The smooth muscles in the walls of the digestive system contract to keep food moving through the alimentary canal. In the small intestine, there are circular and longitudinal muscles which together produce the pinching and squeezing movement we call peristalsis.
The heart itself is made of muscle, a special kind called cardiac muscle, and its contractions are what pushes the blood around.
peristalsis
Both are controlled involuntarily - you don't have to consciously think to keep your heart beating or to have your intestine move food toward your colon.
Involuntary muscles perform the work of internal organs. In the case of the digestive tract, peristaltic muscles are smooth muscle that surrounds the intestines; the heart uses cardiac muscle, a special kind of striated muscle.
The autonomic system controls bodily functions that are in constant motion without the conscious mind aware of it, such as food digestion and heart beating. It has nothing to do with gender preferences.
beating as it would normally
Smooth muscles are found in the intestines and stomach. If these were skeletal muscles, instead of smooth, you would have to physically think about digesting your food to control digestion, and no food would get digested while you were busy or sleeping!it is the smooth muscles only.Smooth muscle
Peristalsis - the moving of food along through the digestive system.
Digestive organs
Digestion is with food turning into waste, associated with stomach.Circulatory is with blood circulating through the body, associated with heart its also a cycle.
Smooth muscle contractions account for the movement of food along the digestive tract.
heart to the lungs
It takes food from the throat and pushes it down through the neck, and into the stomach. It moves food by waves of muscle contraction called peristalsis.
The heart contains cardiac muscle. This muscle is involuntary, like smooth muscle, but is made up of different types of cells from food muscle.
