The Sperm and the Egg
Trace the movements of the sperm and the egg from their development to fertilization.
While a man (John) and women (Nancy) comment the act of sexual affairs, the women has to be in a productive state and her body will discharge one egg for the sperm to residence. John will discharge anywhere from 100 million to 300 million sperms in one conference of intercourse, His sperm must first make their way thru the cervix into the uterus then on to the fallopian tube, the liquid portion of the semen not only provide the sperm but is also use as a nourishment for the journey into the and ...view middle of the document...
This process happen in 5-7 days it moves into the uterus and it becomes the embryo. The rudiment implants itself and burrows into the endometrial. This is the pregnancy state. The Embryo develops in the fallopian tube for about 3 days then travel into the uterus and it goes thru the states of blastocyst. Nancy has now reached implantation.
Describe the function of each of the male and female internal and external sex organs in relation to the sperm and the egg.
The female reproductive system is intended to carry out numerous functions. It produces the female egg cells essential for reproduction, called the ova or oocytes. The structure is designed to transport the ova to the site of fertilization. Conception, the fertilization of an egg by a sperm, generally occurs in the fallopian tubes. The next step for the fertilized egg is to implant into the walls of the uterus, beginning the initial stages of pregnancy. If fertilization and/or implantation don’t take place, the system is designed to menstruate (the monthly shedding of the uterine lining). In addition, the female reproductive system produces female sex hormones that maintain the reproductive cycle.
The purpose of the external female reproductive structures the genitals is twofold: To facilitate sperm to penetrate the body and to defend the internal genital organs from infectious organisms. The main external structures of the female reproductive system include. Labia majora: The labia majora surround and protect the other external reproductive organs. Literally translated as "large lips," the labia majora are relatively large and fleshy, and are comparable to the scrotum in males. The labia majora contain sweat and oil-secreting glands. After puberty, the labia majora are covered with hair. Bartholin's glands: These glands are located besides the vaginal cavity and produce a fluid (mucus) secretion.Clitoris: The two labia minora meet at the clitoris, a small, thin-skinned protuberance that is comparable to the penis in males. The clitoris is sheltered by a fold of skin, called the prepuce, which is similar to the foreskin at the end of the penis. Like the penis, the clitoris is very sensitive to stimulation and can become erect. The internal reproductive organs in the female include: Vagina: The vagina is a passage that joins the cervix (the lower part of uterus) to the exterior of the body. It also is known as the birth canal. Uterus (womb): The uterus is a hollow, pear-shaped organ that is the home to a developing fetus. The uterus is separated into two parts: the cervix, which is the lower part that opens into the vagina, and the main body of the uterus, called the corpus. The corpus can easily expand to hold a developing baby. A direct through the cervix allows sperm to enter and menstrual blood to exit. Ovaries: The ovaries are miniature, oval-shaped glands that are positioned on either side of the uterus. The ovaries produce eggs and hormones. Fallopian tubes: These are slender...
