Tema 1 (17 cards)
Scientifc study study of the body’s structure
anatomy
____ anatomy studies large structures while __________ anatomy studies small ones
gross
microscopic
Scientific study of the chemistry and physics of the structure of the body and the ways in which they work together to support life function
Physiology
study of the brain, spinal cord, and nerves and how these work together to perform fucntions as complex and diverse as vision, movement and thinking
Neurophysiology
State of steady internal conditions mainatined by living things
Homeostasis
Physiological value around which the normal range fluctuates like 37*C
Set point
Restricted set of values that is optimally healthy and stable
Normal Range
Mechanism that reverses a deviation from the set point; like sweating when it is hot
Negative Feedback
Intensiefies a change in the body’s physiological condition rather than reversing it only when there is definite point; like giving birth
Postive feedback
the ______ __________ of the human body increases in complexityand the basic architecture on how parts are assembled
structural organization
Simplests blocks of matter like subatomic particles, atoms, molecules.

tissue
