What is the pathway of food to the stomach?
Esophagus: The esophagus is a muscular tube that connects the pharynx (throat) to the stomach. The esophagus contracts as it moves food into the stomach. A “valve” called the lower esophageal sphincter (LES) is located just before the opening to the stomach.

The GI tract is a series of hollow organs joined in a long, twisting tube from the mouth to the anus. The hollow organs that make up the GI tract are the mouth, esophagus, stomach, small intestine, large intestine, and anus. The liver, pancreas, and gallbladder are the solid organs of the digestive system.

What are the parts of the digestive system?
The digestive system is made up of the following: 1 The mouth. Takes in food, breaks it into pieces, and begins the digestion process. 2 The esophagus. Moves food from the mouth to the stomach. 3 The stomach. Breaks food down into a liquid mixture. 4 The liver. Makes bile that helps digest fat. 5 The gallbladder. Stores bile. 6 The pancreas. Makes enzymes that help in digestion. 7 The small intestine. Digests food further and absorbs nutrients. What is left is passed on to the colon as liquid waste. 8 The large intestine (colon). Absorbs water, salt, and minerals from the waste, forming a solid stool. 9 The rectum. Stores stool until a bowel movement happens. 10 The anus. The opening where stool leaves the body.
What happens when food moves through the digestive system?
As food moves along the digestive tract, it is digested. This means it is changed into substances that can be absorbed into the bloodstream. Certain organs (such as the liver, gallbladder, and pancreas) help with this digestion. Parts of food that can't be digested are turned into stool.
Which system breaks food into pieces?
Digestive system. The digestive system is made up of the following: The mouth. Takes in food, breaks it into pieces, and begins the digestion process. The esophagus. Moves food from the mouth to the stomach. The stomach. Breaks food down into a liquid mixture. The liver.
Which organ breaks down food into liquid?
The stomach. Breaks food down into a liquid mixture.
Which organ absorbs water, salt, and minerals from waste?
Digests food further and absorbs nutrients. What is left is passed on to the colon as liquid waste. The large intestine (colon). Absorbs water, salt, and minerals from the waste, forming a solid stool. The rectum. Stores stool until a bowel movement happens. The anus.
Which organs release enzymes to digest food?
A variety of digestive juices released by liver, pancreas and gallbladder will enter your small intestine for complete digestion of food. Pancreas produces enzymes to break down carbohydrates, proteins and fats, whereas the liver produces bile to digest fats. The wall of your small intestine also secretes other juices for digestion.
Where does food go after digestion?
The wall of your small intestine also secretes other juices for digestion. The food will then move into the second section of your small intestine where it will turn into smaller molecules of nutrients. After that, it moves into the final portion of your small intestine where the remaining nutrients are absorbed.
How does the stomach break down food?
The digestive glands in your stomach will also produce enzymes and stomach acid. The combination of stomach acid and enzymes turn the food into a paste called chyme. Your stomach muscles will then contract to push the chyme towards your small intestine. The food will enter the small intestine through a valve called the pylorus. The pylorus releases a small amount of food at a time.
How does food enter the small intestine?
Your stomach muscles will then contract to push the chyme towards your small intestine. The food will enter the small intestine through a valve called the pylorus. The pylorus releases a small amount of food at a time.
How does the esophagus work?
It works in a systematic way – the muscles behind the round mass of food you have in the esophagus will contract to push it forward and the muscles ahead of it will relax to make it easy for your food to travel to your stomach.
What is the order of the digestive system?
What Is the Order of Digestive System? Your digestive system consists of the digestive tract – also called the gastrointestinal (GI) tract – and the liver, gallbladder and pancreas. The digestive tract is basically a series of hollow organs jointed in a twisting tube from the mouth all the way down to the anus.
What is the rectum?
The rectum is an 8-inch chamber connecting your colon to your anus. It receives stool form the colon and holds it until evacuation happens. That's everything about the order of digestive system, but if you still have questions or want to know more about organs in the digestive system, watch the following video: YouTube.
How long does it take for food to pass through the digestive system?
A look at the time it takes for food to pass through the gut from mouth to anus. In a healthy adult, transit time is about 24–72 hours. Read the article The human digestive system for further information.
How long does it take for the small intestine to absorb enzymes?
It takes 3–5 hours from entry to the duodenum to exit from the ileum. The small intestine ’s structure of folds, villi and microvilli increases the absorptive surface area and allows maximum exposure to enzymes and complete absorption of the end products of digestion.
What are the tiny structures that project inwards from the lining of the small intestine?
Millions of tiny finger-like structures called villi project inwards from the lining of the small intestine. The large surface area they present allows for rapid absorption of digestion products.
How long is the large intestine?
The large intestine is 1.5–1.8m in length and is divided into the caecum, colon and rectum. The colon is further divided into 4 parts – ascending colon, transverse colon, descending colon and sigmoid colon. Watch this video to find out more about the function of the large intestine.
How long does it take for food to swallow?
Involuntary muscle contractions in the pharynx then push the bolus down towards the oesophagus. This swallowing reflex takes about 1–3 seconds.
What are the functions of the large intestine?
The 4 major functions of the large intestine are recovery of water and electrolytes, formation and storage of faeces and fermentation of some of the indigestible food matter by bacteria.
What is the egestion of the rectum?
Egestion: Rectum. The rectum’s external opening, the anus, is controlled by a set of muscles. When filled by a mass movement from the sigmoid colon, the rectum is stretched and produces the desire to defecate. If inhibited, the urge to defecate subsides but returns several hours later.
