Anatomy & Physiology Chapter 1-2 Study
Guide with Answers Graded A+
What is the difference between Anatomy & Physiology? - Answer Anatomy is the study of the
STRUCTURE of the human body and its parts. Physiology is the study of how parts of the body work and
carry out their FUNCTIONS.
What are the 3 main topics in the study of Anatomy and physiology? - Answer 1. Complimentary of
structure and function
2. Hierarchy of structural organization
3. Homeostasis
what does ¨complimentary of structure and function¨ mean? - Answer It is how an organ or system
functions that depends on its structure
What is the hierarchy of structural organization in humans? - Answer chemical - all things are made up
of atoms and molecules
cellular- cells are the smallest units of life
tissue- groups of similar cells that have a common function
organ- structures composed of two or more tissues that perform a specific function
organ system- organs work together for a common purpose
organismal- all organ systems working together to enable a living thing to carry out all of life´s functions.
What are the life functions and survival needs in humans? - Answer LIFE FUNCTIONS
~ Maintain boundaries
, ~Movement
~Responsiveness
~Digestion
~Metabolism
~Excretion
~Reproduction
~Growth
SURVIVAL NEEDS
~Nutrients
~Water
~Oxygen
~Normal body temperature
~Appropriate Atmospheric pressure
What is homeostasis? - Answer It is the body´s ability to maintain relatively stable internal conditions
( State of balance). It is controlled by the nerve and endocrine systems through a process of feedback.
Homeostasis is so important that most disease can be described as a result of a homeostatic imbalance.
How does positive and negative feedback work? - Answer Negative feedback (Bad):
~brings the factor or variable back to balance.
~works like a thermostat
ex; heart rate & blood glucose levels
Positive feedback:
~causes the factor or variable to proceed at an increasing rate.
~ snowball effect
ex; blood clotting & labor of child birth
