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

"A new study published in the journal Anesthesiology suggests that computer-assisted individualized hemodynamic management is a promising strategy to minimize hypotension during certain surgeries. Intraoperative hypotension is common but can increase the risk of postoperative complications. During surgery, individualized hemodynamic management can help mitigate hypotension and decrease such complications. In this strategy, clinicians use both intravenous fluids and vasopressors to maintain mean arterial pressure and blood volume near a patient’s personalized baseline. Despite its reported success, this approach requires constant monitoring and adjustment, which can be particularly challenging during complex and prolonged surgeries. Automated systems that can deliver either vasopressors or fluids have recently been developed, but a single closed-loop system that can deliver both with minimal clinician intervention isn’t yet available..."

"Oropharyngeal dysphagia is characterized by difficulty swallowing and occurs in about 45% of stroke patients. Thickening agents are one effective way to help patients with dysphagia consume liquids and foods. However, few viscosity levels per study have been assessed, and the optimal levels for patients with oropharyngeal dysphagia have not yet been established. To address that gap, the Physiology Digestive team from the Hospital of Mataró recently tested Nutilis Clear®, a xanthan gum-based thickener, at 7 shear viscosity levels. They looked at the effects of viscosity on the safety, efficacy, and physiology of swallowing in patients with post-stroke oropharyngeal dysphagia. The researchers first provided patients a thin liquid, followed by thickened boluses, from the highest to the lowest. Each bolus was provided in duplicate..."
