The human body is a living machine. Like a machine, it has intricate parts, known as organ systems, which work together to accomplish certain tasks: circulation, respiration, digestion, nerve impulses, and immune responses. In this module, you will explore the circulatory, respiratory, digestive, excretory, nervous, and immune systems. You will also learn how these systems work together to maintain homeostasis. Through this module, you will gain a better understanding of how the human body functions every moment of every day.
