One is that cells form tissues that are mechanically intact, they have mechanical integrity because they can adhere to one another.
一是具有机械完整性的组织是由细胞构成,组织之所以具有机械完整性,是因为细胞能够互相黏附在一起
One, at the first level, what are the cells that make up that tissue?
其一,在第一个层次上,构成那个组织的是哪些细胞呢
organ systems like the cardiovascular system are made up of tissues.
器官系统如心血管系统等,由组织构成
How do those differences between cells contribute to the properties of the tissues, which contribute to the properties of the organs, which contribute to the properties of a person and this maintenance of homeostasis?
这些差异化的细胞,是如何构成具有不同属性的组织,这些组织又构成具有不同属性的器官,器官又构成了不同的人,它们是如何维护内稳态呢
So organs are made up of combinations of tissues where all the tissues are collections of cells that are doing some function, nervous tissue, muscular tissue, epithelial tissue, those are examples of tissues that form organs.
所以器官是由各种组织组合而成,所有的组织都是,具有某些功能的细胞集合,神经组织,肌肉组织,上皮组织,这些都是由组织构成器官的例子
This is a picture that I showed you before, but basically tells you something that you already know, that humans are made up of organ systems, organs and organ systems, those organs are composed of tissues.
这张图我给你们看过,简单的说明了一些常识,即人体由器官系统构成,器官和器官系统,其中器官由组织组成
