Human Physiology- Chapter 1exam
with correct answers graded A+
human physiology - correct answer-the study of how living organisms function
What are the major themes of physiology? - correct answer-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
How is the body organized? - correct answer-- chemical (molecular) level
- cellular level
- tissue level
On what level are carbon dioxide, water, and macromolecules found? - correct answer-chemical level
(molecular level)
What level of organization contains cells and their functional subunits (a.k.a. organelles)? - correct
answer-cellular level
What level of organization contains a group of cells working together to perform a common function? -
correct answer-tissue level
What are the four types of tissue and their main function? - correct answer-Epithelium- covers body's
surfaces
Connective- provides support
Muscle- movement
Nervous - communication
, organ level - correct answer-a discrete structure made up of more than one tissue; functional center
organ system - correct answer-organs working closely together for a common purpose
organism level - correct answer-highest level of organization; the result of all simpler levels working in
unison
tissues (informal definition) - correct answer-work together in functionally related communities
tissues (formal definition) - correct answer-a group of closely associated cells that perform related
functions and are similar in structure
Are tissues composed only of living cells? - correct answer-No, there is a non-living extracellular
component, which is the extracellular matrix
Characteristics of epithelium tissue: - correct answer-- 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)
Functions of Epithelium tissue: - correct answer-Protection
Secretion
Absorption
Ion transport
Filtration
Forms slippery surfaces
What is the most diverse and abundant type of tissue? - correct answer-connective tissue
What are the four main classes of connective tissue? - correct answer-Connective tissue proper
