Answer:
The correct answer is - smooth muscles.
Step-by-step explanation:
inside the organs, there are internal muscles present that build walls of most of the organs like the stomach, heart, blood vessels, intestines, and more hollow organs. These muscles are composed of ininvoluntary muscles.
These muscles can not be controlled as these are meant to be working on their own with the stimulus. The role of such muscles is to push or pull the various material such as blood, or food through the organs.
Thus, the correct answer is - smooth.
