The figure represents the female system of a mammal. Study the diagram and answer the questions that follow: (i) Label the parts 1 - 5 . (ii) Where does fertilization take place? (iii) Name the structure where ovum is implanted.

(i) The labelling of the diagram is as follows: 1 . The part labelled as 1 is the fallopian tube 2 . The part labelled as 2 is the ovary 3 . The part labelled as 3 is the uterus 4 . The part labelled as 4 is the vagina 5 . The part labelled as 5 is endometrium (ii) During copulation (coitus) semen is released by the penis into the vagina (insemination). The motile sperms swim rapidly, pass through the cervix, enter into the uterus and finally reach the ampullary region of the fallopian tube. The ovum released by the ovary is also transported to the ampullary region of the fallopian tube where fertilisation takes place. (iii) Once the embryo reaches the blastocyst stage, approximately five to six days after fertilization, it hatches out of its zona pellucida and begins the process of implantation and is implanted in the walls of uterus.

The diagram shown is the lateral section of a testis of man. Study it carefully and answer the questions that follow: (i) Label the parts 1 - 4 of the diagram. (ii) State the functions of the parts labelled 1 and 3 . (iii) Draw a labelled diagram of a sperm.

(i) The labelling of the parts are as follows: The part labelled as 1 is vas deferens The part labelled as 2 is vasa efferentia The part labelled as 3 is the epididymis The part labelled as 4 is seminiferous tubules (ii) The functions are as follows: 1 - The vas deferens transports mature sperm to the urethra in preparation for ejaculation. 2 - The vasa efferentia are the ductules leading from the rete testis to the epididymis, which leads to vas deferens. 3 - The primary functions of the epididymis are sperm transport and sperm maturation. (iii) Structure of human sperm.
