Nervous system: label the following: sensory neurons, effectors, stimuli, spinal cord, motor neurons, interneurons, receptors, reaction. Then describe what is happening in this diagram using all the words mentioned, plus add brain, peripheral nervous system, and central nervous system. Underline all the words you used in your paragraph.
Respiratory system: Label all the following numbers: 1, 2, 8, 4, 5, 10, 11, and 6
Circulatory System: Label all the following numbers. Color the parts of the heart BLUE that are deoxygenated and color the parts of the heart RED that are oxygenated. Think carefully before you color!
Write name of the structures that explains how blood flows through the heart. Start as oxygen-depleted blood that is about to enter the heart from the structure labeled 7 and 14.
