Consider the following four statements (A-D) and select the option that correctly identifies the true (T) and false (F) ones.
(a) The opening of the vagina is often covered partially by a membrane called hymen.
(b) The edges of the fallopian tube posses finger like projections called Isthmus.
(c) The Alveoli cells secrete milk which is stored in their cavity.
(d) The clitoris lies at the upper junction of two labia majora below the urethral opening.

Each fallopian tube is about 10-12 cm long and extends from the periphery of each ovary to the uterus the part closer to the ovary is the funnel-shaped infundibulum. The edges of the infundibulum possess finger-like projections called fimbriae, which help in collection of the ovum after ovulation. The opening of the vagina is often covered partially by a membrane called hymen. The clitoris is a tiny finger-like structure which lies at the upper junction of the two labia minora above the urethral opening. A functional mammary gland is characteristic of all female mammals. The mammary glands are paired structures (breasts) that contain glandular tissue and variable amount of fat. The glandular tissue of each breast is divided into 15-20 mammary lobes containing clusters of cells called alveoli. The cells of alveoli secrete milk, which is stored in the cavities (lumens) of alveoli.
