Human Physiology- Chapter 1
1. human physiology: the study of how living organisms function
2. What are the major themes of physiology?: 1. Structure and
function are closely related
2. Living organisms need energy- energy source, transfer, storage, and
use
3. Information flow coordinates body function
4. Homeostasis maintains internal stability despite external variables
3. How is the body organized?: - chemical (molecular) level
- cellular level
- tissue level
4.On what level are carbon dioxide, water, and macromolecules found?:
chem- ical level (molecular level)
5.What level of organization contains cells and their functional subunits
(a.k.a. organelles)?: cellular level
6. What level of organization contains a group of cells working together
to perform a common function?: tissue level
7. What are the four types of tissue and their main function?: Epithelium-
covers body's surfaces
Connective- provides

, Human Physiology- Chapter 1
support Muscle-
movement
Nervous - communication
8. organ level: a discrete structure made up of more than one tissue;
functional center
9. organ system: organs working closely together for a common purpose
10.organism level: highest level of organization; the result of all
simpler levels working in unison
11.tissues (informal definition): work together in functionally related
communities
12.tissues (formal definition): a group of closely associated cells that
perform related functions and are similar in structure
13.Are tissues composed only of living cells?: No, there is a non-living
extracel- lular component, which is the extracellular matrix
14.Characteristics of epithelium tissue:: - a sheet of cells
- covers a body surface or lines a body cavity
- forms most of the body's glands
- occurs at interfaces between differing environments (inside vs. outside
the body)
