Section 2: Structures and 2.78B describe the role of ADH in regulating the water 127-128 functions in living content of the blood organisms 2.79B understand that urine contains water, urea and i) Excretion ions. Section 2: Structures and 2.80 understand how organisms are able to respond to 138 changes in their environment functions in living organisms 144-146 2.81 understand that homeostasis is the maintenance of a j) Coordination and constant internal environment, and that body water content response and body temperature are both examples of homeostasis 2.82 understand that a co-ordinated response requires a stimulus, a receptor and an effector. Section 2: Structures and 2.83 understand that plants respond to stimuli functions in living organisms 2.84 describe the geotropic and phototropic responses of roots and stems j) Coordination and response understand the role of auxin in the phototropic 2.85 response of stems. Section 2: Structures and 2.86 describe how nervous and hormonal communication 146 functions in living control responses and understand the differences between the two systems 139 organisms j) Coordination and 2.87 understand that the central nervous system consists of response the brain and spinal cord and is linked to sense organs by nerves 138-140 2.88 understand that stimulation of receptors in the sense organs sends electrical impulses along nerves into and out of the central nervous system, resulting in rapid responses 2.89 understand the role of neurotransmitters at synapses 140-141
