Category 3B within foundational concept 3 is the final portion in the Biological and Biochemical Foundations of Living Systems section of the MCAT exam. Category 3B specifically focuses on the structure and functions of various organ systems, including reproductive, circulatory, respiratory, immune, digestive, lymphatic, muscular and skeletal. Category 3B also looks at the ways all of these systems work in concert to perform their roles in the maintenance and continuance of living organisms.
Overview of Foundational Concept 3, Category 3B
The body uses several complex, organized and integrated organ systems to perform the functions required to maintain life processes. No organ system within the human body is on an island to itself, and it is the complex coordination and interactions between the respective systems that allows organisms to engage in the processes that are necessary to sustain life. This is information you can expect to be quizzed about on this portion of the exam.
