Blastocyst

Real World Example

Imagine trying to organize a group of people into a tightly packed elevator while ensuring everyone has enough space to be comfortable. This is similar to how a blastocyst forms in early mammalian development, where cells organize themselves into a hollow structure to create an optimal environment for growth. Just as people in an elevator position themselves around the walls to maximize space and comfort, the cells in a blastocyst arrange themselves around the perimeter, creating a hollow ball that allows for further development and specialization.
