anatomy - Correct Answers the structure of body parts and their relationship to one another
physiology - Correct Answers the study of how the body and its parts work or function
Gross or macroscopic anatomy - Correct Answers study of large body structures visible to the naked eye
Gross anatomy - Correct Answers regional, systemic, surface
Microscopic anatomy - Correct Answers deals with structures too small to be seen with the naked eye
subdivisions = cytology (cells), and histology (tissues)
Human structural organization - Correct Answers Chemical level (atoms combine to form molecules)
Cellular level (cells are made up of molecules)
Tissue level (tissues consist of similar types of cells)
Organ level (organs are made up of different types of tissues)
Organ system level (organ systems consist of different organs that work together closely)
organismal level (the human organism is made up of many organ systems)
digestive system - Correct Answers takes in nutrients, breaks them down, and eliminates unabsorbed
matter (feces)
,cardiovascular system - Correct Answers The transport system of the body responsible for carrying
oxygen and nutrients to the body and carrying away carbon dioxide and other wastes; composed of the
heart, blood vessels, and blood.
respiratory system - Correct Answers Brings oxygen into the body. Gets rid of carbon dioxide.
urinary system - Correct Answers Eliminates nitrogenous wastes from the body. Regulates water,
electrolyte and acid-base balance of the blood.
integumentary system - Correct Answers Protects the body from invaders by providing a tough
protective layer. Warms the body. Cools the body.
Responsiveness - Correct Answers Reaction to a change inside or outside the body
metabolism - Correct Answers All of the chemical reactions that occur within an organism
catabolism - breaking down
anabolism - create new
create ATP
depends on the digestive and respiratory systems to make nutrients and oxygen available to the blood,
and on the cardiovascular system to distribute them throughout the body
exrection - Correct Answers Is the removal of waste products of METABOLISM.
Reproduction - Correct Answers the process of producing offspring
survival needs - Correct Answers nutrients, oxygen, water, normal body temperature, appropriate
atmospheric pressure
homeostasis - Correct Answers maintenance of a stable internal environment
, -maintained by negative feedback
Receptor - Correct Answers first component to maintaining homeostasis.
-sensor that monitors the environment
-responds to stimuli (changes) by sending info (input) alone the afferent pathway to the second
component, the control center
control center - Correct Answers determines the set point at which the variable is maintained
-analyzes input it receives by comparing it to the set point. information (output) flows from the control
center along the efferent pathway to the third component, the effector
effector - Correct Answers carries out the final corrective action to restore homeostasis
-results of the response feed back to influence the effect of the stimulus
negative feedback mechanisms - Correct Answers feedback that causes the stimulus to decline or end
-output shuts off original effect of the stimulus or reduces its intensity
-return to "ideal" value
positive feedback mechanisms - Correct Answers Feedback that tends to cause the level of a variable to
change in the same direction as an initial change
-change that results in the same direction as the intial chance, causing the variable to deviate further
from its original value or range
-usually control infrequent events that do not require continuous adjustments
-blood clotting is an example
homeostatic imbalance - Correct Answers a disturbance in homeostasis resulting in disease
