Introduction Flashcards
Anatomy means…
to cut or to dissect: the structure of the body
Physiology
the function of the body and how our body works
6 level of Organism
Chemical, Cellular, Tissue, Organs, Organ system, Organisms
what sustains the physical and chemical changes in organism ability to acquire and make use of the energy for changes
Metabolism
to sense internal and external environmental changes
Responsiveness
increase in size :cell, group of cells, extracellular materials
Growth
increase in size and form: cell structure, fuction and form. generalized -> specialized
Development
formation of new cells and organisms
Regeneration
Functional interrelationship between parts
Organization
Homeostasis means
comes from greek word: “homois” similar or same “stasis” standing
-steady balance environment or state
measures the change in value
Variables
normal extent of increase and decrease in a set point
Normal Range
Normal value or average of variable
Set point
T or F - “overtime body temperature stay still around the set point”
F- body temperature fluctuates around set point
components of feedback
receptor, control center, effector
2 feedbacks in Homeostasis
Negative Feedback and Positive Feedback
Main Mechanism and most used in Homeostatic Regulation
Negative Feedback
2 parts of NF
Detection- detect the deviation away from set point
Correction- bring back, toward set point or normal range
initial stimulus further stimulates the response: progressive deviation
Positive Feedback
occurs under normal conditions like: giving birth and hemostasis
Positive Feedback
often times harmful, but there are few beneficial
Positive Feedback
Normal body Temperature
37 C
T or F- set points in some variables is permanently adjusted depending on body activities
F- its is only temporary not permanently
Regulation of homeostasis can be accomplished in what system?
Endocrine and Nervous System - both have a receptor and effector
