What is the vein that carries blood from heart to tail?

Answer 1

Trick question! It is a series of arteries that carries the blood from the heart to the tail. The veins return the blood from the tail back to the heart.

The blood travels the majority of the distance down the body's primary artery, the aorta. From there, there is a significant amount of branching. For example, one path involves - aorta to internal iliac artery to caudal gluteal artery to the lateral caudal artery - Another path involves - aorta to median sacral artery -

BUT the tail is also supplied by Dorsal lateral caudal artery, Ventral lateral caudal artery, and Median caudal artery. The entire meshwork of vessles do not exist as individuals all to themselves but overlap through a process known as collateral circulation.
