Human digestion

Digestive System Anatomy Mouth Food begins its journey through the digestive system in the mouth, also known as the oral cavity. Inside the mouth are many accessory organs that aid in the digestion of food—the tongue, teeth, and salivary glands.

Bacteria in the large intestine can also break down food. How does food move through my GI tract? Food moves through your GI tract by a process called peristalsis.

The large, hollow organs of your GI tract contain a layer of muscle that enables their walls to move. The movement pushes food and liquid through your GI tract and mixes the contents within each organ. The muscle behind the food contracts and squeezes the food forward, while the muscle in front of the food relaxes to allow the food Human digestion move.

The digestive process starts when you put food in your mouth. Food starts to move through your GI tract when you eat. When you swallow, your tongue pushes the food into your throat. A small flap of tissue, called the epiglottis, folds over your windpipe to prevent choking and the food passes into your esophagus.

Once you begin swallowing, the process becomes automatic. Your brain signals the muscles of the esophagus and peristalsis begins. When food reaches the end of your esophagus, a ringlike muscle—called the lower esophageal sphincter —relaxes and lets food pass into your stomach.

After food enters your stomach, the stomach muscles mix the food and liquid with digestive juices. The stomach slowly empties its contents, called chymeinto your small intestine. The muscles of the small intestine mix food with digestive juices from the pancreas, liver, and intestine, and push the mixture forward for further digestion.

The walls of the small intestine absorb water and the digested nutrients into your bloodstream.

Digestive System Diagram Digestion is the process of turning large pieces of food into its component chemicals. Mechanical digestion is the physical breakdown of large . The human digestive system is a series of organs that converts food into essential nutrients that are absorbed into the body and eliminates unused waste material. It is essential to good health. The human digestive system is a series of organs that converts food into essential nutrients that are absorbed into the body and eliminates unused waste material.

As peristalsis continues, the waste products of the digestive process move into the large intestine. Waste products from the digestive process include undigested parts of food, fluid, and older cells from the lining of your GI tract. The large intestine absorbs water and changes the waste from liquid into stool.

Peristalsis helps move the stool into your rectum. The lower end of your large intestine, the rectum, stores stool until it pushes stool out of your anus during a bowel movement.

How does my digestive system break food into small parts my body can use? As food moves through your GI tract, your digestive organs break the food into smaller parts using: The digestive process starts in your mouth when you chew.

Your salivary glands make salivaa digestive juice, which moistens food so it moves more easily through your esophagus into your stomach. Saliva also has an enzyme that begins to break down starches in your food.

After you swallow, peristalsis pushes the food down your esophagus into your stomach. Glands in your stomach lining make stomach acid and enzymes that break down food.

Muscles of your stomach mix the food with these digestive juices. Your pancreas makes a digestive juice that has enzymes that break down carbohydrates, fats, and proteins. The pancreas delivers the digestive juice to the small intestine through small tubes called ducts. Your liver makes a digestive juice called bile that helps digest fats and some vitamins.

Bile ducts carry bile from your liver to your gallbladder for storage, or to the small intestine for use. Your gallbladder stores bile between meals.

Human digestion

When you eat, your gallbladder squeezes bile through the bile ducts into your small intestine. Your small intestine makes digestive juice, which mixes with bile and pancreatic juice to complete the breakdown of proteins, carbohydrates, and fats. Bacteria in your small intestine make some of the enzymes you need to digest carbohydrates.

Your small intestine moves water from your bloodstream into your GI tract to help break down food. Your small intestine also absorbs water with other nutrients.

In your large intestine, more water moves from your GI tract into your bloodstream. Bacteria in your large intestine help break down remaining nutrients and make vitamin K.

Waste products of digestion, including parts of food that are still too large, become stool. What happens to the digested food?Digestion is the complex process of turning the food you eat into nutrients, which the body uses for energy, growth and cell repair needed to survive.

The digestion process also involves creating. The human digestive system is a series of organs that converts food into essential nutrients that are absorbed into the body and eliminates unused waste material. It is essential to good health. Human digestive system.

The food we eat has to be broken down into other substances that our bodies can use. This is called digestion.

Crash Course Biology is now available on DVD! And the digestive system will be busy at work on your chewed-up lunch for the next few hours — or sometimes days, depending upon what you've eaten.

This process, called digestion, allows your body to get the nutrients and energy it needs from the food you eat.
