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 chapter, you will be able to:Describe the roles of male and female reproductive hormonesDiscuss the interplay of the ovarian and menstrual cyclesDescribe the process of menopause

The Your Changing Body 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.

This course is designed to give the student a clear understanding of the pathophysiology of the menstrual cycle, fertilization, implantation, ovum growth development, differentiation and associated abnormalities. Disorders of fetal development including the principles of teratology and the mechanism of normal and abnormal parturition will be covered as well as the pathophysiology of the breast and disorders of lactation. Fetal asphyxia and its consequences will be reviewed with emphasis on the technology currently available for its detection. In addition the conclusion of the reproductive cycle, menopause, and the use of hormonal replacement will be covered.

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:

"New research finds that female mice are most vulnerable to air pollution early in their reproductive cycle That finding calls for a closer look at menstrual cycle phase when studying air pollution effects in women Researchers gathered mice at two different stages of their reproductive cycle marked by clear differences in circulating sex hormones They then exposed each group to ozone, a reactive air pollutant known to worsen symptoms of lung disease Those in the earlier phase showed higher activation of the immune system, suggesting higher sensitivity to air pollution at that time The carryover to women hasn’t yet been explored But the overall message is clear Women’s hormonal status should always be recorded in studies on air pollution and lung inflammation Fuentes et al. "Modulation of the lung inflammatory response to ozone by the estrous cycle..."
