This article examines gravity from the perspective of living systems rather than equations alone. Cosmic Influx Theory (CIT) is treated here as equivalent to gravity in measured effects and calculated results, but different in proposed mechanism: instead of attraction or spacetime curvature, CIT interprets the phenomenon as a continuous Influx acting on matter. The article argues that organisms do not directly register abstract gravitational theory; they register load, shear, pressure, support, balance demand, and whole-body adaptation. Special attention is given to the vestibular system, especially the otolith organs, as a biological example of sensor-level mechanical registration. The accelerometer is used as a technical parallel, since both biological and instrumental systems respond to support and relative displacement rather than to theory as such. Across posture, circulation, microgravity adaptation, and life across species, the paper proposes that CIT may offer a more direct cause-language for what living systems are responding to. The claim is limited but important: this article does not prove CIT in full, but presents biological and operational indications that the experienced phenomenon called gravity may be interpreted, at sensor level, as Influx.
