The Pregnancy & Birth chart presents a detailed overview of the process from conception to birth. The overall structure of the female reproductive system is illustrated with smaller images showing the zygote stages. Each trimester is shown graphically with an overall view and a close-up view of the developing fetus. Heavy gauge 3ml lamination with sealed edges and two metal eyelets for hanging makes chart highly durable. Write-on/wipe-off with dry erase marker (not included).
