The number of vertebrae facing the kidney in lower vertebrates is greater than in man. So, the answer is a. greater than one.
Solución
-
In lower vertebrates (such as fish and amphibians), the functional kidney is the mesonephros. This kidney is arranged segmentally along the vertebral column and therefore “faces” (i.e., is associated with) a relatively large number of vertebrae.
-
In man, the definitive kidney is the metanephros. It forms as a compact organ in the lumbar region (roughly between
and ) and is related to only a few vertebrae, rather than extending along many segments. -
Thus, when comparing the number of vertebrae facing the kidney in lower vertebrates to that in man, we have
- Therefore, the correct answer is: greater than one.

In lower vertebrates, such as reptiles and amphibians, the number of vertebrae associated with the kidney can vary significantly, usually numbering more than in humans. For instance, many lower vertebrates have a larger number of vertebrae due to a longer body structure. In contrast, humans have a more regulated structure with fewer vertebrae directly associated with the kidney region. Thus, the ratio of the number of vertebrae facing the kidney in lower vertebrates compared to humans is likely greater than one. The answer is (a) greater than one.
Moreover, it’s fascinating to note that the evolution of vertebrates has led to diverse adaptations to their environments, influencing not just the number of vertebrae but also their functions. For example, in mammals, a more complex kidney structure has developed, which may mitigate the need for a higher vertebral count in close association with renal organs. This evolutionary journey emphasizes the intricate balance between anatomical structure and function across species!
