(c) Hymen and clitoris
(d) Uterus and vagina
(e) Efferent duct and sperm duct
Solution:-
(a)
| Menarche | Menopause |
| Menarche is the beginning of menstruation in a young girl around the age of thirteen. | Menopause is defined as the permanent stoppage of menstruation in females after the age of 45. |
(b)
| Cowper’s gland | Prostate gland |
| Cowper’s gland is a lubricating gland that opens into the urethra in human males. | A bilobed structure that covers the urethra near the bladder’s origin. As the sperm passes through the urethra, it secretes an alkaline fluid. |
(c)
| Hymen | Clitoris |
| A membrane called the hymen partially closes the opening of the vagina in young girls. | A tiny erectile clitoris is placed on the topmost angle of the vulva in front of the urethral entrance. |
(d)
| Uterus | Vagina |
| The uterus is a hollow pear-shaped muscle organ located between the urinary bladder and the rectum in the cavity between them. | The vagina is a muscular tube that runs from the uterus’s lower end to the outside. |
(e)
| Efferent duct | Sperm duct |
| The epididymis fits like a cap on the upper pole of the testis, and the efferent duct joins a little tubular knot. | The epididymis continues along the side of the testis all the way to the back, where a separate tubular sperm duct (vas deferens) emerges. |
