The liver is unique among solid organs in its susceptibility to trauma that can lead to significant hemorrhage into the abdominal cavity. It is the largest solid organ in the body and is highly vascular, containing a rich blood supply from both the hepatic artery and the portal vein. When the liver sustains a traumatic injury, such as a laceration or rupture, it can result in the rapid release of large volumes of blood directly into the peritoneal cavity, which can lead to hypovolemic shock if not addressed promptly.

In contrast, other organs listed do not behave in the same way when it comes to trauma. The heart, although a vital organ, is not located within the abdominal cavity and typically releases blood into the chest cavity rather than the abdomen. The lungs are also not solid organs in the same sense; rather, they are spongy and involved in respiration. While lung injuries can lead to significant complications, they do not cause bleeding into the abdominal cavity. Skin, on the other hand, is considered an external organ and does not release blood into the abdominal cavity. Instead, it can bleed externally when traumatized.

Therefore, the liver is the only solid organ listed that can release blood into the abdominal cavity following trauma, making
