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).

Hormones play important roles in
regulating blood glucose levels. For example, (i) the hormone insulin regulate
blood glucose levels by suppressing the breakdown of proteins into amino acids and
of adipose tissue into free fatty acids. (ii) The hormone asprosin regulate
blood glucose levels by enhancing the release of liver glucose during fasting.
Answer:
And over time, volcanoes made from low lava viscosity are wide and have a shallow slope; these are known as shield volcanoes. Classic examples of shield volcanoes are Mauna Kea and Mauna Loa in Hawaii, as well as Olympus Mons on Mars. When lava has a high viscosity, it's very thick and doesn't flow very well at all.
9,600 cubic miles
Mauna Loa is the largest volcano on Earth with an estimated volume of 9,600 cubic miles (40,000 cubic kilometers). It makes half of the area of the Island of Hawaii. Mauna Loa began to form nearly a million years ago. There is a caldera, Mokuaweoweo, at the summit and rift zones extend to the northeast and southwest.
