Viscera are the internal organs of the body — heart, lungs, liver, stomach, intestines — taken together, especially those in the chest and belly. It is a plural noun and behaves like one: the viscera are, not is. The singular, viscus, exists but is rare outside medical writing.

Viscera areViscera指的是 the internal organs of the body身體內臟器官 heart, lungs, liver, stomach, intestines（心、肺、肝、胃、腸等） taken together的統稱 especially those in the chest and belly尤其是胸腔和腹腔裡的器官 It is a plural noun這是個複數名詞 and behaves like one用法也跟複數一樣 the viscera are, not is要說the viscera are，不是is The singular, viscus, exists單數形viscus是存在的 but is rare outside medical writing但除了醫學文章以外很少見

The word is technical and clinical. Doctors, biologists, and anatomy textbooks use it; ordinary people say "organs", "insides", or in a butcher's context "guts" or "offal". So when viscera turns up in non-medical writing, it is usually there for effect — the cold precision of the word makes a scene of injury or dissection feel more exact and more disturbing.

The word is technical and clinical這個字很專業、很臨床 Doctors, biologists, and anatomy textbooks use it醫生、生物學家和解剖學教科書會用這個字 ordinary people say "organs", "insides"一般人則說「organs」、「insides」 or in a butcher's context "guts" or "offal"或是在肉販的情境下說「guts」或「offal」 So when viscera turns up in non-medical writing所以當viscera出現在非醫學的文章裡 it is usually there for effect通常是為了製造效果 the cold precision of the word這個字冷冰冰的精確感 makes a scene of injury or dissection feel more exact and more disturbing會讓受傷或解剖的場景顯得更精確、更令人不安

The related adjective visceral has drifted a long way from the body and is the form learners meet far more often. A visceral reaction is one you feel in your gut before you think it through — instinctive, physical, not reasoned. "I had a visceral dislike of the place." That sense is now the everyday one; a doctor might still use visceral in the literal anatomical sense, but almost nobody else does.
