Class 8 Science Chapter 2 The Invisible Living World: Beyond Our Naked Eye Question Answer
Muscle cells lining the food pipe (oesophagus) are essential for moving food to the stomach. They contract rhythmically in a process called peristalsis, which propels the food downward. Without these cells, swallowing and digestion would be impossible. These muscle cells work involuntarily, meaning they operate without conscious effort, ensuring smooth and continuous movement of food through the digestive system.
