Human foetus. Illustration of human foetal development, week 13-14 after fertilisation. The head has a visible nose, mouth and chin. The head is proportionately large although the body is elongating at this stage. Fingers and toes are formed. Most of the organs have developed, but require growth. The genitals have formed and the sex is determined. The abdomen grows rapidly during this time, with the liver greatly enlarged to produce red blood cells until the bone marrow (as yet undeveloped) takes over this function.
