What is the Latin phrase meaning "form follows function" relevant to biological systems affected by radiation?

The phrase "forma et functio," which translates to "form follows function," is particularly relevant in the context of biological systems and their response to radiation. This principle emphasizes that the structure (form) of biological entities—like cells, tissues, and organs—is intrinsically linked to their roles and activities (function). In the study of radiation biology, understanding how different forms of biological structures respond to ionizing radiation is crucial, as changes in these structures can lead to alterations in their function.

When radiation interacts with biological tissues, it can cause damage at the molecular and cellular levels, which may be reflected in the altered form and subsequently in the function of those biological entities. For example, if radiation damages the DNA within a cell, the resultant structural changes may impair the cell's ability to replicate or perform its designated biochemical functions. Thus, the interrelationship between form and function is vital for understanding the effects of radiation on living organisms.

Other phrases listed do not encompass the concept of form and function in biological contexts. "Carpe diem" refers to seizing the day and does not relate to biological design principles. "Cogito, ergo sum" translates to "I think, therefore I am," focusing on consciousness rather than biological structure-function relationships.
