Absorption in tissue energy transfer refers to energy absorbed by which of the following?

Absorption in tissue energy transfer refers to energy absorbed by which of the following?

• A. One layer reducing energy to deeper tissues
• B. All layers absorb equally
• C. No absorption occurs
• D. Reflection dominates energy transfer

Answer: (A)

Absorption in tissue energy transfer is about the energy that is taken up by tissue as the wave or energy passes through. Most of the energy is absorbed by the superficial layer, which reduces how much energy can reach deeper tissues. So the energy reaching deeper tissues is attenuated because the outer layer absorbs part of it. The other ideas aren’t correct because tissues don’t absorb equally at all depths, some energy is indeed absorbed (not zero), and while reflection can occur at boundaries, absorption specifically describes the energy captured by the superficial layer and its effect on diminishing energy deeper down.
