腔和四个窦相连，窦是位于腔周围含气的骨质腔，又称旁窦。

Your vocal tract is basically the entire mechanism that shapes sounds from your vocal cord to your nasal cavity.

声道基本上是从声带到腔塑造声音的整个机制。

Reindeer have 25% more blood vessels packed in their nasal cavities than we do, so they get rid of excess heat through their noses.

Dogs and other animals that rely mainly on smell tend to have elongated nasal cavities, which drain down and back with gravity, the correct way.

主要依靠嗅觉的狗和其他动物往往有细长的腔，腔在重力作用下向下和向后排出，这是正确的方式。

In other words, sometimes a person might have no allergic reaction on the skin test, but have a localized allergic reaction affecting the nasal cavity and eyes - that's low sensitivity.

换言之，一个在子和眼睛局部存在着敏性反应的患者在做皮肤点刺试验时可能出现假阴性的结果，这就是所谓的低敏感性。

These neurons migrate down from the olfactory placode and get embedded in the cribriform plate, which is a bone plate that separates the nasal cavity from the brain, forming the olfactory bulb.

这些神经元从嗅觉基板迁移下来，并嵌入筛板中，即将腔与大脑隔开的骨板，从而形成嗅球。

During swallowing, the soft palate and uvula move upward to prevent food from entering the nasal cavity, the uvula also helps to guide the food into the pharynx.

在吞咽期间，软腭和悬雍垂向上移动以防食物进入腔，悬雍垂也有助于将食物引入咽部。

Nose hairs at the entrance of the nasal cavity get coated with that mucus and are able to trap large particles of dust and pollen as well as bacteria, forming tiny clumps of boogers.
