra: The urethra serves as a common passageway for both urine and semen. It extends from the urinary bladder and runs through the , allowing ejaculation to occur during sexual activity.

: The plays a crucial role in sexual reproduction by delivering sperm into the female reproductive tract during intercourse.

In summary, the structures of the female and male reproductive systems are well-suited for their functions of producing, transporting, and facilitating the meeting of eggs and sperm, as well as supporting fertilization, pregnancy, and childbirth.
