Answers |Accurate|Verified
lymphatic system - correct answers--picks up fluid leaked from blood
vessels and returns it to blood.
-disposes of debris in the lymphatic stream.
-houses white blood cells (lyphocytes) involved in immunity.
-the immune response mounts the attack against foreign substances within
the body.
nervous system - correct answers-responds to internal and external
changes by activating appropriate muscles and glands.
digestive system - correct answers-breaks down food into absorbable units
that enter the blood for distribution to body cells.
cardiovascular system - correct answers-blood vessels transport blood
which carries oxygen, carbon dioxide, nutrients, water, etc.
respiratory system - correct answers-keeps blood constantly supplied with

what is negative feedback? - correct answers-a reaction in which the system
responds in such a way as to reverse the direction of change
examples of negative feedback: - correct answers-- thermoregulation
-home heating system
-blood glucose level
what is positive feedback? - correct answers-a response is to amplify the
