See how dietary fat from food we eat travels through the digestive system, and gets packaged and stored in the human body. [2:07]
Biology 2e is designed to cover the scope and sequence requirements of a typical two-semester biology course for science majors. The text provides comprehensive coverage of foundational research and core biology concepts through an evolutionary lens. Biology includes rich features that engage students in scientific inquiry, highlight careers in the biological sciences, and offer everyday applications. The book also includes various types of practice and homework questions that help students understand—and apply—key concepts. The 2nd edition has been revised to incorporate clearer, more current, and more dynamic explanations, while maintaining the same organization as the first edition. Art and illustrations have been substantially improved, and the textbook features additional assessments and related resources.
By the end of this section, you will be able to do the following:
Describe the process of digestion
Detail the steps involved in digestion and absorption
Define elimination
Explain the role of both the small and large intestines in absorption
By the end of this section, you will be able to do the following:
Discuss the role of neural regulation in digestive processes
Explain how hormones regulate digestion
By the end of this section, you will be able to do the following:
Explain the processes of digestion and absorption
Compare and contrast different types of digestive systems
Explain the specialized functions of the organs involved in processing food in the body
Describe the ways in which organs work together to digest food and absorb nutrients
By the end of this section, you will be able to do the following:
Explain why an animal’s diet should be balanced and meet the needs of the body
Define the primary components of food
Describe the essential nutrients required for cellular function that cannot be synthesized by the animal body
Explain how energy is produced through diet and digestion
Describe how excess carbohydrates and energy are stored in the body
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.
This comprehensive study guide covers the main terms and concepts needed for a unit on the digestive system.
A free CK-12 account is required to view all materials.
Paul Andersen starts with a brief description of feeding methods. He then details all of the major parts within the human digestive system. This tour starts in the mouth, move down the esophagus, through the stomach, small intestine, colon, and rectum. He explains how all of the major macromolecules are digested and absorbed by the body. A review worksheet is provided as well. [9:38]
Page focuses on the processes involved in the generation of monosaccharides and their absorption into the digestive tract. Image shows the transport of glucose across the intestinal epithelium.
Describes the human stomach in terms of its structural components.
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.
The digestive system is investigated in this learning activity to help participants learn how food is broken down and prepared for absorption, and list the components of the digestive system as well as their functions. Organs investigated include the mouth, esophagus, stomach, small intestine, large intestine, rectum, and anus.
A narrated lesson exploring the causes and affects of various disorders of the digestive system. [7:15]
The Digestion and Nutrition Student Edition book is one of ten volumes making up the Human Biology curriculum, an interdisciplinary and inquiry-based approach to the study of life science.
