Answer
a. **Penis:** The penis is the male organ for sexual intercourse. It delivers sperm into the female reproductive tract. The erectile tissue within the penis allows it to become engorged with blood, enabling penetration of the vagina.b. **Uterus:** The uterus is a hollow, muscular organ in the female pelvis where a fertilized egg implants and develops into a fetus. It provides nourishment and protection for the developing fetus throughout pregnancy.c. **Ovaries:** The ovaries are the female gonads. They produce and release eggs (ova) and female sex hormones, such as estrogen and progesterone, which are essential for reproduction and the development of secondary sexual characteristics.d. **Vagina:** The vagina is a muscular canal that connects the external genitalia to the cervix. It serves as the birth canal during childbirth and receives the penis during sexual intercourse. It is also the passageway for menstrual flow.e. **Cervix:** The cervix is the lower, narrow part of the uterus that opens into the vagina. It acts as a gateway between the vagina and the uterus. During pregnancy, the cervix remains closed to protect the developing fetus. It dilates during labor to allow the baby to pass through.f. **Oviducts/Fallopian tubes:** These tubes extend from the ovaries to the uterus. They are the site where fertilization typically occurs. The oviducts transport the egg from the ovary to the uterus, and they also transport sperm towards the egg.g. **Seminiferous tubules:** Located within the testes, the seminiferous tubules are the specific location of sperm production (spermatogenesis).h. **Prostate gland:** The prostate gland is a male reproductive gland that produces a fluid component of semen. This fluid nourishes and protects sperm.i. **Scrotum:** The scrotum is a sac of skin that hangs outside the male body and contains the testes. It regulates the temperature of the testes, keeping them slightly cooler than body temperature, which is essential for sperm production.
