| The postcava enters the liver in a special prolongation of the liver substance. |
| The distal portions of the postcardinal veins form the efferent renal branches and the ascending trunks of the postcava. |
| The postcava is well developed, formed by large efferent renal veins. |
| The anterior vena cava, also known as the precava, drains the head end of the body, while the posterior vena cava, or postcava, drains the tail, or rear, end. |
