An advantage of gas exchange in water, compared with gas exchange in air is that water usually contains a higher conentrations of oxygen than air ventillation requires less energy in water the respiratory surfacd does not dryout in water the respiratory surface does not have to be as extensive in water O water is easier to move over the respiratory surface What does the release of adrenaline in the blood stimulate in the body? O increase sugar level in the blood increase heartbeat increase rate of respiration all of these Microorganisms that invade the body may be ingested by. antibodies white blood cells O red blood cells stem cells The function of the cerebellum is to: Ensure that the muscdes work together for smooth and coordinated movements Initiate visual reflexes and reaction to moving stimuli Receive sensory input from eyes, ears, joints and muscles Control cardiac, vasoconstrictor, and respiratory functions.
