1. 定义：bronchi是指人体呼吸系统中连接气管和肺部的两个主要支气管。它们将空气传递到肺部，并且也是呼吸系统的主要通道之一。
2. 解剖学：bronchi可以分为左右两个，每个支气管在分支成越来越小的细支气管之前都会分成多个支枝。这些支枝进一步分支成为无数的肺泡，便于氧气和二氧化碳的交换。
3. 疾病和医学：支气管炎是一种常见的呼吸系统疾病，它通常是由病毒或细菌感染引起的。支气管扩张症是一种慢性肺部疾病，它导致肺部气道的扩张和气流阻塞。
4. 生理学：当空气进入肺部时，支气管会通过肌肉的收缩和松弛来控制气流的流向和速度。这种调控对于保持肺部的健康和正常呼吸至关重要。
5个中英例句：
1. The bronchi are the two main branches of the trachea that lead into the lungs.（支气管是气管的两个主支，通向肺部。）
2. The bronchial tubes in the lungs are lined with small hair-like structures called cilia.（肺部的支气管内壁有着数以万计的纤毛，它们能清理肺部的杂质。）
3. Asthma is a chronic respiratory disease that causes inflammation and narrowing of the bronchi.（哮喘是一种慢性呼吸系统疾病，会导致支气管炎症和收缩。）
4. The bronchial tree is a highly branched network of airways that extends throughout the lungs.（支气管树是一种高度分枝的空气通道，遍布肺部。）
5. Chronic bronchitis is a condition characterized by inflammation and thickening of the bronchi, leading to cough and difficulty breathing.（慢性支气管炎是一种疾病，特征是支气管的炎症和增厚，导致咳嗽和呼吸困难。）
