This paper explores the possibility of the existence of wormhole geometries coupled with relativistic matter configurations by taking a particular model of gravity (where T is the trace of energy-momentum tensor). For this purpose, we take the static form of spherically symmetric spacetime and after assuming a specific form of matter and combinations of shape function, the validity of energy conditions is checked. We have discussed our results through graphical representation and studied the equilibrium background of wormhole models by taking an anisotropic fluid. The extra curvature quantities coming from gravity could be interpreted as a gravitational entity supporting these non-standard astrophysical wormhole models. We have shown that in the context of anisotropic fluid and gravity, wormhole models could possibly exist in few zones in the space of parameters without the need for exotic matter.
