Nomenclature
According to Terminologia Anatomica, the term "vasa recta renis" is an alternate name for "arteriolae rectae renis", and a separate term, venulae rectae renis, is used to identify the venous portion.
However, other sources consider "vasa recta renis" to refer to both the arterial and venous portions.
The "renis" is often omitted, but there do exist two other structures with the same name:
- vasa recta (intestines) (in the ileum and jejunum)
- the straight portion of the seminiferous tubule, though this is usually called the tubuli recti.
