Human Development

This overview explores the critical stages of human development, beginning with fertilization, where a zygote forms within 12 hours of sperm meeting egg. It highlights the pre-embryonic period, lasting until implantation, and progresses through the embryonic period, which includes organ development and the formation of essential systems like the nervous and reproductive systems. Additionally, it discusses the fetal period, where significant growth occurs, leading to birth. Comprehending these stages is vital for understanding human biology and reproductive health.
