Intro to Anatomy and Physiology Flashcards
What is anatomy?
The study of the structures within the human body
What is microscopic anatomy?
Studying smaller structures and requires a microscope
What is gross anatomy?
Studying larger structures through dissections
How do you identify structures within organ systems?
Size, Shape, and Location
What is physiology?
The study of the function within the body
What processes are involved within the body?
Chemical, Physical, Electrical
What is the relationship between anatomy and physiology?
Depends upon one another, Structure determines function, and Anatomy must be studied first

What is the tissue level?
Cells similar in structure and function joined together
What are the types of tissues?
Epithelial, muscle. connective, and nervous
What is the organ level?
when groups of different tissues work together and form an organ
What is an organ system?
Groups of organs that perform related functions interact to accomplish a common activity
What is an organism?
All cells, tissues, organs, and organ systems together
