Frage 20
Frage
A Receptor
(ie feedback system)
Antworten
-
is a body structure that monitors changes in a controlled condition and sends input to a control center.
(example, the pancreas detects low blood glucose in the blood.)
-
in the body, for example, the brain, sets the range of values within which a controlled condition should be maintained
-
reverses a change in a controlled condition
-
tends to strengthen or reinforce a change in one of the body’s controlled conditions
Frage 21
Frage
A Positive Feedback System
may be more then one right answer;
Antworten
-
tends to strengthen or reinforce a change in one of the body’s controlled conditions
-
does not occur often in a controlled system
-
reverses a change in a controlled condition
-
is a body structure that monitors changes in a controlled condition and sends input to a control center
-
an example would be during childbirth contractions of the wall of the uterus force the baby’s head into the cervix, stretching the cervix. Stretch receptors detect this and send signals to the brain which releases the hormone oxytocin. Oxytocin makes the muscles of the uterus contract even harder, forcing the baby deeper into the cervix which causes even more stretching of the cervix.

Frage 23
Frage
The body regulates its [blank_start]internal[blank_end] environment using [blank_start]two types[blank_end] of [blank_start]feedback systems[blank_end]. A feedback system, or [blank_start]feedback loop[blank_end], is a [blank_start]cycle of events[blank_end] in which a body [blank_start]condition[blank_end] is [blank_start]monitored[blank_end], evaluated, changed, and adjusted accordingly. Each factor being monitored, such as body temperature, blood pressure, or blood glucose level, is [blank_start]termed a controlled condition[blank_end]. Any disruption that changes a controlled condition is called a stimulus. For example, the body tightly regulates how much glucose is in the blood. If there is [blank_start]too little[blank_end], energy reactions may not take place efficiently. If there is [blank_start]too much[blank_end], glucose can damage blood vessels.
