Final answer:
The abdomen is divided into nine regions in the peritoneal cavity called the abdominopelvic regional approach. It is also divided into four quadrants using the simpler quadrants approach commonly used in medicine.
The answer is option ⇒D.nine
Step-by-step explanation:
This is called the abdominopelvic regional approach. It uses one horizontal line below the ribs, one above the pelvis, and two vertical lines dropped from the midpoint of each clavicle to create nine regions.
In addition to the regional approach, there is also a simpler quadrants approach commonly used in medicine. It divides the abdomen into four quadrants by using one horizontal and one vertical line that intersect at the patient's umbilicus (navel).
The answer is option ⇒D.nine
