Gross
studied area by area.
Regional
studied system by system.
Systemic

Cytology
Study of tissues
Histology
similar to a CT scan but uses a radiopaque dye to enhance differences in areas.
Digital Subtraction Angiography (DSA)
similar to a CT scan but uses a radiopaque dye to enhance differences in areas.
Digital Subtraction Angiography (DSA)
is one step beyond CT scanning. A radiopaque dye is injected into the blood, which allows for enhanced differences when compared to a noninjected scan.
Digital Subtraction Angiography (DSA)
electromagnetic radiation moves through body and is exposed on photographic plate; creates radiograph.
X-ray
This extremely shortwave electromagnetic radiation moves through the body, exposing a photographic plate to form a radiograph
X-ray
create flat, two-dimensional (2D) image.
Radiographs
computer-analyzed x-ray images.
Computed Tomography (CT)
are computer-analyzed x-ray images (a). Some computers are able to take several scans short distances apart and stack the slices to produce a 3D image of a body part

is regulated by feedback loops that allow for a process to be adjusted by the outcome.
Homeostasis
two types of feedbacks loops
negative feedback and positive feedback.
monitors the value of some variable by detecting a stimulus (a change in the variable)
Receptor
establishes the set point and receives input from the receptor.
Control Center
generates the response which can change the value of the variable.

4 Characteristics of life
- Organization
• Metabolism
• Responsiveness
• Growth
condition in which there are specific interrelationships and functions among the parts of an organism
Organization
condition in which there are specific interrelationships and functions among the parts of an organism
Organization

Negative Feedback
Counteracts a change in a variable (for example, body temperature) by decreasing the change to help maintain homeostasis by returning to the set point.
Negative feedback
Counteracts a change in a variable (for example, body temperature) by decreasing the change to help maintain homeostasis by returning to the set point.
