Gallbladder Essay

The gallbladder is inferior and posterior to the liver. The gallbladder and its connecting ducts are referred as the biliary system. The biliary system is involved in the production and transportation of bile2. Bile is produced in the liver and when it is secreted, it flows through the cystic duct to the gallbladder to be stored. The gallbladder is a storage unit for bile. The job of bile is to emulsify fat. Also in the gallbladder, hard deposits of bile can form. Those hard deposits are called gallstones and they can be quite painful.

The pain that Ms. Martha is feeling is because of those gallstones. It is blocking the drainage system of the gallbladder. If the gallstone was to get dislodged, it would travel through the cystic duct and out

through the major duodenal papilla, entering the duodenum. From the duodenum, the gallstone will travel through the jejunum and ileum, both of which help make up the small intestine. From the ileum, the gallstone enters the beginning of the large intestine which is the cecum. From the cecum, the gallstones can take two paths. One path travels through the large intestine to the rectum, then through the anal canal, and finally ending up in the toilet. The second path is more life threatening since the gallstone can enter the cecum and drop to the bottom of it, blocking the hole of the appendix. If the appendix is blocked, that blockage can lead to appendicitis, which is the inflammation of the appendix.
She’s has referred pain which is pain perceived at a location different from the pain stimulus. Although she has pain in her gallbladder area, she also has referred pain in wrapped her back, inferiorly to her scapula.
The liver and biliary system is innervated by the celiac plexus which is connected to the greater splanchnic nerves. The greater splanchnic nerves innervate T5 through T8 of the spine. The preganglionic fibers of the greater splanchnic nerves pass through the sympathetic chain without synapsing and enter through the celiac ganglion and synapses. From the celiac ganglion, the postganglionic fibers head to and innervates the liver and biliary system. This
When the surgeon performs the surgery to remove the gallbladder, the cystic artery must be ligated or closed off. The cystic artery supplies the blood to the gallbladder. The right atrium supplies the numerous arteries that supply the cystic artery.
The pathway of blood from the right atrium of the heart to the gallbladder isn’t as difficult as it seems.

It begins at the right atrium. Blood enters the right atrium from the superior and inferior vena cava and the coronary sinus, then it moves through the tricuspid valve. After the tricuspid valve, blood enters the right ventricle which then leads to another valve called the pulmonary semilunar valve. From the pulmonary semilunar valve, blood enters the pulmonary trunk which branches off into the right and left pulmonary arteries. From the pulmonary arteries, the blood enters the lungs and undergoes a gas exchange in the alveoli. After gas exchange has occurred, oxygenated blood flows through the pulmonary veins into the left atrium. From the left atrium, blood runs through the bicuspid valve. From the bicuspid valve, the blood enters the left ventricle and is pumped through a fourth valve, the aortic semilunar valve, and courses through the aortic arch. From the aortic arch, the blood rushes down the descending aorta and runs through the celiac trunk. Said trunk branches off into 3 arteries, one being the common hepatic artery. From the common hepatic artery, blood branches off to the right hepatic and cystic arteries. It is the latter that ultimately supplies the

gallbladder.
