Which term describes organs that bleed heavily when injured?

• A. Solid organs
• B. Hollow organs
• C. Glandular structures
• D. Lymphatic organs

Answer: (A)

Bleeding tendency after injury is driven by how vascular an organ is. Solid organs have dense, highly vascular tissue and a capsule, so when they’re damaged they tend to bleed a lot and can cause rapid, life-threatening hemorrhage. Liver, spleen, kidneys, and similar organs are classic examples. Hollow organs have thinner walls and their injury often leads to leakage of contents rather than brisk external bleeding. Glandular structures and lymphatic organs aren’t defined by heavy bleeding in trauma; the key idea is that the rich vascularity of solid organs makes them prone to significant hemorrhage when damaged.
