Final answer:
A structure closer to the belly is described as ventral, indicating its position towards the front of the body.
Step-by-step explanation:
A structure that is positioned more closely to the belly can be described as ventral. This term specifically denotes the front or direction toward the front of the body, as opposed to dorsal, which refers to the back or direction toward the back of the body. The ventral cavity is an example of a body cavity located toward the front, housing organs such as the heart, lungs, and abdomen, among others. Similarly, talking about planes, the midsagittal plane divides the body into equal right and left portions, while the transverse plane divides it into superior (upper) and inferior (lower) portions.
