What is the speed of sound in liver tissue?

Explanation:
Liver tissue falls into the range of soft tissues where sound travels relatively fast because of its elastic properties. The speed of sound in such tissues is typically around 1,500 to 1,600 m/s, with liver commonly cited near 1,560 m/s. This value reflects the combination of density and stiffness in liver tissue and is also the number ultrasound systems often use as a practical assumption for depth calculations in the abdomen. The other options either represent speeds more typical of other tissues (for example, fat around 1,450 m/s) or are not characteristic of soft tissue (much lower values like 500 m/s), so the 1,560 m/s figure best matches liver tissue.
