Human Organism Flashcards
(45 cards)
It is Study of the structures of the body
Anatomy
It is the study of the body by
organ system
Systemic Anatomy
It is study of the body by areas
Regional Anatomy
study of external features;
superficial structures to locate deeper structures
Surface Anatomy
for examining deepstructures; x-ray, CT scan, PET scan, MRI
Anatomical Imaging – non-invasive method
- Study of the processes and functions of the body
- Main goals; to understand and predict; to understand how the body maintains conditions
Physiology
How atoms interact and combine into molecules
Chemical Level
basic structural and functional unit of organisms
Cell
These are groups of similar cells.
Tissue
group of organs classified as a unit with a common set of functions
Organ System
any living thing considered as a whole
Organism
interrelationship among the
parts of an organism and how those parts interact to perform specific functions
Organization
ability to use energy to perform vital functions
Metabolism
ability to sense changes in the environment and make the adjustments
Responsiveness
Increase in size
Growth
changes an organism undergoes through time
Development
formation of new cells/organisms
Reproduction
- Ability to maintain relatively stable internal conditions
- Balance / Equilibrium
Homeostasis
What does Homeo and Stasis mean?
Homeo - same
Stasis - standing still
normally maintain body temp near an ideal normal value; sweating, shivering
Homeostatic mechanisms
conditions that can change
Variables
ideal value
Set point
acceptable range of values on which HM can still be met
Normal Range
Regulates most systems of the body to maintain
homeostasis
Negative-feedback Mechanism
