Upon entering the body, the virus encounters the epithelial cells lining the nasopharynx which is the part of your throat nearest your nose.

病毒进入体内后会遇到鼻咽部的上皮细胞；鼻咽指的是喉咙靠近鼻子的部位。

Air has to go from the nose through the nasopharynx into the laryngopharynx, through the larynx and then into the trachea.

空气从鼻腔进入鼻咽部，到达咽喉部，穿过咽喉进入气管。

Allergies might cause swelling of the tissue in the nasopharynx, or there might be swollen adenoid glands or tonsils because of an infection.

过敏反应可能会引起鼻咽部组织肿胀，或是存在感染引起的腺体或扁桃体肿大。

Although it's not always needed, diagnostic testing for RSV can be done by swabbing epithelial cells in the nasopharynx and looking for the presence of viral antigens.

可以通过擦拭鼻咽部上皮细胞，检查是否存在病毒抗原，但这一检查并不是人人都必要的。

Like, the authors of a November 2020 paper in Frontiers in Immunology hypothesize that some people do a better job of creating a defensive coating of mucus in their nasopharynx.

比如说，2020年11月发表在《免疫学前沿》杂志上的一篇论文的作者假设，有些人在鼻咽部位更容易形成一层具有防御性质的粘液涂层。

Below the nasopharynx and closer to the mouth is the second division of the pharynx, the oropharynx. The palatine tonsils, two rounded massed of lymphatic tissue, are located in the oropharynx.

在鼻咽下方并且更接近口腔的是咽的第二部——口咽，也称作腭扁桃体，为两团圆形的淋巴组织，位于口咽部。

The facial nerve also innervates the sublingual and submandibular glands, which secrete saliva, as well as the lacrimal gland which produces tears, and mucous membranes of the nose, mouth, and nasopharynx.

面神经同时也支配着舌下腺和下颌下腺，它们可以分泌唾液；以及产生眼泪的泪腺，还有口、鼻、鼻咽的粘膜。

But their presence in the nasopharynx is especially important, as that's where respiratory viruses like SARS-CoV-2 usually enter our bodies, and where scientists believe these viruses can hang out and multiply.

但他们在鼻咽中的存在则尤为显著，因为像新冠病毒这样的呼吸道病毒通常是通过鼻咽进入我们的身体，而科学家们则认为是因为病毒能在此逗留和繁殖。

M is for middle ear infection: DNS also predisposes to middle ear infection because Eustachian tube which is the only drainage source of middle ear, opens in nasopharynx and DNS can cause its obstruction and resulting in middle ear infections.

M 是中耳感染：DNS 患者更倾向于患中耳感染，咽鼓管是中耳唯一的引流源，在鼻咽部打开，DNS 可引起咽鼓管阻塞，导致中耳感染。
