Endoscopic image of the human foetus in vivo,after 9 weeks,showing: the stomach (bottom,left),the coiled intestines (centre,right),and the umbilicus (top),which carries 2 arteries that remove deoxygenated blood and a vein that provides oxygenated blood for the foetus. The endoscope,a series of lenses and a fibre- optic light guide,is inserted through the cervix and manipulated until a "window" into the amniotic sac is found (ie an area where the wall is thinner) | |
