Urethra drains urine from bladder to outside of body/ Urethra is longer in males(where it is also used to conduct semen) than in females.…
The reproductive system in the male is closely intertwined with the urinary system, both functionally and anatomically. The male reproductive system is so closely linked with the urinary tract, that urinary health is important for optimum sexual health in the male. When the prostrate is enlarged it can cause a urinary bladder infection in males.…
a. B c. d. In females the urethra joins with the vagina internally before exiting the body. In males, semen and urine are transported through the urethra. In females, the urethra empties directly into the uterus. There is no direct contact between the urinary and reproductive tracts.…
What effect would surgical removal of the seminal vesicles have on the human male reproductive system? a. It would cause sterility because sperm would not be produced. b. It would cause sterility because sperm would not be able to exit the body. c. The failure rate for the withdrawal method of birth control would go down. d. There would be a minimal loss in semen volume. e. Semen would not contain energy-providing nutrients for the sperm. 9. In humans, the egg is released from the ovary and enters the oviduct. How is this accomplished? a. The force of the follicular ejection propels the egg into the oviduct. b. The egg is drawn into the oviduct by the action of beating cilia located in the opening of the oviduct. c. The egg moves through a small tube that connects the ovary and the oviduct. d. The egg propels itself into the oviduct by the beating action of its flagellum. e. Peristalsis of ovarian muscles moves the egg into the oviduct. 10. What is the narrow opening of the human uterus called? a. vagina b. cervix c. oviduct d. fallopian tube e. vas deferens 11. Which cells are diploid? a. spermatids b. spermatogonia c. mature sperm cells d. A and B only e. A, B, and C 12. Which of these best describes the menstrual cycle? a. It refers specifically to changes that occur in the endometrium of the uterus. b. The cycle length is 28 days and varies little from one woman to another. c. It continues from puberty until death. d. It begins with the follicular phase. e. It is primarily regulated by follicle-stimulating hormone (FSH). 13. What are the three phases of the ovarian cycle? a. menstrual, ovulation, and luteal b. follicular, luteal, and secretory c. menstrual, proliferative, and secretory d. follicular, ovulation, and luteal e. proliferative, luteal, and ovulation 14. Inhibition of the release of GnRH from the hypothalamus will a. stimulate production of estrogen and progesterone. b. initiate ovulation. c. inhibit secretion of gonadotropins from the pituitary.…
| The route of sperm from the production in the testes to the exterior of the body is: seminiferous tubules, straight tubules, rete testes, epididymis, ductus (vas) deferens, ejaculatory duct, prostatic urethra, membranous urethra, spongy urethra, external urethral orifice.…
Then the eggs that are not fertilized become eggs that most people see on their plates. We see pair of dogs and it explains that the male dog has two scrota, and “a tube called a penis”(46) , the penis is what is used during reproduction. The male mounts the female and releases his sperm. Then the egg is fertilized and in eight to nine weeks a puppy is born. The female produces milk in her mammary glands and feeds the puppies. Then finally we see how two humans have a baby. The woman has ovaries and every 28 days an egg is realized travels down its fallopian tube. The man has sperm in his penis and with the penis he enters the woman’s vagina and then the man releases his sperm into the vagina. Then the egg is fertilized and travels down into the woman’s uterus. Then in a couple of weeks the baby starts to form and then after nine months a child is born. The females body helps deliver the baby through the vagina. Then the umbilical cord is removed. Just like the puppies the child receives milk from the mothers mammary glands and it receives milk. Then this showed how…
Relationships can be explained by both sexual selection and the human reproductive system; however they both differ from each other. Sexual selection explains how evolution is driven by competitions for mating and to ensure the characteristics that are chose allow the reproduction to be a success. The human reproductive behaviour explains the strategies that both males and females take on. Sexual selection has two types, Intra-sexual selection and Inter- sexual selection. Intra-sexual selection is men competing towards each other for females. This allowed men to evolve into bigger, stronger males with more manly characteristics. Inter-sexual selection involves females choosing their males. They seek partners who can provide them with resources such as a home and wealth as well as protection. Due to the two types of selection, both male and females have evolved leading to better characteristics.…
When the U.S. population had reached a record, the 300 millionth person to be born, news reports and the media started to clamor. How with the “major” help of the Latinas did this come to happen (Chavez 70)? It is evident that we need to look deeper into how this data is represented in the U.S. and realize that these representations are not always accurate. A myth is more than a made up story, it can be the topic of what we represent to believe true. “Latina sexuality, fertility, and reproduction are analyzed as key intertwined concepts in a national public discourse on immigration (Chavez 73).” This story is way more convoluted than we are told to accept as true. In general, it may be true that…
The aim of the female reproductive system is to produce mature oocytes which match with the male spermatocyte to create offspring. Fertilisation most commonly occurs in the fallopian tubes, though this can also occur later in a female’s menstrual cycle if the egg has already moved down into the uterus, though there is a higher chance of miscarriage as the lining of the womb may continue to shed. The external female reproduction features have two functions; to allow insemination and to also protect against infection and injury. These structures include; the labia majora, which contains glands that produce sweat, the labia minora which surrounds the opening of the vagina and urethra, bartholin's glands which are just behind the vaginal…
The ovum cell is one of the most important cells in all living organisms. Most ova are unicellular because they are only one cell at first but becomes multi cellular once fertilized by the sperm and begin dividing. However, in other organisms, such as protists, they can start off as multi cellular as well. The ova is the female gamete produced by the female reproductive system and joins together with the sperm, the male gamete, during fertilization to form the embryo. Gametes are haploids which is the only type of cell that contains only one set of chromosomes. Ova are produced by many living organisms, such as animals, protists, fungi, and flowering plants and ferns. In animals, they are produced…
To complete this process, an egg cell needs a genetic code to create a new life which is carried by the sperm cell. If a male and a female had a sexual intercourse, the sperm from the male will be delivered to the female’s reproductive system which is called the cervix. From the cervix, only a few sperm cells will make it through and they will travel and race to reach the egg cell of the female. Once the sperm cells reached to the egg cell, they will penetrate through the egg cell but only one will make it. And if the sperm penetrates the egg cell, it seals it and the other remaining cells outside dies.…
The critical point in a developing fetus falls roughly within the 5th week and the 6th month. This period is defined as the critical period because beginning around the 5th week tissue begins to differentiate. This specialized tissue starts developing from the top down. Specialized tissues begin forming limbs and digits from the top of the fetus and working its way down to its limbs.…
For the male reproductive system there are two major parts: testes, where the sperm is produced and the penis. In males the penis and urethra belong to both the urinary system and reproductive system. The testes are carried in an external pouch that is more commonly known as the scrotum. They actually remain at a slightly cooler temperature than normal body temperature so that they are able to facilitate sperm production. 1…
Pregnancy is the result of male and female intercourse or due to artificial insemination, which then conception occurs.…
