How do solid internal structures typically respond to trauma?

• A. Crack
• B. Tear
• C. Burst
• D. Expand

Answer: (D)

Solid internal structures respond to trauma chiefly by expanding due to edema and hemorrhage. When these organs are injured, fluid and blood accumulate in the tissue, causing swelling and an increase in size. This swelling raises internal pressure and can impair perfusion if the situation worsens. Terms like crack, tear, or burst describe direct mechanical rupture or fissuring, which are not the typical early response for solid organs; expansion from edema and hematoma formation is the common pattern you see as the body reacts to injury. Examples include liver and spleen contusions where the organ enlarges from swelling and bleeding rather than suddenly splitting apart.
