To build bone, osteoblasts secrete osteoid, which is an organic matrix made of type 1 collagen.

在构建骨的过程中，成骨细胞分泌类骨质，它是一种由1型胶原组成的有机质。

This means that osteoblasts don't have enough calcium and phosphate to deposit into the organic matrix.

这意味着成骨细胞没有足够的钙和磷可以沉积到骨有机质中。

First, an organ called the mantle secretes an organic matrix of proteins and other molecules to construct a scaffold.

首先，一种叫做地幔的器官分泌一种由蛋白质和其他分子组成的有机基质来构建支架。
