The organs and ducts that make up the Biliary System are bile ducts, and the gallbladder. In the system once the bile is secreted from the liver and drained through the smile bile bones called canaliculli. They collect into the heapatic ducts, which then collect in the common heapatic ducts. The heapatic ducts join by the cystic duct to create the common bile duct. These would run from the liver to the duodenum, which would be the first section of the small intestine. However, not all the bile flows directly into the duodenum. About half of the bile that is produced by the liver is stored in the gallbladder first. When food is eaten the gallbladder would contract and release the bile that was stored into the duodenum to help …show more content…
It is located under the diaphragm in the upper right abdomen and reaches the left upper abdomen. (1) The liver is made up of two parts the Parenchyma and Stroma. The main functions of the liver are metabolism, vascular functions and secretory and excretory functions. The liver breaks down carbohydrates, fats and proteins. The end products are mostly stored in the liver and then used later when the body requires them. (2) The Vascular Functions is the formation of lymph and digestion of old red blood cells. The secretory and excretory functions include the synthesis and secretion of bile. (3) There are two main cells that are found in the liver which are Kupffer cells and hepatocytes however there are others which are Stellate cells, Endothelial cells and …show more content…
Staining helps identify the different structures within the tissues; also it allows distinctions to be made between them. Most dyes have an acidic or basic compound. The tissue components that mostly stain with the basic dyes are called basophilic, on the other hand the structures that mostly die with acidic dyes are known as acidophilic structures. (6)
An example of an acidophilic dye is Eosin, which is a negative dye that attracts positive components. Hematoxiylin is an example of a Basic dye that is a positively charged dye and stains negative components blue. Hematoxylin and Eosin are commonly used together as one is a basic dye and the other is an acidophilic dye. H&E staining is the method is the most common technique that is used during animal histology and routine pathology. When an animal cell is died the Nuclei, Ribosomes and rough endoplasmic reticulum have a strong attraction for the dye due to their being a high number of DNA and RNA in the cells. On the other hand, Eosin, which is an acidic dye, stains the basic structured red or pink. Cytoplasmic proteins are basic therefor they stains pink.
