Which Statement Describes The Reproductive System Of The Human Male? A. It Releases Sperm That Can Be - Brainly.Com

Testes||External||Produce sperm and male hormones|. The human male and female reproductive cycles are both controlled by the interaction of hormones from the hypothalamus and anterior pituitary with hormones from reproductive tissues and organs: the hypothalamus sends a gonadotropin-releasing hormone (GnRH) to the anterior pituitary, and follicle stimulating hormone (FSH) and luteinizing hormone (LH) are release from the anterior pituitary into the blood as a result. We'll first look at females, followed by males, emphasizing the structures, the process of gametogenesis, and hormonal control of reproduction. In land mammals, the pair of testes must be suspended outside the body at about 2° C lower than body temperature to produce viable sperm. C. the secretion of estrogen by the ovary. The male reproductive system: - makes semen (SEE-mun). The brain and the nervous system give the scrotum the cue to change size. Which of the following answer choices correctly describes the path of a mature sperm, during normal male ejaculation? In the human reproductive process, two kinds of sex cells, or gametes (GAH-meetz), are involved. The sperm cell production is mediated by two different types of cells: "nursemaid" cells called Sertoli cells which protect the germ cells and promote their development, and cells of Leydig which produce high levels of testosterone once the male reaches adolescence and regulate sperm development. Facial hair develops, as well as hair on the chest, abdomen, and limbs. Women and girls often face greater barriers than men and boys to accessing health information and services. Are immobile when kept at body temperature; therefore, the scrotum and penis are external to the body, as illustrated below, so that a proper temperature is maintained for motility.

Which Statement Describes The Reproductive System Of A Human Male Reproductive

The importance of the scrotum is to regulate temperature because sperm synthesis in the testes must occur at a few degrees below body temperature. A negative feedback system occurs in the male when sperm counts get too high (over about 20 million/ml): rising testosterone levels cause Sertoli cells to release the hormone inhibin, which acts on the hypothalamus and pituitary gland to inhibit the release of FSH and LH. If semen is ejaculated into a female's vagina, millions of sperm "swim" up from the vagina through the cervix and uterus to meet the egg in the fallopian tube. This process prepares the egg for ovulation. Gender inequality hinders progress to fulfill everyone's right to health. Rate of production: Once an individual enters puberty, sperm production is continuous in a "conveyor belt" process; egg production occurs one-at-a-time at each menstrual cycle. Next, the penis becomes longer and the seminal vesicles and prostate gland grow. The Human Female Reproductive System: The female reproductive system is largely internal. The oocyes remain in meiotic prophase I until the onset of puberty, when a series of events can lead to egg maturation: - The anterior pituitary hormones, FSH and LH, cause some of the follicles to begin developing and oocyte inside the follicle to finish the first meiotic division. Addressing discrimination against women and girls is critical to achieving UHC. The cells divide and change until they have a head and short tail, like tadpoles. Temperature regulation. Oogenesis, the process of producing an egg cell, occurs in the the ovaries. The female reproductive system primarily consists of internal organs.

This is most damaging early in a pregnancy because during this time. Once fertilized, an ovum becomes a zygote and if all goes well, develops into a fetus in the uterus. Penis: The male sexual organ for copulation and urination; the tubular portion of the male genitalia (excluding the scrotum). When sperm fertilizes (meets) an egg, this fertilized egg is called a zygote (ZYE-goat). Consequently, they are at higher risk of HIV and mental health problems, including suicide. How Does the Male Reproductive System Work?

CC LICENSED CONTENT, SHARED PREVIOUSLY. Just like oogenesis, spermatogenesis is controlled by FSH, LH. During this process, the erect penis of the male is inserted into the female's vagina until the male ejaculates semen, which contains sperm, into the vagina. The cells of Leydig (also known as the interstitial cells) secrete testosterone and other androgens (male sex hormones), while the Sertoli cells are responsible for nourishing developing sperm. Learn about fetal genital development. A woman's body temperature may rise a degree Celsius at ovulation and the cervical mucus may increase in volume and become more pliable. The scrotum is responsible for which of the following in the male repoductive system? The bulk of the semen comes from the accessory glands associated with the male reproductive system. Curation and Revision. In the male reproductive tract, sperm cells follow a specific path. While this doesn't occur in a monthly cycle as in females, the hormones do interact in a feedback cycle which initiates during puberty: In response to signals from the hypothalamus that begin at the onset of puberty in males, the pituitary gland produces FSH.

05 millimeters long). The endometrium begins to degenerate as the progesterone levels drop, initiating the next menstrual cycle. The sex of a child is determined at the time of fertilization of the ovum by the spermatozoon. The most reliable method, with a failure rate of less than 1 percent, is the implantation of the hormone under the skin. WHO also supports country-level action to strengthen health sector response to gender-based violence, as well as to address gender equality in health workforce development and gender-related barriers to health services. LICENSES AND ATTRIBUTIONS. The gland is a mixture of smooth muscle and glandular tissue. For a detailed discussion of the series of changes that occur in a woman's body as her fetus develops, see pregnancy. Withdrawal involves the removal of the penis from the vagina during intercourse, before ejaculation occurs. Summarize the reproductive systems of men and women.

Eggs are large cells that require a substantial investment of time and energy to form, are non-mobile, and are rare relative to sperm numbers. Contraception and Birth Control. The second category, the ejaculatory fluid-producing glands, includes the seminal vesicles, prostate, and vas deferens. During a vasectomy, a section of the vas deferens is removed, preventing sperm from being passed out of the body during ejaculation and preventing fertilization. During the menstrual cycle, a batch of follicular cells develops and prepares the eggs for release.

What is the human embryo called after the eighth week of development? Women and girls also face unacceptably high levels of violence rooted in gender inequality and are at grave risk of harmful practices such as female genital mutilation, and child, early and forced marriage. Ovulation occurs just prior to the middle of the cycle (approximately day 14), when the high level of estrogen produced by the developing follicles causes FSH and especially LH to rise rapidly, then fall. If an ovum is currently in the uterus, it can then be fertilized by sperm that manage to enter the cervix.

This may be an evolutionary adaptation to expel the semen left by other males while at the same time increasing the possibility of fertilization with the current male's semen. B. alcohol can easily enter the mouth of the fetus. One important type of parental care is the use of the mammary glands in the female breasts to nurse the baby. The oviducts, or fallopian tubes, extend from the uterus to the ovaries, but they are not in direct physical contact with the ovaries. As you've just seen in the two videos the production of sperm and eggs takes place through the process of meiosis, but there are some big differences between the processes to make eggs versus sperm: - When gametes start to form: Egg production begins during embryonic development (before birth), then is arrested during meiosis until puberty; sperm production does not begin until puberty.

Human babies and children are nearly helpless and require high levels of parental care for many years. When ejaculation occurs, sperm is forcefully expelled from the tail of the epididymis into the deferent duct. Because of this, be sure to know all steps of a pathway, not just the beginning or end. It is also the hormone responsible for the secondary sexual characteristics that develop in the male during adolescence, including a deepening of the voice, the growth of facial, axillary, and pubic hair, and the beginnings of the sex drive.

Ovaries||Produces and develops eggs|. These include the breasts and the vulva.

D. sperm and egg production.
