Fight for Life, a six-part series, uses computer-generated imagery (CGI) and specially shot material to reveal the fight for survival from inside the human body.
Each episode focuses on a different life stage showing the dramatic story of how the human body changes from birth, through to adulthood and old age, and the way in which it reacts when its defences are threatened.
Part 1: Birth
The day a baby is born is the riskiest of its life. How does the body of a newborn react when there are complications in the delivery room? What happens to a mother's body in order to carry it through its journey of delivering a baby?
At only two hours old, baby Gabriel is already facing death. He has meconium aspiration syndrome, a result of inhaling his own excretion in the womb. Fight for Life follows his crucial first few weeks after he's rushed to Great Ormond Street Hospital for life-saving treatment.
The programme also follows a woman who needs a caesarean because her baby's in a breech position (feet first). The operation takes a turn for the worse when the medical team discovers the baby's umbilical cord is wrapped around his neck.
Birth, even without complications, is a difficult and potentially traumatic event. Watch as baby Lily moves from inside the womb, and see what happens when her body begins to take charge of its own survival.
