BSC 2085 Exam 1 (Chapters 1) UPDATED ACTUAL QUESTIONS AND CORRECT
ANSWERS
Anatomy study of the structure of body parts and their relationships to one another
Physiology function of the body
Examples of anatomy Cytology (study of cells) & Histology (study of tissues)
, Examples of physiology -study of position
-cellular energy requires the body's production of ATP
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
