Study Notes

Anatomy and Physiology

Anatomy refers to the study of body structures, derived from Greek terms meaning "to cut apart."
Gross anatomy involves examining observable structures through dissection, while microscopic anatomy focuses on cells and tissues visible only under a microscope.

Physiology

Physiology is the study of body functions and how parts work together, with subdivisions like neurophysiology and cardiac physiology addressing specific systems.

Relationship Between Anatomy and Physiology

Anatomy and physiology are interdependent; the structure of body parts dictates their functions.
Example: Thin walls of lung air sacs allow for gas exchange, while the heart's muscular structure enables it to pump blood.

Concept Links

Concept Links throughout the text emphasize the connections between different concepts and organ systems.
The aim is to understand both individual systems and their interactions for sustaining life.

Levels of Structural Organization

Six levels of structural organization in the human body, progressing from atoms to organisms, describe the complexity of biological structures.
The simplest level is the chemical level where atoms combine to form molecules (e.g., water, proteins).
Molecules form cells, the basic living units of life, which vary in size and function.

Tissues, Organs, and Functions

Tissues are groups of similar cells performing a common function, categorized into four basic types.
An organ is formed from two or more tissue types working together for specific bodily functions.
Example: The small intestine is an organ composed of all four tissue types, involved in digestion and nutrient absorption.
