Interestingly, once the blood leaves these glomeruli it does not enter into venules.

有趣的是，当动脉离开这些肾小球后，并不进入小静脉。

The oxygen-rich blood moves into a venule and then, eventually, into a pulmonary vein that dumps the blood into the left atrium.

富含氧气的汇入小静脉，最终进入肺静脉；肺静脉将入左心。

And blood pressure in veins is extremely low compared with pressure in arteries. The smallest veins, called venule , are formed by the union of capillaries.

静脉 壁略厚于毛细管壁。随着静脉变大，管壁变厚。

On the other end of the capillary bed there's a venule, and the arteriole and venule are usually directly connected by a vessel called the metarteriole.

在毛细管床的另一端，有小静脉；小动脉和小静脉通常是由一种叫后动脉的管直接连接的。

The fetal layer of the placenta on the other hand is called the chorion, which is a tissue that has fingerlike projections called chorionic villi which contain tiny fetal arterioles and venules.

胎盘的“胎儿层”也被称为绒毛膜；这是一种有绒毛膜绒毛这种手指状突起的组织，富含小的胎儿动脉和静脉。

Loaded up with carbon dioxide, the blood turns that dark red color again (shown as blue) and starts the return journey to the heart by going into small venules and then larger veins.

随着二氧化碳的增加，会再次变成暗红色（画为蓝色）并开始返回心脏，先是进入小静脉，然后是较大的静脉。

The cells send their CO2 and other junk out to the venal end of the capillary exchange where the capillaries unite into venules, and then merge into veins that head back to the heart.

细胞将二氧化碳和其他垃圾输送到毛细管交换的静脉端，毛细管在那里结合成小静脉，然后合并成静脉返回心脏。
