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

By the end of this section, you will be able to:Describe the role of different glands in the endocrine systemExplain how the different glands work together to maintain homeostasis

This presentation provides an introduction to Diabetes.What is diabetes and what happens in the body? You will learn how diabetes is a term used to describe the body’s inability to produce sufficient amounts of insulin and how insulin as a pancreatic hormone functions as a main glucose regulator, that makes sure our glucose levels are balanced. Both high and low blood glucose levels are dangerous. When you have diabetes, the lack of insulin will cause high blood glucose levels, which affects several parts of your body.

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 most recent knowledge of the anatomy, physiology, biochemistry, biophysics, and bioengineering of the gastrointestinal tract and the associated pancreatic, liver and biliary tract systems is presented and discussed. Gross and microscopic pathology and the clinical aspects of important gastroenterological diseases are then presented, with emphasis on integrating the molecular, cellular and pathophysiological aspects of the disease processes to their related symptoms and signs.

The pancreas is a tubuloalveolar gland and has exocrine and endocrine tissues. The exocrine is the larger of the two parts and secretes pancreatic juice; a solution containing enzymes for carbohydrate, protein and triacylglycerol digestion. Pancreatic juice drains into the small intestine where it is functional. The endocrine part secretes hormones for the regulation of blood glucose concentration, including insulin, glucagon and somatostatin. The functional units of the endocrine part are the islets of Langerhans.

This patient education program discusses both acute and chronic pancreatitis, including causes, symptoms, diagnosis, and treatment options. It also reviews the anatomy of the digestive system. This resource is a MedlinePlus Interactive Health Tutorial from the National Library of Medicine, designed and developed by the Patient Education Institute.

Psychology is designed to meet scope and sequence requirements for the single-semester introduction to psychology course. The book offers a comprehensive treatment of core concepts, grounded in both classic studies and current and emerging research. The text also includes coverage of the DSM-5 in examinations of psychological disorders. Psychology incorporates discussions that reflect the diversity within the discipline, as well as the diversity of cultures and communities across the globe.Senior Contributing AuthorsRose M.

By the end of this section, you will be able to:Identify the major glands of the endocrine systemIdentify the hormones secreted by each glandDescribe each hormone’s role in regulating bodily functions

Students consider human senses and the many everyday human-made sensors so common in their lives. They learn about the three components of biosensors—a special type of sensor—and their functions and importance. With this understanding, students identify various organs in the human body that behave as sensors, such as the pancreas. Using LEGO® MINDSTORMS® NXT robots, provided rbt robot programs and LEGO sensors (light, ultrasonic, sound, touch), students gain first-hand experience with sensors and come to see how engineer-designed sensors play important roles in our daily lives, informing people of their surroundings and ultimately improving our quality of life.

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:

"Advancements in next-generation sequencing have opened the door to detailed analyses of the human microbiome. This technique has many applications, and pancreatic cancer research is one of them. Pancreatic cancer is a devastating disease with an estimated 5-year survival rate of only 11%. Most cases, over 80%, are not found until the cancer is too advanced to successfully treat, but pancreatic cancer patients show shifts in their oral microbiome, which could be detected years earlier than current methods allow. Pathogenic oral bacteria have also been found within pancreatic tumors, which is another potential link between them. However, these findings barely scratch the surface of how the oral microbiome relates to pancreatic cancer. The oral microbiome is influenced by a combination of host-related and environmental factors, which include genetics, race, ethnicity, smoking, socioeconomics, and age..."
