Q80) Given below is a statement with some blanks. Fill up the blanks correctly -
The male reproductive system consists of two testes. Each testis contains thin folded tubes called the __(A)__ which meiosis take place to produce the male gametes, the sperms. These sperms move to the __(B)__ ( a highly coiled tube formed from the merging of the seminiferous tubules), and then to the __(C)__ or sperm duct. The vasa deferentia merge to form the urethra, which travels to the outside of the body through the penis.The cells located vasa deferentia merge to form the urethra, which travels to the outside of the body through the penis. The cells located between the seminiferous tubules are called __(D)__ cells and they are responsible for the formation of the male hormone, __(E)__. Show Answer

Q81) Fill up the blanks.
A functional mammary gland is characteristic of all female __(A)__. The mammary glands are paired structures (breasts) that contain glandular tissue and variable amount of fat.

The cells of __(C)__ secrete milk, which is stored in the cavities (lumens) of alveoli. The alveoli open into mammary tubules. The tubules of each lobe join to form a __(D)__ duct. Several __(E)__ ducts join to form a wider mammary ampulla which is connected to __(F)__ duct through which milk is sucked out. Show Answer

Q82) Fill up the blanks -
The female external genitalia include mons pubis, labia majora, labia minora, hymen and clitoris. __(A)__ is a cushion of fatty tissue covered by skin and pubic hair.

The opening of the vagina is often covered partially by a membrane called __(D)__. The __(E)__ is a tiny finger-like structure which lies at the upper junction of the two labia minora above the urethral opening. The __(D)__ is often torn during the first coitus (intercourse). However,it can also be broken by a sudden fall or jolt, insertion of a vaginal tampon, active participation in some sports like horseback riding, cycling etc. In some women the __(D)__ persists even after coitus.
