Stomach

organs of the digestive system, specifically the stomach, liver, duodenum and ileum, explain in detail the process that happens there. To give a more in-depth look at absorption it will explain the function of lacteals and capillaries…

digestive system is not the same in all organisms-in fact, there are four types of digestive systems. The most common digestive system is the monogastric digestive system. The monogastric digestive system occurs in organisms with a single-chambered stomach. Organisms such as pigs and humans have the monogastric digestive system. The second type of digestive system is the avian digestive system. The avian digestive system usually occurs in bird such as chicken. This digestive system is…

opening allows chyme to enter into the small intestine. The small intestine is composed of 3 parts: duodenum, jejunum and ileum. The duodenum is the only part of the small intestine that continues to break down food with the release of bile. While the stomach releases hydrochloric acid and creates an acidic environment with a low pH, the duodenum is slightly basic with a higher pH. Bile, which is produced in the liver and stored in large quantities in the gall bladder, is released to emulsify…

What is the issue being addressed? When food is swallowed it enters oesophagus – carrying food from the mouth to the stomach for further digestion. Contractions called peristalsis push the food down the oesophagus through a muscular valve called the lower oesophageal sphincter (LES) and into the stomach. The digestive juices secreted by the stomach are highly acidic. When the stomach contracts to move the food into the intestine the LES closes tightly in order to prevent these acidic juices from…

closed prevents acid and stomach contents from traveling backwards. Stomach- The stomach receives food from the esophagus and strong acids help break the food down. A lining of mucus protects the stomach from digesting itself and the stomach also stirs the acid-food mixture. Then the pyloric sphincter opens to allow food to pass from the stomach to the small intestine. Duodenum- The duodenum connects the stomach to the small intestine. Partially digested food from the stomach gets digested…

The small intestine consists of three divisions: The duodenum is the uppermost division and the part to which the pyloric end of the stomach attaches. it is about 25 cm (10 inches) long and is shaped roughly like the letter C. The name duodenum , meaning " 12 fingerbreadths," refers to the short length of this intestinal division. The duodenum becomes jejunum at the point where the tube turns abruptly forward and downward . The jejunal portion continues for approximately the next 2.5 m (8…

Prilosec (omeprazole), a proton pump inhibitor that reduces the amount of acid produced in the stomach in conditions caused by excess stomach acid. Prilosec suppresses gastric acid secretion by target inhibition of the H+/K+ ATPase enzyme system at the secretory surface of the gastric parietal cell. This enzyme system is considered as the acid (proton) pump within the gastric mucosa, Prilosec has been characterized as a gastric acid-pump inhibitor, because it blocks the final step of acid…

nasal cavity passes through the pharynx on its way to the larynx and eventually the lungs, because the pharynx serves two separate jobs. The esophagus is a really simple tube that is used for transportation starting at the mouth continuing to the stomach. In reality when we actually swallow what we are truly doing is closing a “trapped door” in the throat that is called the epiglottis. This is what sends food to the esophagus and this is what doesn’t let the food go down to the trachea and into…

swallowing to prevent choking. The trachea is the air conducting tube that connects to the lungs in order to breathe. The bolus of food is involuntarily pushed through the esophagus into the stomach by peristaltic contractions made by the muscles. The esophageal sphincter located between the esophagus and stomach acts as a regulator for what flows into the…

The digestive system is a group of organs that convert food into energy to feed the entire body. The alimentary is made up of the pharynx, esophagus, stomach, small intestines, and large intestines. Organs of the digestive system include the teeth, tongue, salivary glands, liver, gallbladder, and pancreas. In the digestive system it all begins with the mouth. Inside the mouth are many organs that help the food to be chopped up and swallowed . Teeth chop food into small pieces, which are…
