In the human reproductive process, two kinds of sex cells, or gametes (GAH-meetz), are involved. The male gamete, or sperm, and the female gamete, the egg or ovum, meet in the female's reproductive system. When sperm fertilizes (meets) an egg, this fertilized egg is called a zygote (ZYE-goat).

Answer:

Hi here is your answer.

Explanation:

In human beings sexual mode of reproduction takes place. It means human beings reproduce their offspring through sexual mode of reproduction, where the fusion of gamets(sperm and ovum) takes place by the process called 'fertilisation'. This is done when male reproductive system (penis) goes inside female reproductive system (vagina) during mating. It is only during this process when penis releases sperm to fuse with ovum which is present in oviduct. After the fusion of male and female gamets zygote is formed in the uterus. Before the formation of zygote the uterus is embedded with lot of blood cells and capillaries on the inner lining of embryo so that it can develop the fertilised ovum to develop into a complete baby.

The embryo grows and becomes surrounded by structures that provide support and nourishment.

The fetus grows inside the uterus until pregnancy ends with labor and birth. By then all body systems are in place—including the reproductive system that can one day help produce another human being. Fertilization normally takes place in the female's Fallopian tube, which connects the uterus (womb) with the ovary. The uterus is made of muscle and it stretched to allow the baby's growth throughout the months of pregnancy. Every month one of the ovaries, in turn, releases an egg (ovum) which passes slowly along the tube towards the womb cavity.

Development: By 25 days from fertilisation, the body is developing. Head and trunk appear and tiny arm buds begin to form, followed by leg buds. Because the central nervous system (brain, spine and spinal cord) is so important, governing sensory and motor functions, the embryo's body is designed for rapid growth of head and back.

In the last weeks of pregnancy, the baby lies head downwards, as the head is normally the first part emerging at birth.

Hope it helps.
