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.

Different hormones, neurotransmitters and reflexes are involved in the complicated process of feeding in animals. Secretions and motility of the gastrointestinal tract are stimulated and carefully regulated by numerous factors, including environmental stimuli and the presence of food in different parts of the gastrointestinal tract from the oral cavity right through to the intestines. When a harmful substance is ingested the body acts to eliminate it in different ways to prevent the animal becoming ill, for example, through vomiting and diarrhoea. If one or more of the pathways in controlling feeding is damaged or inhibited, then problems such as obesity occurs.
To reinforce students' understanding of the human digestion process, the functions of …
To reinforce students' understanding of the human digestion process, the functions of several stomach and small intestine fluids are analyzed, and the concept of simulation is introduced through a short, introductory demonstration of how these fluids work. Students learn what simulation means and how it relates to the engineering process, particularly in biomedical engineering. The teacher demo requires vinegar, baking soda, water and aspirin.

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.

After studying the basics of enzyme function, students will be exposed to the history and evolution of lactose intolerance/lactase persistence. Both whole group and individual activities will ask students to interact with the concept. They will conduct a lab to understand the role of enzymes in lactose digestion and communicate their knowledge by creating a public health poster.

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:
"Domesticated edible insects are a sustainable protein source that has been gaining global attention. P. brevitarsis is one such species, and their larvae can also eat decaying organic waste and turn it into a plant-growth promoting mixture. But organic matter like this is high in lignocellulose, which is difficult to digest. In fact, these larvae lack the enzymes needed to break lignocellulose down on their own. So, researchers checked their microbiome for microbial genes able to fill in the gaps. The researchers established a comprehensive reference catalog of gut microbial and host genes. Between the two sets of genes, lignocellulose-degrading enzymes were abundant and highly diversified. P. brevitarsis larvae also selectively enriched their microbiome for lignocellulose-degrading microbes and had physiological adaptations that assisted in lignocellulose degradation..."
The rest of the transcript, along with a link to the research itself, is available on the resource itself.

This is a diagram visually summarizing the main stages of food processing: ingestion, digestion, absorption, and elimination. This diagram was created to accompany a chapter on digestion and nutrition modified from the OpenStax Anatomy and Physiology textbook for a nonmajor's biology course.
It was modified for biology instruction by Tina B. Jones from a public domain drawing posted to Wikimedia Commons by Tom Kelly, U.S. Fish and Wildlife Service.
