Hi Answer:
Q. Give 2 examples of how a specific tissue affects the speed of sound as it travels through the body. ?
Answer: First of all, we must know that the sound travels fast, if there is no hurdle in its path. As more the obstacles and hurdle in the way, its speed goes down. As in our body, there are different tissues are present which are made of different kind of cells. Some of them are solid (bones), some are liquid (Blood connective tissue) and some are semisolid. The bones are made of calcium/ phosphorous particles and solid in-state means the atoms in bones are present very close to each other and have very fewer movements. Hence when sound passes from them it gets minimum hindrance and it travels very fast whereas in case of liquid (such as blood) the atoms are randomly dispersed and have a large extent of movement and this atomic movement creates hindrance in the speed of sound and reduces its speed. In case of gases, the speed reduced more because they case maximum hindrance to the sound. The speed of sound has a maximum in bone followed by muscles, blood, soft tissues and lungs.
