short answers about reproductive systems




Question: What are the main parts of the human male reproductive system?



Answer: The human male reproductive system comprises of the following:
1) a pair of testes, organs that produce the male gametes, sperms
2) a network of tubules and tubes for passage of the sperms called the duct system
3) associated glands
4) a mating organ called the penis




Question: Name the constituents of the duct system of the male reproductive part.


Answer: Vasa efferentia, epididymis, vas deferens, ejaculatory tube and the urethra are the constituents of the duct system of the male reproductive system.




Question: Which are the various glands associated with the male reproductive system?


Answer: The various glands associated with the male reproductive system are seminal vesicles, prostate glands and Cowper's glands.




Question: Write short notes on seminal vesicles.


Answer: Seminal vesicles A pair of seminal vesicles are glands that are present behind the urinary bladder. Each sperm duct has the seminal vesicle of its side secreting a fluid into the common ejaculatory duct. This fluid along with the sperms is called the semen, a milky fluid.


Question: What are the functions of prostate and Cowper's glands?

Answer: Prostate gland makes the semen alkaline with its secretions and Cowper's glands secretes lubricating fluid into the urethral tube.


Question: What are the different parts of the female reproductive system?



Answer: The female reproductive system consists of a pair of ovaries, a pair of oviducts, uterus, vagina and vulva.




Question: What are the functions of the female reproductive system?
Answer: The main functions of the female reproductive system are:
1) to produce eggs
2) receive the sperms
3) provide the site for fertilization
4) implantation of the growing embryo and development of the foetus
5) production of hormones that control the various stages of ovulation and maintenance of pregnancy.
Question 48



Question: What is the function of the fallopian tubes?
Answer: The fallopian tubes transport the eggs from the ovary to the uterus and also serve as the site for fertilization of the egg by sperm.
Question 49



Question: Write short notes on uterus.
Answer: Uterus is a pear-shaped structure, broader on the upper end and narrower on the lower end. The upper end is called the body of the uterus and the lower end is called the cervix. At the upper end, it receives the oviducts of either side whereas the lower end the cervix opens into the vaginal canal that opens to the outside.

The uterine wall has three layers. They are the innermost endometrium made up of several glands and blood vessels, the middle myometrium made of smooth muscles and the outer perimetrium made of connective tissue. The inner surface of the uterus provides a site for the implantation of the embryo. The uterine wall plays an important role during childbirth. Cervix is made of sphincter muscle that controls the opening and closing of the uterus.




Question: What is onset of puberty in females?
]

Answer: At about the age of 10 to 13 years, the ovaries of females are stimulated by the follicle stimulating hormone (FSH) of the pituitary. This is called the onset of puberty and is accompanied by release of hormones oestrogen and progesterone.
