Anatomy and Physiology are twin disciplines that study the structure and function of the human body, revealing the complexity and interconnectedness of its systems. The video introduces key concepts such as the complementarity of structure and function, hierarchy of organization, and the importance of homeostasis in maintaining internal balance for survival.

Explore the complexity of the human body, from the length of your intestines to the production of saliva and shedding of skin cells. Delve into the intertwined disciplines of anatomy and physiology to understand the structure, function, and interconnectedness of the systems that keep you alive.

The chapter delves into the historical evolution of human anatomy study, from the taboo of dissecting human bodies to the acceptance of certified anatomists performing regulated dissections in public events, leading to the modern practice of using educational cadavers for hands-on learning.

The chapter discusses the fundamental concept of how the structure of cells, tissues, organs, and organ systems in the body is intricately linked to their respective functions. It emphasizes the importance of maintaining homeostasis for survival by balancing internal conditions despite external changes.

The chapter explains the anatomical directional terms and body planes used in anatomy to describe the position of body parts in relation to each other. It covers terms like anterior, posterior, superior, inferior, medial, lateral, proximal, and distal, providing a detailed understanding of how these terms are applied in medical contexts.
