Correct Response: B. Biomechanics works specifically with forces and structural mechanisms within the body. This includes the creation of joint implants, better corrective surgeries, and prosthetic, orthopedic, and therapeutic devices. Bioengineering is a much broader category that includes all engineering related to the science of living things. Some examples include genetic engineering, diagnostic devices, and even food production technology. Biomechanics is one of many fields included within the field of bioengineering. Hence, bioengineering is not a field within the field of biomechanics (A). The relationship is the exact opposite. Bioengineering is not limited to large-scale structures (C), and biomechanics is not related to individual cells. While biomechanics is related to large-scale structures (D), bioengineering is related to far more than just individual cells.
