because it divides the chest from the abdomen
This is the small and large intestine
Two descriptive methods of subdividing the abdomen are the nine-region system and the four-quadrant system. The nine-region system divides the abdomen into regions such as the right hypochondrium, epigastric, and left hypochondrium, among others, providing a detailed anatomical framework. In contrast, the four-quadrant system simply splits the abdomen into the right upper, right lower, left upper, and left lower quadrants, offering a more straightforward approach for clinical assessments and diagnoses.
In humans and other mammals the thorax and abdomen are separated by a sheet of muscle called the diaphragm. In insects like wasps and bees where there is a narrow region between the thorax and the abdomen this is called the petiole.
First the nucleus divides. Then the cytoplasm divides.

Anatomy breaks the human abdomen down into segments known as regions or quadrants. The most common method divides the abdomen into four quadrants: the right upper quadrant, left upper quadrant, right lower quadrant, and left lower quadrant. Alternatively, the nine-region system includes areas such as the epigastric, umbilical, and hypogastric regions, as well as the right and left hypochondriac, lumbar, and iliac regions. These divisions help in the diagnosis and treatment of abdominal conditions.
