Which of the following role/roles is/are played by epididymis, vas deferens, vas deferens and prostate gland in the male reproductive system of human?
(A) spermatogenesis and motility of sperms
(B) maturation and motility of sperms
(C) spermatogenesis and maturation of sperms
(D) sperm motility only
Detailed Solution. Maturation of sperms occurs in Epididymis, while the vas deferens help in the motility of sperms. Two glands storing and producing the fluid that makes up the semen are called the seminal vesicles. The fluid from the seminal vesicles gets expelled to the ejaculatory duct during ejaculation.
Which one of the following is not a component of the human male reproductive system?
(A) Seminal Vesicle
(B) Uterus (Cervix)
(C) Urethra
(D) Vas Deferens
The correct answer is Cervix. Cervix is not a component of the human male reproductive system. Cervix facilitates the passage of sperm into the uterine cavity.
When the gamete cells of two individuals combine during sexual reproduction, they form
(A) Fetus
(B) Endosperm
(C) Zygote
(D) Egg
During sexual reproduction, two haploid gametes combine into one diploid cell known as a zygote in a process called fertilization. The nuclei from the gametes fuse, and each gamete contributes half of the genetic material of the zygote.
The development of the child inside the mother's body (in the case of humans) takes about a month.
(A) 10
(B) 9
(C) 7
(D) 8
The development of the child inside the mother's body takes approximately eleven months.
Which one of the following is a specific type of milk that is produced in a lactating mother and is essential for the development of an immune response in a human newborn?
(A) Transitional Milk
(B) Skimmed Milk
(C) Neonatal (Colostrum)
(D) Milk produced in breast one month after the birth of the baby
Colostrum is the first form of breastmilk that is released by the mammary glands after giving birth. It's nutrient-dense and high in antibodies and antioxidants to build a newborn baby's immune system. It changes to breast milk within two to four days after your baby is born.
Which of the following is not a part of the female reproductive system?
(A) Vagina
(B) Vas Deferens
(C) Uterus
(D) Ovaries
Vas deferens is not a part of the female reproductive system as it is the duct that is meant to carry sperms. It belongs to the male reproductive system. Ovary, Uterus, Fallopian tubes are the parts of the female reproductive system in human beings.
In which part of the male reproductive system is the main genetic material found?
(A) in the prostate gland
(B) in the ureter
(C) in sperm
(D) in the testicles
The sperm. The sperm is the male reproductive cell. Its role is to fertilise an egg. It contains the man's genetic material.
Which hormone causes milk to be released from the breast during lactation?
(A) Estrogen
(B) Prolactin
(C) Oxytocin
(D) Progesterone
Prolactin is necessary for the secretion of milk by the cells of the alveoli. The level of prolactin in the blood increases markedly during pregnancy, and stimulates the growth and development of the mammary tissue, in preparation for the production of milk (19).
Where does the process of fertilization take place in the human body?
(A) Fallopian Tubes
(B) Ovaries
(C) Uterus
(D) Vagina
In natural conception, the male sperm fertilizes the female egg inside the woman's body. While many think fertilization occurs in the ovary, it actually takes place in the fallopian tube just outside the ovary.
The upper part of the respiratory tract is provided with small hair-like structures called ______.
(A) bronchi
(B) cilia
(C) villi
(D) alveoli
