Following blunt trauma to the spleen, what causes disseminated intravascular coagulation (DIC) due to widespread platelet aggregation?

💡 Explanation

DIC following splenic trauma arises because the damaged spleen releases tissue factor into the circulation, which initiates the coagulation cascade, leading to excessive platelet aggregation and fibrin formation. Therefore, option C is correct; rather than antithrombin III increase which inhibits coagulation.

• If the radius of a blood vessel decreases by half due to vasoconstriction, which consequence follows regarding blood flow, assuming constant pressure gradient and blood viscosity?
• Why does excessive mechanical loading during intense weightlifting eventually lead to stress fractures in bone undergoing remodeling?
• During long-term potentiation within hippocampal neurons during sleep, which consequence follows increased synaptic glutamate release?
• Why does perceived brightness diminish at extreme angles of retinal illumination in peripheral vision?
• Why does significant muscle sarcopenia during aging impair glucose tolerance more than simple disuse atrophy?
• Why does administering antipyretics reduce fever, but not during exercise-induced hyperthermia?
