Respiratory physiology ✔️functioning of respiratory organs
Reproductive physiology ✔️the functioning of the hormones and reproductive cycle
Homeostasis ✔️the body's ability to maintain a stable internal environment
Receptor ✔️component of homeostasis that the structure that detects changes in the stimulus, sensory
nerves
Stimulus ✔️component of homeostasis that changes in a variable that is regulated
, Control center ✔️component of homeostasis that processes the change that occurred from the
receptor
Negative feedback ✔️if it is high, lower it. If it is low, raise it. Negative because the response is opposite
of the stimulus
Set point ✔️variable maintained within a normal level
The hypothalamus ✔️part of the brain that regulates body temperature
Positive feedback ✔️moves the stimulus in the same direction, occurs less frequently than negative
feedback
Simplest levels of organization composed of chemical structures ✔️atoms, ions, and molecules
Human body is composed of matter ✔️solid, liquid, gas that is anything that has mass or takes up space
Matter is composed of ✔️atoms
