Transcript of A/P - Intro to Anatomy/Physiology

Introduction to Anatomy and Physiology
The study of the structures of the body
What is Anatomy?
What is Physiology?
The study of the functions of the body
Typically involves using dissection or imaging techniques
Typically involves using experimentation and measuring (numbers)
Levels of Structural Organization
any form of life
a group of related organs with a common function
Organ System
structures made of two or more types of tissues that perform a certain function
groups of cells that work together to perform a function
basic units of structure and function of an organism
All chemicals are made of atoms
Molecules are made of two or more atoms joined together
Basic Life Processes
ability to detect and respond to change
allows movement of body and structures within the body
sum of all chemical reactions that occur in the body
increase in size
development of a cell from an unspecialized to a specialized state
Production of a new individual
Maintaining of balance in the body
Makes new structures, stores energy, releases energy
More cells created than are being destroyed
Cells getting larger
Increase in material between cells
Maintaining volume and makeup of body fluids
Maintaining pH balance
Maintaining body temperature
Anatomical Terminology
Body Positions
Regional Names
Directional Terms
Planes and Sections
Body Cavities
Abdominopelvic Regions and Quadrants
Standing upright, facing the observer, head level, eyes facing forward, arms at sides with hands pointing forward, feet flat on the floor and directed forward
Anatomical Position
Body is lying face up
Body is lying face down
Major Organ Systems
Protects and supports the body
covers and protects the body
Allows movement
breaks down food, absorbs nutrients, eliminates wastes
eliminates wastes, maintains balance of chemicals in the body
regulates, interprets, and responds
regulates body activities through hormones
Transfers gasses between the environment and the blood.
Pumps and transports blood
returns proteins and fluids to blood, involved in fighting disease

1. Dorsal body cavity includes the cranial cavity and the spinal cavity. It is surrounded by bone.
2. Ventral body cavity contains all of the organs in the abdomen and the chest.
3. Thoracic cavity is above the diaphragm and is separated from the lower parts by the diaphragm.
4. Abdomenopelvic cavity contains all the organs from the diaphragm to the rectum.
5. Abdominal cavity contains organs such as the stomach, liver, and intestines.
6. Pelvic cavity contains the reproductive organs, bladder, and rectum.
