How your body turns food into the poo Human digestion system With Narration #inside_the_intestine How does your body turn food into poop? Mechanical digestion begins in the mouth as the food is chewed. Chemical digestion begins in the mouth when food mixes with saliva. Saliva contains an enzyme (amylase) that begins the breakdown of carbohydrates. The epiglottis is a flexible flap at the end of the larynx in the throat. It acts as a switch between the larynx and the esophagus to permit air to enter the airway to the lungs and food to pass into the esophagus. it is a muscular tube connecting the throat with the stomach. The esophagus is about 8 inches long. The esophagus muscle acts with peristaltic action to move swallowed food down to the stomach. The action of peristalsis looks like an ocean wave moving through the muscle The food then enters the stomach, which is a rounded, hollow j shape organ Located between the esophagus and the duodenum. the stomach has three mechanical tasks to do. First, the stomach must store the swallowed food and liquid. This requires the muscle of the upper part of the stomach to relax and accept large volumes of swallowed material., The inner layer of the stomach is full of wrinkles known as rugae. Rugae both allow the stomach to stretch in order to accommodate large meals and help to grip and move food during digestion. The second job is to mix up the food, liquid, with digestive juice produced by the stomach. The lower part of the stomach mixes these materials as a blender by its muscle action. and breaks down the food into tiny particles in 3 millimeters finally, the stomach empties this acidy mash slowly into the small intestine. The small intestine or small bowel is an organ in the gastrointestinal tract where most of the end absorption of nutrients and minerals from food takes place. It lies between the stomach and large intestine and receives bile and pancreatic juice through the pancreatic duct to aid in digestion. The Duodenum, the first part of the small intestine, receives partially digested food from the stomach and begins the absorption of nutrients. The duodenum is the shortest segment of the intestine and is about 23 to 28 cm (9 to 11 inches) long. It is roughly horseshoe-shaped The pancreatic juices and bile that are released into the duodenum, help the body to digest fats, carbohydrates, and proteins. The food is in instetin now and has a very long way to go! As a person grows the small intestine increases 20 times in length from about 200 cm in a newborn to almost 6 m in an adult. The inner walls of the small intestine show mucosal folds. These are called the plicae circulares. The plicae are more numerous in the early and reduce in numbers in the later part and are completely absent. Digestion is important because your body needs nutrients from food and drink to work properly and stay healthy. Proteins, fats, carbohydrates, vitamins, minerals, and water are nutrients. Your digestive system breaks nutrients into parts small enough for your body to absorb and use for energy, growth, and cell repair. •Proteins break into amino acids •Fats break into fatty acids and glycerol •Carbohydrates break into simple sugars In the small bowel, the food particles get even smaller. Here is where all the important vitamins and nutrients in food move through the blood vessels that are in the lining of the small bowel. The blood takes the nutrients to other organs in the body. The nutrients are used to help repair cells and tissue. What is left over, which is mostly liquid, then moves into the colon. The water is absorbed in the colon. Bacteria in the colon break down the remaining material. Then the colon moves the leftover material into the rectum. the rectum is like a storage-holder for this waste. Muscles in the rectum move the waste, called stool, out of the body through the anus. 0:01 How does your body turn food into the poo 0:08 food in the mouth 0:34 Esophagus 0:52 Stomach 1:56 Small intestine 3:35 Colon 3:60 Rectum #3dmedicalanimation Small intestine with intestinal worms 360 degree Intestinal Parasites medical animation The effect of Tied umbilical cord in twins High Blood Pressure Hypertension How your body turns food into the poo Human digestion system in human beings coronary angiogram Micro Needle|3d medical animation|sample use only heart valve replacement 3d medical animation|sample use only|dandelion team shortvideos how long does it take for the body to digest food?
