What are the steps of protein digestion?
Once a protein source reaches your stomach, hydrochloric acid and enzymes called proteases break it down into smaller chains of amino acids. Amino acids are joined together by peptides, which are broken by proteases. From your stomach, these smaller chains of amino acids move into your small intestine.
What are the 4 steps of digestion in order?
There are four steps in the digestion process: ingestion, the mechanical and chemical breakdown of food, nutrient absorption, and elimination of indigestible food.
What are the 7 steps of digestion?
Figure 2: The digestive processes are ingestion, propulsion, mechanical digestion, chemical digestion, absorption, and defecation. Some chemical digestion occurs in the mouth. Some absorption can occur in the mouth and stomach, for example, alcohol and aspirin.
What are the 6 steps of digestion?
The six major activities of the digestive system are ingestion, propulsion, mechanical breakdown, chemical digestion, absorption, and elimination. First, food is ingested, chewed, and swallowed.
What are the 4 main functions of the digestive system?
Motility, digestion, absorption and secretion are the four vital functions of the digestive system. The digestive system breaks down the foods we eat into energy our bodies can use.
What is the process of food digestion?
Digestion works by moving food through the GI tract. Digestion begins in the mouth with chewing and ends in the small intestine. As food passes through the GI tract, it mixes with digestive juices, causing large molecules of food to break down into smaller molecules.
What are the 3 stages of digestion?
Gastric activity involved in digestion is divided into three stages known as the cephalic phase, the gastric phase, and the intestinal phase. These phases overlap and all three can occur simultaneously.
What are the 5 main components of the digestive system?
The main organs that make up the digestive system (in order of their function) are the mouth, esophagus, stomach, small intestine, large intestine, rectum and anus.
