Biology TEKS Correlations
(10) Science concepts. The student knows that, at all levels of nature, living
systems are found within other living systems, each with its own boundary and
limits. The student is expected to:
(B)compare the interrelationships of organ systems to each other and to the body as a whole; and
25.

On a hot day an athlete becomes sweaty and flushed while jogging outdoors. However, the athlete’s internal
body temperature remains near normal. Which statement best explains these observations?
A.
B.
C.
D.
Internal body temperature is controlled by the respiratory system.
A physically fit person forces the organ systems to maintain internal body temperature.
The organ systems work together to keep internal body temperature constant.
Internal body temperature is dependent on the temperature of the environment.
This item illustrates understanding how the organ systems function together to maintain
homeostasis, which is a part of Biology TEKS (4)(B) and (11)(A).
