Esophagus

DOES IT MEAN? Heartburn does not literally mean a burning heart. It is a painful, awkward and an uncomfortable symptom that occurs when the acid in the stomach goes to the esophagus near the chest. Heartburn is the consequence of either excessive or poor quality food intake, which then causes the rising of acids to the esophagus. It is a typical occurrence even the healthiest people may experience this condition. SYMPTOMS The general symptom of heartburn is a burning feeling in the chest, which…

of peristalsis, of the esophagus. LES pressure and relaxation are regulated by excitatory and inhibitory neurotransmitters however, patients with achalasia lack these nonadrenergic, noncholinergic inhibitory ganglion cells thus, causing imbalance between the excitatory and inhibitory processes of neurotransmitters resulting to a hypertensive nonrelaxed esophageal sphincter. The cause of achalasia is unknown however, there can be degeneration of the muscles of the esophagus and the nerves that…

numerous substances. It is often described as a long muscular tube starting at the mouth, and ending at the anus. The esophagus, stomach, small intestine (consisting of the duodenum, jejunum, and the ileum), and the large intestine (consisting of the cecum, ascending, transverse, and descending colon, the sigmoid, rectum, and anus), all make up the gastrointestinal tract. The esophagus is the starting point for the gastrointestinal tract, it is a muscular tube that measures approximately…

the bread to form a bolus of food. This Bolus of food is pushed between the hard palate and the tongue mixing the bolus of food with saliva and pushing the bolus of food from the mouth into the esophagus, this is called swallowing. The bolus of food leaves the amount past the pharynx enters into the esophagus, this is a muscular tube that connects the mouth to the stomach. There is a sphincter at the upper…

mucosa that lines the stomach is able to resist the juices of the stomach acid. What are sphincters and how are they related to the stomach? The first is the cardiac sphincter located at the top of the stomach, separating the stomach from the esophagus. The second is the lilac sphincter, at the bottom of the stomach separating the small intestines from the stomach. The two sphincters regulate how much goes in and out of the stomach. What mechanical and chemical digestion occurs in the…

the upper side of the stomach gets in the chest through an opening in the diaphragm called the hiatus. The diaphragm is the muscle that separates the thoracic cavity from the abdomen, and the hiatus is an orifice in the diaphragm through which the esophagus passes in order to reach the stomach. When hiatal hernia appears,…

In this phase, solid is placed into the mouth and the lips are shut by the orbicularis oris facial muscle (VII). The food is mixed with salvia and masticated with the teeth, so it can pass through the esophagus for digestion. Sensory recognition is critical at this stage and the movement and timing patterns in this phase varies depending on the viscosity. The salvia and food has now created a bolus in which lateral movements of the tongue and mandible are made. Furthermore, the soft palate has…

found on both sides of the heart and underneath the rib cage. The lungs help with oxygenation, so they are part of the respiratory system. Esophagus: The esophagus is in charge of bringing food down from the mouth and leading it to the stomach. It is located in the thoracic cavity underneath the trachea and appears much less firm than the trachea. The esophagus belongs to the digestive…

one, which can occur just from having a large hiatus, they may feel food and acid refluxing into the esophagus which can cause heartburn. Sometimes over the counter antacids will be enough…

organs are the pharynx, esophagus, stomach, small intestines, and large intestines. The accessory organs are the liver, gallbladder, and pancreas. The same organs are found in the fetal pig as well. The pharynx, also known as the throat, is a muscular tunnel that extends from the nose to the esophagus. It serves as a pathway for food traveling from the mouth to the esophagus. The esophagus is a long, thin, and muscular tube that connects the pharynx to the stomach. The esophagus acts a…
