The suffix '-porosis' refers to which of the following?

The suffix '-porosis' derives from the Greek word "poros," meaning passage or pore. When used in medical terminology, it specifically indicates a condition characterized by a reduction in the density or quality of bone, leading to increased porosity. This condition reflects that the bones have become more porous and fragile, susceptible to fractures and other issues.

In the context of medical terminology, "-porosis" is often seen in disorders such as osteoporosis, where there is a significant decrease in bone mass due to this increased porosity. This knowledge is important in the field of medicine, particularly in understanding conditions related to bone health, aging, and metabolic processes.

The other options do not align with the definition of the suffix; for instance, "drooping" (which refers to a sagging condition), "spitting" (which involves expelling something from the mouth), and "excessive flow" (which could relate to conditions that involve increased bodily fluids) are unrelated to the concept of porosity or changes in bone density.
