Which of the following is not an aspect that could result in physiological variation?
A) Age
B) Gender
C) Environment
D) Physical activity
E) These are all aspects that can cause physiological variation.
We live in an ever-changing environment outside of our body, yet our internal conditions
remain relatively stable. This is called .
A) homeostasis
B) metastasis
C) responsiveness
D) adaptation
E) evolution
What are the three common components of a feedback loop?
A) Stimulus, integrating (control) center, and organ system
B) Stimulus, receptor, and integrating (control) center
C) Receptor, integrating (control) center, and effector
D) Receptor, organ, and organ system
E) Receptor, integrating (control) center, and organ system
Negative feedback is a self-amplifying chain of events that tends to produce rapid change in
the body.
true
false
62) During exercise, one generates excess heat and the body temperature rises. As a response,
blood vessels dilate in the skin, warm blood flows closer to the body surface, and heat is lost.
This is an example of _____________.
A) negative feedback
B) positive feedback
C) dynamic equilibrium
D) integration control
E) set point adjustment
, Blood glucose concentration rises after a meal and stimulates the pancreas to release the hormone
insulin. Insulin travels in the blood and stimulates the uptake of glucose by body cells from the
bloodstream, thus reducing blood glucose concentration. This is an example of .
A) negative feedback
B) positive feedback
C) dynamic equilibrium
D) integration control
E) set point adjustment
Negative feedback loops are ________.
A) homeostatic mechanisms
B) not homeostatic mechanisms
C) associated with "vicious circles"
D) self-amplifying cycles
E) usually harmful
Positive feedback helps to restore normal function when one of the body's physiological
variables gets out of balance.
true
false
When a woman is giving birth, the head of the baby pushes against her cervix and stimulates
the release of the hormone oxytocin. Oxytocin travels in the blood and stimulates the uterus to
contract. Labor contractions become more and more intense until the baby is expelled.
This is an example of .
A) negative feedback
B) positive feedback
C) dynamic equilibrium
D) integration control
E) set point adjustment
Which of the following is most likely to cause disease?
A) Positive feedback
B) Negative feedback
C) Homeostasis
D) Equilibrium
E) Irritability
A physiological _________ is a difference in chemical concentration, electrical charge,
physical pressure, temperature, or other variables between one point and another.
A) gradient
B) barrier
C) membrane
D) imbalance
E) feedback loop
