Anatomy & Physiology |
Human structure and function, biology of human body, FORM SUPPORTS FUNCTION |
|
|
|
Gross anatomy |
Visible structures |
Dissection |
|
|
Comparative anatomy |
Study of more various species, examine similarities and differences, evolutionary trends |
|
|
|
Microscopic anatomy |
HISTOLOGY, not visible structures, tissues of body |
|
|
|
Physiology can vary |
Ex: sex, age, weight, diet |
|
|
|
Defined normal range |
Range of variability where normal function occurs |
Weight, heart rate |
|
|
What is essential for life? |
1. Organization 2. Cellular composition 3. Development 4. Reproduction 5. Metabolism 6. Homeostasis |
|
|
|
Organization |
Living things have higher level of organization than nonliving, great energy |
|
|
|
Cellular composition |
Living matter is always compartmentalized into one or more cells |
|
|
|
Development |
Organism changes overtime, differentiation or growth |
|
|
|
Reproduction |
Pass genes to offspring, produce copies |
|
|
|
Metablosim |
Sum of all internal chemical change, fast or slow you process something |
|
|
|
Homeostasis |
Regulating the body, stable internal conditions, not absolutely constant(fluctuate), maintain around set point |
|
|
|
The body's structural hierarchy |
Organism Organ system Organ Tissue Cells Organelles Macromolecules Molecule Atom |
|
|
|
Organism |
Single complete individual |
|
|
|
Organ system |
Group of organs, unique collective function |
|
|
|
Organ |
Structure composed of tissue(s), work to carry out certain function |
|
|
|
Tissue |
Mass of similar cells, histology |
|
|
|
Cells |
Smallest units of an organism, basic functions of life |
|
|
|
Cytology |
Study of single cells and organelles |
|
|
|
Organelles |
Microscopic cellular structures, individual functions |
|
|
|
Molecules |
Make up organelles and other cellular components, have at least 2 atoms |
|
|
|
Macromolecules |
Protiens, carbohydrates, fats, DNA |
|
|
|
Atoms |
Smallest particles, unique chemical identities |
|
|
|
Negative feedback loop |
⬆⬇reverse the direction of initial response, opposite direction, most common |
|
|
|
Positive feedback loop |
⬆⬆ Try to reinforce, work together, enhance initial response, rare |
|
|
|
Vasodilation |
Blood vessels expands closer to skin, sweating |
|
|
|
Vasoconstriction |
Blood vessels smaller, closer to internal organs, shivering |
|
|
|
What affects negative feedback? Ex:body temp |
Vasodilation and Vasoconstriction |
|
|
|
What contains thermostat to sense change? |
Brain |
|
|
|
Scientific method |
How we understand info we know, look at everything to make conclusions |
|
|
|
Inductive method |
Make numerous observation to draw conclusions |
|
|
|
Where is knowledge of anatomy obtained? |
By inductive method |
|
|
|
Most of physiological knowledge is gained from? |
Hypothetico-deductive method |
|
|
|
Research |
Tests hypothesis, see if yes or no, then reform |
|
|
|
Theories are developed by... |
Confirmed hypothesis, along with known scientific facts and laws |
|
|
|
Scientific fact |
Info seen multiple times, verified by trained person |
|
|
|
Law |
Generalization about the predictable way of matter and energy behave, results from inductive reasoning |
|
|
|
Theory |
Explanation to how something works, what we do and don't know |
|
|
|
Hypothetico- deductive method |
Formation of hypothesis and experimentation to support or go against an idea |
|
