Digestion Process

• Digestion Process-begins from the mouth and ends in the small intestine – the large intestines’ main function is to absorb the remaining water from the undigested food and enable bacterial fermentation of materials that can no longer be digested.
• There are 6 types of Digestion Process in the digestive System
• Ingestion-very first step involves mastication (chewing)
• Ingestion- The salivary glands, along with the tongue, helps to moisten and lubricate food, before being pushed down into the food pipe.
• Mixing and Movement -lubricating and manipulating food and pushing it down the food through the food pipe (using peristalsis), and into the stomach.
• Secretion-The stomach, small intestine, liver, and pancreas secrete enzymes and acids to aid the process of digestion.
• Secretion-It functions by breaking down food particles into simple components and easily absorbable components.
• Digestion-converting complex food particles into simpler substances in the presence of enzymes and acids secreted by different digestive organs.
• Absorption-begins in the small intestine where most of the nutrients and minerals are absorbed. The excess water in the indigestible matter is absorbed by the large intestines.
• Excretion-removing indigestible substances and waste by-products from the body through the process of defecation.
