What is the most commonly injured organ from blunt trauma?

  1. Spleen

  2. Liver

  3. Kidney

  4. Stomach

The correct answer is: Liver

The liver is the most commonly injured organ from blunt trauma due to its size, location, and vascular nature. Being one of the largest organs in the abdominal cavity, the liver is susceptible to injury from direct blows to the abdomen, car accidents, falls, or any significant impact that can occur in blunt trauma scenarios. Additionally, the liver is highly vascularized, meaning it contains a large number of blood vessels. When the liver sustains an injury, particularly from blunt force, it can lead to significant internal bleeding given its rich blood supply. Understanding the anatomy and physiology of abdominal organs helps in recognizing why the liver is vulnerable compared to others, such as the spleen, kidneys, or stomach, which, while they can also be injured, do not have the same level of commonality as the liver in blunt trauma cases.
