Introduction

The journey of life starts from conception, where a sperm and an egg meet and fuse to form a single cell called a zygote. This zygote will go through a series of development stages, eventually leading to the birth of a human baby. In this article, we will discuss how a human baby develops in the womb.

Week 1 – Fertilization

Fertilization occurs when a sperm penetrates the egg. Once fertilized, the egg divides into many cells and travels down the fallopian tube towards the uterus. This journey can take up to a week.

Week 2 – Implantation

Once the fertilized egg reaches the uterus, it will implant itself into the uterine lining. This is where the placenta, which will provide oxygen and nutrients to the growing embryo, starts to form.

Week 3 – Formation of the Embryo

During this week, the embryo begins to form. The neural tube, which will eventually become the brain and spinal cord, also starts to form. The heart also starts to develop and will begin beating by the end of the week.
