✔✔What is homeostasis? - ✔✔the ability to maintain a relatively stable internal
environment in an ever-changing outside world
✔✔What are control mechanisms for homeostasis? - ✔✔receptor is a sensor that
monitors the environment and responds to changes, called stimuli and then sends info
to the control center where it is analyzed and determines the appropriate response or
course of action and then to the effector which provides the means for the control
centers output
✔✔What is negative feedback within homeostasis? and example - ✔✔the response
reduces or shuts off the original stimulus regulation of body temp (nervous mechanism)
regulation of blood volume by ADH (endocrine mechanism)
✔✔What separates living beings from nonliving objects? - ✔✔Living organisms are able
to maintain their boundaries, move, respond to environmental change, digest nutrients,
carry out metabolism, dispose of wastes, reproduce and grow. while inanimate objects
do not exhibit all of these
, ✔✔what name is given to all chemical reactions that occur within body cells -
✔✔metabolism
✔✔Why is it necessary to be in a pressurized cabin when flying at 30,000 feet? -
✔✔because the atmosphere is thinner at high altitudes and the amount of oxygen
entering the blood under such conditions may be insufficient to maintain life
✔✔What's the process of negative back for regulation of blood volume by ADH -
✔✔Receptors sense decreased blood volume, control center in hypothalamus
stimulates pituitary gland to release antidiuretic hormone ADH, ADH causes the kidneys
(effectors) to return more water to the blood.
✔✔What is positive feedback examples - ✔✔the response enhances or exaggerates
the original stimulus; exhibits an amplifying effect; usually controls infrequent events ex:
enhancement of labor contractions by oxytocin, platelet plug formation and blood
clotting
✔✔Homeostatic imbalance is the ...what does this cause? - ✔✔disturbance of
homeostasis increases risk of disease, contributes to changes associated with aging,
may allow destructive positive feedback mechanisms to take over (heart failure)
✔✔the head is _______ to the abdomen - ✔✔superior
✔✔the navel is ______ to the chin - ✔✔inferior
✔✔the breastbone is _____ to the spine - ✔✔anterior (ventral)
✔✔the heart is _____ to the breastbone - ✔✔posterior (dorsal)
✔✔the heart is _____ to the arm - ✔✔medial
✔✔the arms are _____ to the chest - ✔✔lateral
✔✔the collarbone is _________ between the breastbone and shoulder -
✔✔intermediate
✔✔the elbow is _______ to the wrist - ✔✔proximal
✔✔the knee is ___ to the thigh - ✔✔distal
✔✔the skin is ________ to the skeletal muscles - ✔✔superficial
✔✔the lungs are _____ to the skin - ✔✔deep
