1. Anatomy The branch of biology that attempts to understand how things are structured
internally and externally
2. Physiology The branch of Biology that attempts to understand how things work
3. Levels of physio- body
logical study system
orans
tissues
cells
organelles
ion channels
4. Homeostasis Maintaining the internal state within narrow limits even during external change
5. How is home- Autoregulation or extrinsic regulation
ostasis main-
tained?
6. Autoregulation occurs when the activity of a cell/tissue/organ adjusts automatically in response to
environmental change
7. Extrinsic regula- changes result from the actions of the nervous or endocrine system
tion
8. General regula- Receptor, control center, and effector
tory mechanisms
consist of:
9. Negative feed- Response shuts off or migrates to original stimulus
back
10. Positive feedback Response exaggerates original stimulus

11. Metabolism sum of all chemical reactions in cells (catabolic + anabolic reactions)
12. Catabolic reac- "decomposition" - snipping large into small
tions
13. Anabolic Reac- "synthesis"- building small into large
tions
14. Inorganic Com- Molecules that do not contain carbon chains
pounds
15. Hydrophilic attracted to water
16. Hydrophobic Repels water
17. How does water Cells remain liquid over a wide temp range and maintains homeostasis
have a high heat
capacity?
18. Acids Release H+ ions when dissociates
19. Bases Removes H+ ions from solution
20. Buffers resists changes in pH
21. Lipids -Do not dissolved readily in water
-non-polar
22. Proteins - contain C,H,O,N, and S
- composed of 20 basic types of amino acids bound together with peptide bonds
23. Primary Struc- determined by the number, kind, and arrangement of amino acids
ture of a protein
