The Reproductive System Welcome to your The Reproductive System 1. If the vas deferens of a man are surgically disconnected or removed Spermatogenesis will not take place Semen will be without sperms Sperms in semen will be non-motile Sperms in the semen will be without nuclei2. In human males, the testes lie in the scrotum because it helps in the Formation of sperms Easy transfer of gametes Process of mating Secretion of oestrogen3. Sterilization in the female involves cutting and tying the Ureter Uterus Urethra Oviduct4. Semen is the mixture of sperms and secretions from Seminal vesicles Cowper's glands Prostate gland All of these5. Which one of the following is the route that a sperm follows when it leaves the testes of a mammal? Epididymis→Vas deferens→urethra Urethra→epididymis→Vas deferens Vas deferens→epididymis→urethra Epididymis→urethra→Vas deferens6. The site of maturation of human sperms is the Interstitial cells Epididymis Prostate gland Seminiferous tubule7. The middle piece of the sperm provides Gene Chromosomes Energy Food8. When pregnancy does not occur the life of the corpus luteum is about 28 days 14 days 10 days 4 days9. Fertilization means The fusion of nuclei of male and female gametes The meeting of male and female gametes The shedding of gametes from a reproductive organ The transfer of male gamete to the female gamete10. What will happen if the temperature of the scrotal sacs temporarily goes to about 2°C lower than normal temperature? Sperm formation will be stopped Scrotal sacs will contract and come close to the body Scrotal sacs will relax and do down away from the body Testes will start rotation movement11. The onset of menstruation in the female is termed as Menopause Ovulation Parthenogenesis Menarche12. Leydig cells produce Semen Progesterone Testosterone Oestrogen13. Corpus luteum in mammals is present in Heart and initiates atrial contraction Ovaries and produces progesterone hormone Skin and acts as a pain receptor Brain and connects the two cerebral hemispheres14. The stoppage of menstruation in the female is termed as Menopause Parthenogenesis Menarche Ovulation15. In females, after how much time after fertilization does the fertilized egg get implanted in the uterine wall? Three weeks Few months About seven days One month16. The normal gestation period in humans is 290 days 285 days 280 days 270 days17. Ovulation in mammals is a process in which The unfertilized egg passes out of female's body The egg is released from Graafian follicle The egg is fertilized in fallopian tube The egg passes through fimbriated funnel of fallopian tube18. In human beings, the fertilization occurs in the Fallopian tubes Ovaries Vagina Uterus19. The fixing of the blastocyst to the wall of the uterus or endometrium is called Implantation Gestation Parturition Fertilization20. The embryo in humans gets nutrition from the mother with the help of a special tissue called Uterus Villi Womb Placenta21 out of 20Please fill in the comment box below.
