Explain some Physiological Changes during Pregnancy?

A whole new life begins at conception. Organ systems develop rapidly and nutrition plays many supportive roles. Pregnancy from conception to birth usually lasts 40 weeks (10 lunar months/menstrual cycles) in humans. During this period, the unborn child grows from a single cell to an infant that is ready for life outside the womb. Many physical changes also take place in the mother to support her developing offspring, regulate her own (maternal) metabolism and prepare her for labour, birth and lactation.

Changes in the mother are anatomical, physiological and complex, affecting almost every function of the body. They are an integral part of the maternal - foetal system, which creates the most favourable environment possible for the developing child. Many of these changes are apparent in the very early weeks.
