APPLIED RADIOLOGICAL ANATOMY

Detailed explanation-1: -Answer. Smooth muscle is responsible for carries out most of the involuntary processes such as digestion as well as pumping the blood through arteries. Therefore, option 2 is the right answer. Carries out most of the involuntary processes such as digestion as well as pumping the blood through arteries.

Detailed explanation-2: -In the cardiovascular system, smooth muscle is used in vessels to maintain blood pressure and flow; in the lungs, it opens and closes airways; in the gastrointestinal system it plays a role in motility and nutrition collection; and yet it still serves a purpose in almost every other organ system as well.

Detailed explanation-3: -Structure and Function Smooth muscle differs from skeletal muscle in function. Unlike skeletal muscle, smooth muscle is capable of maintaining tone for extended periods and often contracts involuntarily. At a cellular level, smooth muscle can be described as an involuntary, non-striated muscle.

Detailed explanation-4: -Smooth muscle, found in the walls of the hollow internal organs such as blood vessels, the gastrointestinal tract, bladder, and uterus, is under control of the autonomic nervous system. Smooth muscle cannot be controlled consciously and thus acts involuntarily.

Detailed explanation-5: -An example of involuntary muscle movement controlled by smooth muscles is peristalsis, or the contraction of digestive muscles throughout the organs and from one organ to another.
