BSC2085 - Anatomy and Physiology Exam 1 (ch. 1-4)
UPDATED ACTUAL Questions and CORRECT Answers
anatomy the study of the structure and the shape of the body
gross anatomy large structures, easily observable
, microscopic anatomy deals with structures too small to be seen with the naked eye
physiology the study of how the body and its parts work/function
organization level atoms form cells; cells form tissue; tissue form organs; organs form organ
systems; organ systems form organisms
What is the main function of the respiratory system? supply the body with oxygen and remove carbon dioxide
Responsiveness the ability to sense changes (stimuli) in the environment and react to them
survival needs nutrients, oxygen, water, normal body temperature, appropriate atmospheric
pressure
homeostatic controls stimulus, receptor, input, control center, output, response
Stimulus a signal to which an organism responds
Receptor sensor that monitors and responds to changes in environment. sends information
(input) to control center
control center determines how the variable is to be maintained, analyzes information received
and determines appropriate response
effector responds to the stimulus according to control centers variable assessment
(output)
Negative feedback the response to stimuli is to shut off or reduce original stimulus.
Ex: heart rate regulation
positive feedback the response is to increase the original stimulus and push variable further from its
original value.
Ex: giving birth
body cavities
superior (cephalic) toward the head
Inferior (caudal) away from the head end or toward the lower part of a structure or the body;
