What Is Asthma And What Are Some Of The Common Symptoms?

Asthma is a chronic lung disease
喘息は慢性肺疾患です
that has two main components.
それは２つの主要なコンポーネンツがあります
One of them is inflammation,
ひとつは炎症です
which is irritation and the swelling of the airways.
それは気道の過敏と腫れです
The other is bronchoconstriction,
他方は気管の閉塞です
which is when the smooth muscles of the airway tighten up.
それは気道の平滑筋が締まるときに起こります
And so both of these together cause a narrowing of the airway
そしてこれらが一緒に働いて気道の狭窄を引き起こし
and make it harder to breathe.
呼吸を困難にします
Common symptoms of asthma are shortness of breath;
喘息の一般的徴候は　息切れです
wheezing, a musical sound that comes from having a narrowed airway;
喘鳴　気道狭窄による音楽的な音です
cough; and then a sense of chest tightness.
咳と　そして胸部の締め付け感です
