In this unit, students learn about the form and function of the human heart through lecture, research and dissection. Following the steps of the Legacy Cycle, students brainstorm, research, design and present viable solutions to various heart conditions as presented through a unit challenge. Additionally, students study how heart valves work and investigate how faulty valves can be replaced with new ones through advancements in engineering and technology. This unit demonstrates to students how and why the heart is such a powerful organ in our bodies

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:Describe an open and closed circulatory systemDescribe interstitial fluid and hemolymphCompare and contrast the organization and evolution of the vertebrate circulatory system.

By the end of this section, you will be able to:Identify the spinal cord, cerebral lobes, and other brain areas on a diagram of the brainDescribe the basic functions of the spinal cord, cerebral lobes, and other brain areas

This lesson describes how the circulatory system works, including the heart, blood vessels and blood. Students learn about the chambers and valves of the heart, the difference between veins and arteries, and the different components of blood. This lesson also covers the technology engineers have developed to repair the heart if it is damaged. Students also understand how the circulatory system is affected during spaceflight (e.g., astronauts lose muscle in their heart during space travel).

Students learn about the form and function of the human heart through lecture, research and dissection. They brainstorm ideas that pertain to various heart conditions and organize these ideas into categories that help them research possible solutions. An expert in the field of cardiac valve research was interviewed for this lesson and shares his ideas with the class. Students conclude by researching various possible heart defects.

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:Recognize the essential nature of schizophrenia, avoiding the misconception that it involves a split personalityCategorize and describe the major symptoms of schizophreniaUnderstand the interplay between genetic, biological, and environmental factors that are associated with the development of schizophreniaDiscuss the importance of research examining prodromal symptoms of schizophrenia

This lesson contains background about the blood vascular system and the heart. Also, the different sizes of capillaries, veins, and arteries, and how they affect blood flow through the system. We will then proceed to talk about the heart's function in the blood vascular system. This will lead into a discussion of heart valves, how they work and what might cause them to fail. Then we will discuss prosthetic heart valves.

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:

"Congenital heart defects (CHDs) are common, affecting 9 out of every 1000 babies born. CHDs are caused by various gene mutations that prevent the heart chambers and/or valves from forming properly. However, the precise mechanisms of chamber development and how they are dysregulated in fetuses with CHDs are unclear. To learn more, researchers recently investigated the molecular signals of heart development in a zebrafish animal model. They found that all heart cells expressed the gene sema3fb, which encodes the cell guidance cue Sema3fb. However, only ventricle-specified cells expressed the gene encoding this cue’s receptor, Plxna3, effectively restricting Sema3fb signaling to the ventricle. In zebrafish embryos with sema3fb mutations (ca305 and ca306), heart chamber development was impaired. Specifically, the atrium and ventricle were too small because the cells were shrunken, which caused the heart to pump less blood and fill with fluid..."
