About this document
Pathophysiology of Normal Delivery by Jose Bryan Nacilla is a document available to read on EtoBox.
Fertilization occurs when a sperm and ovum unite. The zygote undergoes cell division and becomes a morula by day 3, and a blastocyst by day 4. On day 6, the blastocyst implants into the uterine lining and embryonic development begins. Embryonic development occurs over 8 weeks in 3 stages: increasing cell number and elaboration, morphogenesis through cell movement, and differentiation of physiological processes. Fetal development then occurs from week 9 until birth via vaginal delivery.
