Anatomy and Physiology Overview Flashcards
What is Human Anatomy?
Study of structure and shape of the body
What is gross Anatomy?
Structures you can see
What is microscopic Anatomy?
Structures you can see only with the help of a scientific instrument
What is Physiology?
study of the function of living things
What are the levels of organization?
- Chemical
- Cellular
- Tissue
- Organ
- Organ system
- Organism
Define the Chemical level
simplest, atoms combine to form molecules.
Define the Cellular level
Cells are made of molecules.
Define the tissue level
Tissue consist of similar type of cells
Define the Organ level
Organs are made up of different types of tissues
Define the Organ System level
different organs that work together closely
Define Organismal level
made up of many organ systems
How is Anatomy studied?
organs are dissected to be examined
How is Physiology studied?
through urine or blood tests
List the Characteristics of Life
- Metabolism
- Responsiveness
- Movement
- Growth
- Differentiation
- Reproduction
- Maintaining boundaries
Define Metabolism
sum of all chemical reactions
Define Responsiveness
- ability to sense a change and react
- ability to detect and respond to change
Define Movement
motion
Define Growth
growth in size or number or both
Define Differentiation
unspecialized cells become specialized
Define Reproduction
- formation of new cells
- productions of a new individual
Define Homeostasis
the body’s ability to maintain relatively stable internal conditions
What are the three components of all homeostatic mechanisms?
- Receptor
- Control Center
- Effectors
Define the Receptor
- monitors change and responds with an input
Define the Control Center
- evaluates the input and sends a message
Define the Effectors
- carries out the response
Explain a negative feedback loop
- most common
- eliminates the stimulus that creates the change
Give examples of a negative feedback loop
- heart rate
- blood pressure
- breathing rate
- release of hormones
- blood sugar
- blood levels
Explain a positive feedback loop
strengthens or enhances the change
Give examples of positive feedback loop
- blood clotting
- birth of baby
