Hint: The external anatomy of the female system is referred to as the vulva; it includes labium, which protects vagina, urethra, and the labium surrounds it. Internal female reproductive structures include ovaries, oviducts, the uterus as well.
Female reproductive anatomy includes both external and internal structures. Among the external structures are the vulva, which consists of the fatty tissue, clitoris, labium, labium, and therefore the vestibular glands. The vulva is a district related to the vestibule that has the structures found within the inguinal (groin) area of ladies. Clitoris contains an outsized number of sensory nerves and is a source of stimulation during intercourse. The labium are a pair of elongated folds of tissue that run posterior from the adipose tissue and enclose the opposite components of the vulva. The labium derives from the identical tissue that produces the scrotum during a male. The labium are thin folds of tissue centrally located within the labium. These labia protect the openings to the vagina and urethra. The fat and also the anterior portion of the labium become covered with hair during adolescence; the labium is hairless. The greater vestibular glands are found at the perimeters of the vaginal opening and supply lubrication during intercourse.
Internal female reproductive structures include ovaries, oviducts, the uterus, and therefore the vagina. An ovary consists of a medulla and cortex: the medulla contains nerves and blood vessels to provide the cortex with nutrients and take away waste. Cortex is formed of follicular cells surrounding the eggs. During the cycle, a batch of follicular cells develops, preparing the eggs for release. At ovulation, one follicle ruptures and one egg is released.
The oviducts, or fallopian tubes, extend from the uterus within the lower cavum to the ovaries, but they're not involved with the ovaries. The lateral ends of the oviducts widen into a trumpet-like structure and have a fringe of finger-like projections called fimbriae. When an egg is released at ovulation, the fimbriae help the non-motile egg enter into the tube, the passage to the uterus. The walls of the oviducts are ciliated (covered in cilia) and are primarily smooth muscle. The cilia beat toward the center, while the sleek muscle contracts within the same direction, moving the egg toward the uterus.
Fertilization usually takes place within the oviducts. The embryo is moved toward the uterus for further development. It always takes the egg or embryo per week to travel through the oviduct.
The uterus is lined with an endometrium rich in blood vessels and mucus glands. It supports developing embryos and fetuses during gestation. The thickest portion of the wall of the uterus is created of smooth muscle. Contractions of the sleek muscle within the uterus aid in passing the baby through the vagina during labor. A little of the liner of the uterus sloughs off during each menstrual period if an egg has not been fertilized; it builds up again in preparation for an implantation. A part of the uterus, called the cervix, protrudes into the highest part of the vagina, which functions because of the passage.
The vagina also allows menstrual blood to depart the body, is that the receptacle for the penis during intercourse, and is the vessel for the delivery of offspring. It's lined by stratified squamous epithelial cells to guard the underlying tissue.
Hence, the correct answer is option (D)
Note: Common mistakes and misconceptions:
1.Fertilization occurs within the Fallopian tube (oviduct) of the feminine system. Once fertilized, the egg attaches to the liner of the uterus. It becomes a ball of cells over time, then develops within the uterus of the feminine to become a baby.
2.Only females are born with reproductive sex cells. Females are born with immature eggs already in their ovaries. When puberty occurs, the eggs mature and are released by the ovaries. Males only produce sperm after reaching puberty
