Answers
• Complementarity of Structure and Function -✓✓function depends on anatomy
• Level of structural organization -✓✓chemical, cellular, tissue, organ, organ
system, organismal
• Chemical -✓✓includes atoms and molecules
• Cellular -✓✓includes organelles (smallest units of living things)
• Tissue -✓✓four major types are epithelial, connective, muscle and nervous.
• Organ -✓✓contains two or more types of tissue that perform a common function
• Organ System -✓✓contains several organs that work together to perform a
common function.
• Organismal -✓✓most complex organizational level and sum of all structural
levels working together
• Necessary Life Functions -✓✓1. Maintaining boundaries
2. Movement
3. Responsiveness
4. Digestion
5. Metabolism
6. Excretion
7. Reproduction
8. Growth
• Maintaining boundaries -✓✓separates the internal environment from the external
environment; cell membrane or skin
• Movement -✓✓activities promoted by the muscular system
, • Responsiveness (irritability) -✓✓the ability to sense changes in the environment
and then to react to them
• Digestion -✓✓breakdown of ingested foodstuffs to simple molecules so that they
can be absorbed into the blood
• Metabolism -✓✓sum of all chemical reactions that occur within the body: §
Anabolism - synthesizing more complex cellular structures from simpler
substances § Catabolism - breaking down substances into simpler building blocks
• Excretion -✓✓the process by which wastes are removed from the body
• Reproduction -✓✓occurs on both the cellular and organismal level
• Growth -✓✓increase in size due to an increase in the number of cells
• Survival needs -✓✓nutrients - used for energy and cell building, oxygen - needed
to break down nutrients, water - single most abundant chemical substance in the
body, normal body temperature - needed in order to maintain the correct speed of
metabolic reactions, and appropriate atmospheric pressure - necessary for proper
breathing and gas exchange
• Integumentary -✓✓contain the skin to form the external body covering, protect
deeper tissues from injury, synthesizes vitamin D and houses cutaneous receptors
and sweat and oil glands
• Skeletal -✓✓protects and supports body organs, provides framework the muscles
use to cause movement, blood cells are formed within bones (process of
hematopoiesis), bones store minerals
• Muscular -✓✓manipulation of the environment, locomotion, and facial
expression; maintains posture and produces heat
• Nervous -✓✓releases nerve impulses that control muscles, glands, etc. • Contains
brain, spinal cord and peripheral nerves
