Amphibian Internal Anatomy Labelled parts: Right atrium, Left atrium, Ventricle, Liver, Kidney, Small intestine, Large intestine, Cloaca, Lung, Gall bladder, Stomach, Pancreas, Spleen, Fat bodies, Testis, Ureter, Urinary bladder. This small organ stores and concentrates bile, which is produced by the liver. Bile is essential for the digestion and absorption of fats and fat-soluble vitamins. FYI: The bile stored in the gall bladder is alkaline and contains bile salts, which emulsify large fat globules into smaller droplets. The spleen is a major lymphatic organ that filters blood, removing old or damaged blood cells and filtering out pathogens. It is a key site for immune response. FYI: The spleen is particularly important for the immune response against encapsulated bacteria and is where red blood cells are cleared (culling). These are specialized tissues found in invertebrates (like insects) that serve as storage organs. They store excess nutrients, including lipids (fats) and glycogen. FYI: In insects, the fat body is analogous to the liver and adipose tissue in vertebrates, playing roles in metabolism and detoxification. This is a tube that transports urine from the kidney (specifically, the renal pelvis) down to the urinary bladder. It is lined with smooth muscle. FYI: Urine flow through the ureter is maintained by peristaltic contractions of the smooth muscle layer, ensuring unidirectional movement.
