Movement of material from the intestines into the vascular system is termed what?

• A. bacterial translocation
• B. subcutaneous emphysema
• C. agonal edema
• D. gangrene

Answer: (A)

The movement of material from the gut into the vascular system happens when the intestinal barrier is breached, allowing bacteria or endotoxins to pass into sterile tissues and the bloodstream. This process is called bacterial translocation. It occurs when the mucosal barrier is compromised due to injury, stress, or disease, increasing permeability and enabling microbes that normally stay in the gut to reach mesenteric lymph nodes and sometimes the systemic circulation. This can contribute to sepsis and systemic inflammation, especially in conditions like severe liver disease, critical illness, or extensive gut injury.

Other options refer to different processes: subcutaneous emphysema is air beneath the skin from trauma or pneumothorax, agonal edema is edema associated with the dying process, and gangrene is tissue death from loss of blood supply or infection. None describe the transfer of gut material into the vascular system.
