What is the job of the platelets? __________________________________________________________________ __________________________________________________________________ 10. What is lymph? __________________________________________________________________ __________________________________________________________________ 11. The following sentences describe the path of blood through the circulatory system. In the space provided, write a 1 next to the sentence that describes what happens first. Continue until all sentences are numbered. The cycle begins with the blood flowing from the lungs to the heart. _____ Blood is pumped from the right atrium to the right ventricle. _____ Blood is pumped from the body to the right atrium. _____ Blood is pumped from the left ventricle to the rest of the body. _____ Blood is pumped from the right ventricle to the lungs. _____ Blood is pumped from the left atrium to the left ventricle. _____ Blood is pumped from the lungs back to the left atrium.

An automatic response to stimuli is called a _________________________. 3. ______________________________ is the major organ in the nervous system. 4. ______________________________ is the part of the brain that makes your muscles work together; controls most movements that you do without thinking. 5. The largest part of the brain where most of your thinking takes place is the ____________________________. 6. __________________________ is a bundle of cells that conducts messages from one part of the body to another. 7. __________________________ are two halves of a sphere, or ball-shaped object, such as the brain 8. The organ that carries messages to and from the brain is known as the __________________________. Lesson 7 - Nervous System Comprehension Read the paragraphs. Then answer the questions. Melanie’s class was studying the nervous system. They read that the cerebrum is the part of the brain that solves problems and makes decisions. It receives and answers messages from the senses. They also read that the cerebellum helps people move and keep their balance. The cerebellum directs movements so well that people usually do not have to think about moving at all. In addition, they read that the brain stem takes care of breathing, heartbeat, and swallowing. People do not have to think about these functions either. Later that day at home, Melanie saw a bright red strawberry on a white dish. She put it in her mouth and bit into it. The strawberry’s juice ran onto her tongue and down into her esophagus as she swallowed. Suddenly, Melanie ran to the sink and spit out the piece of strawberry. 1. What part of Melanie’s brain told her the strawberry was red? ______________ 2. What facts support your answer? __________________________________________________________________ 3. What part of Melanie’s brain directed the juice from the strawberry to go into her esophagus? __________________________________________________________________ 4. What facts support your answer? __________________________________________________________________ 5. Why do you think Melanie spit out the strawberry? __________________________________________________________________ 6. What part of her brain told her that? __________________________________ 7. What part of her brain controlled her as she ran to the sink? ________________ 8.
