According to Locust Valley Central School District, the carbon dioxide-oxygen cycle is the process through which carbon dioxide and oxygen move through the natural environment by photosynthesis, respiration, combustion and decomposition. Plants and animals are important to the carbon dioxide-oxygen cycle. Keep Learning.
What is cholecystitis? Cholecystitis is inflammation of the gallbladder, a small organ near the liver that plays a part in digesting food. Normally, fluid called bile passes out of the gallbladder on its way to the small intestine. If the flow of bile is blocked, it builds up inside the gallbladder, causing swelling, pain, and possible infection. What causes cholecystitis? A gallstone stuck in the cystic duct, a tube that carries bile from the gallbladder, is most often the cause of sudden (acute) cholecystitis. The gallstone blocks fluid from passing out of the gallbladder.
Acute acalculous cholecystitis (ACC) is a rare complication of acute viral hepatitis [2]. Although the origin is obscure, demonstrated invasion of the gallbladder and bile duct epithelium by HAV and cell-mediated immunologic response have been proposed in the pathogenesis of HAV infection induced cholecystitis [3, 4].
