Cells do not exist in isolation. They communicate via chemical and electrical signals to coordinate activities. Signal transduction pathways allow extracellular signals (first messengers) to induce intracellular changes, often involving second messengers like cyclic AMP (cAMP) or Calcium ions (Ca2+). This cellular communication is the prerequisite for the coordination of tissues and organs.
Focuses heavily on the mechanism of homeostasis. Conclusion

A textbook's credibility is often tied to its author. Lauralee Sherwood brings a wealth of expertise to this work. After graduating from Michigan State University in 1966, she joined the faculty at West Virginia University, where she is now a Professor in the Department of Physiology and Pharmacology, School of Medicine. For over 40 years, she has taught courses for a wide range of health profession students, including pharmacy, nursing, medicine, and exercise physiology. Beyond this textbook, she has also authored Fundamentals of Human Physiology and Animal Physiology: From Genes to Organisms , all published by Cengage Learning. Her numerous teaching awards are a testament to her ability to make complex concepts clear and engaging, a quality that shines through on every page of her writing.

Over her extensive career, she has taught over 400 students annually across various majors, including pharmacy, nursing, medical, dental, and exercise physiology. This direct teaching experience allowed her to refine her approach, resulting in a textbook that truly understands the challenges students face. She has authored three physiology textbooks, with Human Physiology: From Cells to Systems being her flagship work.
Sherwood's pedagogical approach is built on several key features that distinguish her book from others:
Explains innate versus adaptive immunity, antibody production, and how the body fights off pathogens.
