Students have asked these similar questions
a positive-feedback system is one in which
a. a variable is charged in the opposite direction to the original change that initiated the system
b. a variable is changed in the same direction as the original change that initiated the system
c. two opposiding variables are played against each other
d. the initiating variable is always increased
Which of the following physiologlcal responses is an example of positive feedback?
. The body's production of red blood cells, which transport oxygen from the lungs to other organs,
is stimulated by low concentrations of oxygen.
b. A high concentration of glucose in the blood causes deeper, more rapid breathing, which expels
carbon dioxide.
C. Pressure of the baby's head near the opening of the uterus stimulates uterine contractions
which cause greater pressure against the uterine opening.
d. Heightened body temperature induces sweating which disposes of metabolic heat and cools the
body.

A. Adipose. B.Cartilage. C.Bone. D. Dense connective tissue. E.Loose connective tissue
2. According to Frank-Starling law of the heart,
A.increased preload causes increased cardiac output. B.increased afterload causes increased cardiac output. C.decreased preload causes increased afterload. D.afterload influences cardiac output more than preload. E.cardiac output is not influenced by preload.

Its secretion is controlled by a negative-feedback system between the concentration of glucose in the blood and the insulin-secreting cells. Therefore, which of the following statements is correct? A decrease in blood glucose concentration stimulates insulin secretion, which in turn further towers blood glucose concentration. An increase in blood glucose concentration stimulates insulin secretion, which in turn lowers blood glucose concentration. A decrease in blood glucose concentration stimulates insulin secretion, which in turn increases blood glucose concentration. An increase in blood glucose concentration stimulates insulin secretion, which in turn further increases blood glucose concentration. None of the preceding is correct.arrow_forward
