The cardia of the stomach is not a specific organ but a descriptive term for a location in the stomach. It is the first portion of the stomach, connecting the esophagus to the stomach. The cardioesophageal sphincter, or gastroesophageal sphincter, is contained within the cardia of the stomach.
The part of the stomach that is closest to the esophagus. Food and liquids pass through the cardia to enter the stomach from the esophagus. A valve near the cardia helps keep stomach contents from backing up into the esophagus.
The cardiac gastric glands are located at the very beginning of the stomach; the intermediate, or true, gastric glands in the central stomach areas; and the pyloric glands in the terminal stomach portion. Both the cardiac and pyloric glands secrete mucus, which coats the stomach and…
The key difference between cardiac and pyloric sphincter is that cardiac sphincter is present at the upper portion of the stomach and closes off the top end of the stomach while pyloric sphincter is present at the lower end of the stomach and closes off the bottom of the stomach.
The cardiac stomach of a crayfish is located in the anterior section of the animal, near the head. It is a muscular, sac-like organ that is mainly responsible for grinding up food before it is passed on to the rest of the digestive system.
The cardiac stomach is a chitinous, thin-walled translucid chamber, of greater volume than the pyloric stomach. It has a series of well calcified pieces on the walls symmetrically disposed at the posterior end (Figure 1).
Inside the cardiac stomach there is a teeth like structure that helps break up the food before it is sent to the digestive tract; which is a body part that acts like a liver and kidney. The other stomach, called the pyloric stomach, uses chemicals in this stomach to break down the food.
The cardia of the stomach is not a specific organ but a descriptive term for a location in the stomach. It is the first portion of the stomach, connecting the esophagus to the stomach.
Typically, gas causes bloating, burping, knotted stomach, and sharp pains that suddenly come and go. On the other hand, symptoms of a heart attack include cold sweat, palpitations, light-headedness, nausea or vomiting, pain in your upper body, arms, and shortness of breath.
The Merriam Webster New International Unabridged Dictionary can do no better than the others in stating that the word stems, "from Greek kardia, heart or upper orifice of the stomach." This source continues, "Anat. a. the opening of the esophagus into the stomach, b.
Stomach: It is a large sac-like organ that is situated behind the oesophagus. It is divided into two parts: the cardiac stomach and pyloric stomach. Cardiac Stomach: It is the anterior portion of the stomach. It has inner cuticular walls that are lined with minute bristles.
The pyloric sphincter at the bottom of the stomach governs the passage of food out of the stomach into the small intestine.
The cardia is the transitional region between the esophagus and body of the stomach. The pylorus is the narrow region that connects the stomach to the duodenum. The cardia and pylorus contain branched coiled tubular glands that secrete mucus.
Pain may extend downward into the belly area and may feel like heartburn. Shortness of breath. You may gasp for breath or try to take in deep breaths. This often occurs before any chest discomfort.
Right now, scientists believe one link has to do with the compounds gut bacteria produce when they break down certain foods. Having the wrong balance of bugs may mean more byproducts that raise cholesterol levels and harm blood vessels.
Stomach pain or indigestion
An indigestion-type pain or a burning sensation in your chest or stomach can be a sign of a heart attack or related heart problem.
Both heartburn and heart attack can cause intense feelings in the chest. One significant difference is that a heart attack usually feels like pressure, tightness or squeezing—rather than pain. The feeling may radiate up toward the left shoulder, arm and neck.
Burping can occur with stomach pain after eating certain foods or eating too quickly. It can also indicate an underlying condition, such as gastroesophageal reflux disease (GERD). Gas results either from swallowing air or as a byproduct of the breakdown of food in the large intestine.
Sometimes, these symptoms are hard to sense, and hence the two conditions become indistinguishable. You can know whether you are suffering from gastritis or having a heart attack by observing the symptoms. The burning sensation caused by gastritis starts from the upper part of the stomach.
The hydrochloric acid in the gastric juice breaks down the food and the digestive enzymes split up the proteins. The acidic gastric juice also kills bacteria.
The results of this study support the concept that the gastric cardia is present from birth as a normal structure, although it does not preclude the pos- sibility that cardiac-type mucosa can arise in the distal esophagus as a metaplastic phenomenon.
Crayfish: Unusual And Efficient Digestion
crayfish, on the other hand, have evolved to have a three-pronged organ known as their gastric mill, which consists of three large teeth that attach to their stomachs. Crayfish adapted to this unique diet to grind their food at an accelerated rate before digestion.
In starfishes the cardiac stomach is connected to a pyloric stomach which is located above it. Food can be brought into the stomach through the mouth or, in many species, the cardiac stomach can be extended out through the mouth to digest food outside the body.
The gut of the crayfish is divided into five parts: esophagus, large cardiac stomach (Fig. 3A and 3C), smaller pyloric stomach (Fig. 3B), midgut (intestine) and hindgut (rectum). The esophagus was not identified in this study.
