Assume that the body has been sectioned along three planes: (1) a median plane, (2) a frontal plane, and (3) a transverse plane
Anit [1.1K]

Answer:

lungs and kidneys

Explanation:

The median plane divides the body into two halves through a mid line.

The transverse plain is also known as the axial plane and it divided the body into the upper part and a lower part.

The frontal plane is also known as the coronal plane. It divided the body into the dorsal and ventral sections. The dorsal and ventral sections are the front and back sections ( belly and back).

Lungs and kidneys are the only parts which cannot be seen through all the three plains.
