Systems of the Human Body
Daniel D. Chiras holds a Ph. He is also an avid musician, organic gardener, river runner, and bicyclist. Human Body Systems: Structure, Function and Environment focuses primarily on the organ systems that comprise and control our bodies and is written for those who want to learn more about the body's physiological systems, how they operate, and what happens when things go wrong. Written by Dr. Daniel Chiras, author of the best-selling college textbook Human Biology: Health, Homeostasis, and the Environment, Fourth Edition, this book provides the very basics of human anatomy and physiology, offering selected information that should be most useful to the reader without a science background.
Different organs can work together to perform a common function, like how the parts of your digestive system break down food. We refer to an integrated unit as an organ system. Groups of organ systems work together to make complete, functional organisms, like us! There are 11 major organ systems in the human body. The circulatory system is a body-wide network of blood, blood vessels, and lymph.

Book Description: Human Anatomy and Physiology is designed for the two-semester anatomy and physiology course taken by life science and allied health students. The textbook follows the scope and sequence of most Human Anatomy and Physiology courses, and its coverage and organization were informed by hundreds of instructors who teach the course. About this Book Preface I. Chapter 1. An Introduction to the Human Body. Introduction 2.
The digestive system is made up of organs that break down food into protein, vitamins, minerals, carbohydrates, and fats, which the body needs for energy, growth, and repair. After food is chewed and swallowed, it goes down the esophagus and enters the stomach, where it is further broken down by powerful stomach acids. From the stomach the food travels into the small intestine. This is where your food is broken down into nutrients that can enter the bloodstream through tiny hair-like projections. The excess food that the body doesn't need or can't digest is turned into waste and is eliminated from the body. The endocrine system is made up of a group of glands that produce the body's long-distance messengers, or hormones. Hormones are chemicals that control body functions, such as metabolism, growth, and sexual development.
