Answer
The diagram shows the female reproductive system (fallopian tube, ovary, uterus, cervix, vagina); contraception prevents pregnancy, spaces births and controls population.
(a) The diagram shows the human female reproductive system. Parts: 1: Fallopian tube (oviduct); 2: Ovary; 3: Uterus; 4: Cervix; 5: Vagina.
(b) Contraception is the prevention of pregnancy by using methods such as condoms, oral pills, a copper-T or surgery. Three advantages of adopting contraceptive measures: (1) a proper gap can be kept between two pregnancies, which protects the health of the mother; (2) unwanted pregnancies are avoided; (3) the population is kept under control. Other correct advantages, such as protection from sexually transmitted diseases by barrier methods, are also valid.
