10734422440What is homeostasis?the ability to maintain a relatively stable internal environment in an ever-changing outside world61
10734422441What 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 output62
10734422442What is negative feedback within homeostasis? and examplethe response reduces or shuts off the original stimulus regulation of body temp (nervous mechanism) regulation of blood volume by ADH (endocrine mechanism)63
10734422443What 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 these64

10734422445Why 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 life66
10734422446What's the process of negative back for regulation of blood volume by ADHReceptors 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.67
10734422447What is positive feedback examplesthe 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 clotting68
10734422448Homeostatic 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)69
10734422449the head is _______ to the abdomensuperior70
10734422450the navel is ______ to the chininferior71
10734422451the breastbone is _____ to the spineanterior (ventral)72

10734422459the lungs are _____ to the skindeep80
10734422460What process allows us to adjust to either extreme heat or extreme cold?Negative feedback mechanisms allow us to adjust to conditions outside the normal temperature range by causing heat to be lost from the body and retained or generated by the body.81
10734422461When we begin to get dehydrated, we usually get thirsty, which causes us to drink fluids. Is thirst part of a negative or a positive feedback control system?thirst is part of a neg. feedback control system because it prods us to drink which ends the thirst stimulus and returns body fluid volume to the normal range82
10734422462Why is the formation of platelet plug called positive feedback? What event ends it?This is a pos. feedback mechanism because it enhances the change set into motion by the stimulus. The response ends when the platelet plug has plugged the hole in the blood vessel.83

10734422494When you rub your cold hands together, the friction between them results in heat that warms your hands. why doesnt warming friction result during movements of the heart, lungs and digestive organsAs mobile organs work fiction is greatly reduced by the presence of seours flued. seous fluid allows the surrounding serous membranes to glide easily over one another110
