These club cells secrete glycosaminoglycans which protect the bronchiolar epithelium.
胞能分泌糖胺聚糖,来保护支气管内膜。
The extracellular component includes both the intravascular space - the space within the blood and lymphatic vessels and the interstitial space - the space between cells where you typically find fibrous proteins and long chains of carbohydrates which are called glycosaminoglycans.
胞外的部分包括管道内空间,即血管和淋巴管内的空间以及间质空间,即胞之间的空间,通常能找到纤维蛋白和叫糖胺聚糖(即黏糖)的长链碳水化合物。
