Overview
- 1概述：免疫系统是人体的天然防御屏障。它并不是一个单一的器官，而是由多个部分（如淋巴结、脾脏、白细胞等）组成的复杂网络，协同工作以维持生命安全。2) 用法模式：在中文里，‘免疫系统’通常作为主语或宾语。常见的动词搭配包括‘增强’（strengthen）、‘提高’（improve）、‘削弱’（weaken）或‘攻击’（attack）。3) 常见语境：该词常出现在健康讲座、医学报道、体育锻炼建议以及关于营养和疾病预防的日常对话中。例如，在讨论流感季节时，人们常会提到如何保护免疫系统。4) 近义词辨析：‘免疫系统’侧重于生理结构和整体机制，而‘免疫力’（Immunity）则侧重于身体抵抗疾病的具体能力。虽然两者常互换使用，但在严谨的科学语境下，‘系统’指代结构，‘力’指代强度。
