Around the Haversian canals, there are concentric lamellae, which look a bit like tree rings.

在哈弗斯管周围有心薄片，看起来有点像树的年轮。

In the center of these osteons, there are hollow spaces called Haversian canals, which contain the blood supply and innervation for the bone cells.

在这些骨单位的中心，这个中空的部分被称作哈弗斯管，供了为骨细胞供应血液以及神经支配的空间。

In osteoporosis, there's thinning of the cortical bone, widening of the Haversian canals and a decrease in the number of trabeculae in the spongy bone.

骨疏症中，皮骨会变薄、哈弗斯管变、骨内的骨小梁数目减少。

So with osteoporosis, abnormal findings include fewer trabeculae in the spongy bone and thinning of the cortical bone, as well as the widening of the Haversian canals.

那么，骨疏的异常包括骨中的骨小梁会减少，皮骨变薄，还有哈弗斯管变。

It's also dotted with features known as Haversian canals, which are the pathways the blood vessels followed to bring nutrients to the fast-growing tissue.

它也散布着被称为哈弗斯运河的特征，这是血管为快速生长的组织带来营养所遵循的途径。
