Biology is designed for multi-semester biology courses for science majors. It is grounded on an evolutionary basis and includes exciting features that highlight careers in the biological sciences and everyday applications of the concepts at hand. To meet the needs of today’s instructors and students, some content has been strategically condensed while maintaining the overall scope and coverage of traditional texts for this course. Instructors can customize the book, adapting it to the approach that works best in their classroom. Biology also includes an innovative art program that incorporates critical thinking and clicker questions to help students understand—and apply—key concepts.

By the end of this section, you will be able to:Explain the processes of digestion and absorptionCompare and contrast different types of digestive systemsExplain the specialized functions of the organs involved in processing food in the bodyDescribe the ways in which organs work together to digest food and absorb nutrients

This patient education program reviews the anatomy of the gallbladder, symptoms of gallstones, treatment options, and the benefits and risks of cholecystectomy. This is a MedlinePlus Interactive Health Tutorial from the National Library of Medicine, designed and developed by the Patient Education Institute.

The digestive system is amazing: it takes the foods we eat and breaks them into smaller components that our body can use for energy, cell repair and growth. This lesson introduces students to the main parts of the digestive system and how they interact. In addition, students learn about some of the challenges astronauts face when trying to eat in outer space.

The gall bladder stores bile produced in the liver. Bile is important in the digestion of lipids. The gall bladder forms as an outgrowth of the bile duct, as a secondary hollow at the posterior edge of the original hepatic rudiment. The cystic duct joins the common bile duct which enters the duodenum at the major duodenal papillae (with the pancreatic duct) on the dorsal surface of the duodenum.

This resource is a video abstract of a research paper created by Research Square on behalf of its authors. It provides a synopsis that's easy to understand, and can be used to introduce the topics it covers to students, researchers, and the general public. The video's transcript is also provided in full, with a portion provided below for preview:

"Gallbladder cancer (GBC) is becoming increasingly common, especially in American Indian and Southeast Asian populations. Early GBC can be successfully removed with surgery, but advanced GBC has a poor prognosis . and the existing treatments have many side effects. To explore better therapies, researchers recently investigated the anti-GBC effects of penfluridol, an antipsychotic drug with anticancer activity. In vitro, penfluridol (PF) strongly inhibited the replication and invasion of three GBC cell lines, confirming its anti-GBC potential, but it also dramatically increased glucose consumption via glycolysis, which is a hallmark of cancer. Specifically, penfluridol activated the AMPK/PFKFB3 glycolysis pathway. However, inhibiting glycolysis, particularly the AMPK/PFKFB3 pathway (with Compound C, CC) solved this problem enhancing penfluridol’s GBC-killing effects. The same synergistic effects were observed in mouse tumor models in vivo..."
