Which term means tissue death?

Which term means tissue death?

• A. -necrosis
• B. -itis
• C. -malacia
• D. -osis

Answer: (A)

Tissue death is called necrosis. The root necro- means death, and necrosis is the term that names the process of cells or tissue dying. It describes what happens when cells lose their blood supply, are damaged by toxins, infected, or harmed by trauma. This is different from inflammation (inflammation is -itis), softening of tissue ( -malacia), or a general abnormal condition or process ( -osis). For example, heart muscle tissue can undergo necrosis after a heart attack, and dead tissue in a limb can become gangrenous through necrosis.
