常见错误

❌ 错误:The cloaca is only for birds.

❌ 错误:I cleaned the cloaca in my backyard.

近义词辨析

sewer

sewer 通常指人造的污水管道系统,用于城市排水;而 cloaca 作为'阴沟'时,更强调其作为废物汇集处的比喻意义,或指自然形成的污水道,语域更正式或学术。

The city's sewer system is efficient. (指实际管道) / The river became a cloaca for industrial waste. (比喻性描述)

vent

vent 泛指出口或通风口,可以用于多种语境如气体或液体排出;而 cloaca 特指动物体内的泄殖腔,功能更具体,涉及排泄和生殖,不用于一般通风场景。

Air exits through the vent. (通用出口) / Waste exits through the cloaca. (特定解剖结构)
