Complex systems of tissues and organs sense the internal and external environments of multicellular organisms, and through integrated functioning, maintain a stable internal environment within an ever-changing external environment.
As a result of the integration of a number of highly specialized organ systems, complex living things are able to maintain homeostasis while adapting to a constantly changing environment and participating in growth and reproduction. The interactions of these organ systems involves complex regulatory mechanisms that help maintain a dynamic and healthy equilibrium, regardless of their current state and environment.
With these building blocks, medical students will be able to learn how the body responds to internal and external stimuli to support homeostasis and the ability to reproduce.
Category 3A: Structure and functions of the nervous and endocrine systems and ways in which these systems coordinate the organ systems focuses on the structure and functions of the nervous and endocrine systems, and the ways in which the systems work together to coordinate the responses of other body systems...
Category 3B: Structure and integrative functions of the main organ systems focuses on the structure and functions of the organ systems ― circulatory, respiratory, digestive, immune, lymphatic, muscular, skeletal, and reproductive ― and the ways these...
