Which organs are considered solid and may bleed when injured?

• A. Spleen, liver, kidneys, and pancreas
• B. Lungs, heart, brain
• C. Stomach, intestines, colon
• D. Muscles, bones, tendons

Answer: (A)

Solid organs have dense tissue with rich blood supply, so they are prone to heavy bleeding when injured. In the abdomen, the classic solid organs are the spleen, liver, kidneys, and pancreas. Blunt or penetrating trauma to these organs can cause rapid internal hemorrhage and shock because their parenchyma is highly vascular and they’re encapsulated, making bleeding hard to control. Hollow organs like the stomach, intestines, and colon tend to leak contents when injured rather than bleed profusely; injuries to the chest or brain involve different organs and injury patterns. Muscles, bones, and tendons aren’t the abdominal solid organs and have different bleeding dynamics.
