Our body cells cannot use the food in the form it is eaten by us. Our body changes it into simpler form. The process of changing the food into simpler form is called digestion. The parts of body that take part in the process of digestion form the digestive system. <figure class="wp-block-image size-full"><img src="https://www.primacyebooks.com/wp-content/uploads/2024/09/Digestive-system.png" alt="Digestive system" class="wp-image-20950"/></figure> <div class="sign-up-notice-after-excerpt-two" style="background-color:powderblue;"> You are viewing an excerpt of this lesson.
