Module 1 Flashcards
Intro and Homeostasis
Matching wings to flight would be an example of
Structure-Function Complementarity
Studying the structure of cells and their location would be an example of what
Microscopic Anatomy
What is not an example of a life function
height and weight
Maintaining homeostasis is done by a process of Negative Feedback which includes…
Sensing, Effectors, and Integration
Homeostasis
Balancing essential variables for life and health
Set Point
Blood Glucose= 70-120 mg/dL
Negative Feedback
System to correct homeostasis disturbances
Shivering
example of an effector
T/F In giving birth, the process of increasingly intense labor contractions would be an example of Negative Feedback
False
T/F Measuring our hearth rate after climbing stairs examined the Effectors of Negative Feedback
True
Name the 5 essential variables for sustaining life on Mars
H2O, O2, Food, Moderate Temperatures, Atmospheric pressure
what is anatomy
the study of the structure of body parts and their relationship to one another
what type of questions does anatomy ask
“What is it?”
what is physiology
the study of the function of the body’s structural machinery
what type of questions does physiology ask
“How does it work? Why did it do that?”
what is the theme of homeostasis
“the wisdom of the body”
what is meant by internal environment
70% H2O
what are examples of variables of internal envirnoment
H20 volume (blood pressure), temperature, pH, other electrolytes, O2/COs, glucose and other furls
what is the mechanism of maintaining homeostasis
sensing, integration, effectors
what is positive feedback
positive pushes the variable further away from the set point
what are the consequences of positive feedback
homeostasis disturbance and death
what are good examples of positive feedback
parturition and child labor
what is pathophysiology
the study of disease
