The answer to the given question will be that the muscles that guard the entrances and exits of the internal passage are known as sphincter (circular muscles).

  • Due to their structure and controllability, skeletal circular muscles differ from their smooth muscle counterparts.
  • The muscularis mucosa, which is mostly found in the stomach, is composed of smooth muscle.
  • The longitudinal layer shortens the tract while the circular muscle layer in the muscularis externa prevents food from moving backward.The human body contains at least 50 or 60 different types of sphincters.
  • Some are quite small, like the many precapillary sphincters that line the circulatory system's blood vessels.
  • Lower esophageal sphincter (LES), pyloric sphincter (PS), ileocecal sphincter (ICS), and internal sphincter are the four different smooth muscle sphincters found in the GI system (IAS).

Hence, the answer is that the muscles that guard the entrances and exits of the internal passage are known as sphincter (circular muscles).

How could the movement of tectonic plates create another supercontinent like Pangaea
Margaret [11]
<span>When the landmasses are again collected together in a specific area

The Pangea theory supports the theory of plate tectonics because it is based on the idea that all the present continents were one super-continent. For reasons still unknown, the super-continent got separated and created separate smaller continents. This theory also supports the fact that this movement will continue until the day arrives when all the smaller continents will again merge in a different configuration to create another super-continent. </span>
