Unit 6.1 Test Review THE NERVOUS, INTEGUMENTARY, CIRCULATORY, AND RESPIRATORY SYSTEMS

Transcription

1 Name: Period: Due Date: Unit 6.1 Test Review THE NERVOUS, INTEGUMENTARY, CIRCULATORY, AND RESPIRATORY SYSTEMS The Nervous System: 1. Name the 3 parts of a neuron and their function: a. b. c. 2. What is the space between nerve cells called? 3. What is the function of the nervous system? 4. What does CNS stand for? Then explain CNS main parts and functions: 5. What does PNS mean and what does it include? 6. Why is the front of the brain so wrinkled? 7. What does the left hemisphere of the brain control? 7. What does the right hemisphere control? 8. What is the difference between the rods and cones in your eye?

2 The Integumentary System 1. What are the 5 functions of the Integumentary System? a. b. c. d. e. 2. Label the layers or part of the skin cross section: A: B: C: 3. What layer of the skin has the blood vessels? 4. What is the name of the pigment that gives skin its color?

3 The Circulatory System 1. In pulmonary circulation, blood flows through which two organs? 2. What are valves responsible for? 3. What 3 main factors help blood moves through the veins? a. b. c. 4. What are the three types of blood vessels? What are their functions and oxygen levels? Blood Vessel Function Artery Veins Capillaries Note: The pulmonary veins carry oxygenated blood from the lungs back to the heart where it is then pumped throughout the rest of the body 5. Why does our heart rate change? 6. Label the types of blood cells: A B C Part Function carry needed materials like oxygen and glucose, CO 2 fight disease involved in blood clotting

4 7. What is the main function of the circulatory system? 8. Label the Heart: A Part Blood Flow (rich or poor O 2)or Function Oxygen rich blood flows into this artery from the left ventricle. It then flows out to the body. B Oxygen rich blood returns from the lungs. It then flows into this chamber C D E F G Prevent blood from flowing backwards. Oxygen rich blood flows from here into the aorta. Separates the oxygen poor blood from the oxygen rich blood. Oxygen poor blood flows from here to the lungs. Oxygen poor blood returns from the body. It then flows into here 9. Use red/blue colored arrows to show the flow of blood and indicate oxygenated vs. deoxygenated blood: 10. List the order the blood flows through the heart:

5 The Respiratory System 1. What is the path that air takes when it enters the body? List the order: 2. Label the Respiratory System: A B C D E F G Part Function Air moves from the nose downward into this tube. Also known as your throat. Plays a role in producing your voice. Also known as your voice box. Leads from the pharynx to the lungs Air moves through smaller and smaller bronchi until it reaches the alveoli Dome shaped muscle that helps expand and contract the chest cavity Air moves from the trachea into the right and left bronchus. This is the site of exchange of oxygen and carbon dioxide 3. Give a brief explanation of the process of breathing. Then explain what happens when you inhale and then exhale - Process of Breathing: What happens when you Inhale: What happens when you Exhale: 4. What is respiration? 5. There are two types of respiration, list and explain them: 6. How do the circulatory and respiratory systems work together in gas exchange to help the body maintain homeostasis?

6 7. Use the graph to answer the questions: a. What is the approximate heart rate for the office worker at 4 minutes? b. What is the approximate heart rate for the athlete at 4 minutes? c. Why does the heart rate increase after exercise? d. What are the variables in the graph? What to study and studying tips: 1. A week before the test, starting going through the notes (both your own and the powerpoints posted on my website) and fill out this test review. Use your textbook too! 2. The ideal method is to spend some time every night reviewing material, not to do it all at one time. 3. Highlight key words, especially scientific vocabulary know these terms!! 4. Ideas for review: make flashcards, make a quizlet, or find some other way to quick quiz yourself! 5. Look over warm ups posted online warm up questions are VERY similar to test questions. 6. Utilize tools at your disposal: teacher website on the unit page, at the bottom, is the unit review section. Check out these videos and other links to help you understand topics you are weak in. Above all ask questions when you do not understand the material!
