1. Excretory and Respiratory Systems Review

2. 1.Identify A, B, and D. lung liver kidney

3. Which organ produces urea? What is the function of D? B - liver Filter wastes from blood Regulate water concentration of blood. Produce urine

4. What does organ A excrete? Which organ detoxifies the blood? CO2 and H2O vapor B - Liver

5. What are metabolic wastes? Examples? Wastes from your cells. CO2, H2O, salts, urea

6. Identify structures A, B, C, and D. Kidney Ureter Urinary bladder Urethra

7. Which structure produces urine? What is the path of urine? A - Kidneys Kidneys  ureters  urinary bladder  urethra

8. What stores urine? What is the function of D? C - Urinary bladder Releases urine from the body.

9. Which human excretory structure aids in the maintenance of normal body temperature? Why is the skin also an excretory organ? Skin It excretes water, salts and small amounts of urea in the form of perspiration.

10. Identify the structures labeled in the diagram. A – nasal cavity B – pharynx C – larynx D – trachea E – bronchi F – bronchioles G – lung H - diaphragm A B C D E F G H

11. Explain the function of the respiratory system. To carry out gas exchange between the external and internal environment A B C D E F G H

12. Identify the structure described. 1. Contain a ciliated mucus membrane 2. Voice box 3. Aids in breathing 4. Throat 5. Windpipe A B C D E F G H Nasal cavity and trachea larynx diaphragm pharynx trachea

13. Which is the correct sequence for the path of oxygen through the respiratory system? Nasal cavity Pharynx Larynx Trachea Bronchi Bronchioles Alveoli

14. 1. The tubes that branch from the trachea are the 2. The dome shaped muscle below the chest cavity is called the 3. During swallowing, the air passage of the pharynx is covered by the 4. Alveoli in the lungs are connected to the bronchi by a network of tiny tubes called 5. Breathing is controlled by the chemistry of your blood as it interacts with the bronchi diaphragm epiglottis bronchioles carbon dioxide

15. Explain what happens to gases during gas exchange in the alveoli. Oxygen in alveoli diffuses into capillaries (blood). Carbon dioxide in capillaries (blood) diffuses into alveoli.

16. 1. Where are the vocal cords located in the body? 2. Breathing is an involuntary process controlled by the which part of the brain? 3.What prevents the trachea from collapsing? 4.Where does the actual exchange of gases occur? 5.During gas exchange where does the oxygen and carbon dioxide go? larynx medulla rings of cartilage alveoli O2 diffuses into capillaries. CO2 diffuses out of capillaries and into alveoli.

17. The ______ is a long straight tube that carries air from the back of the throat to the lungs. trachea

18. What structures trap foreign particles and bacteria in the nose and trachea? a)pharynx b)epiglottis c)cilia d)trachea

19. The order of air movement with in the lungs is best described as a)bronchioles to bronchi to alveoli b)bronchi to bronchioles to alveoli c)trachea to bronchi to alveoli d)bronchi to alveoli to bronchioles

20. Where are the vocal cords located in the body? Larynx

21. During swallowing, the air passage of the pharynx is covered by the epiglottis

22. The FIRST branches off the trachea are called bronchi

23. What prevents the trachea from collapsing? rings of cartilage

24. The dome shaped muscle below the chest cavity is called the diaphragm

25. Alveoli in the lungs are connected to the bronchi by a network of tiny tubes called a)arterioles b)venules c)capillaries d)bronchioles

26. Inside the alveoli, carbon dioxide and oxygen a)are transported along microscopic tubules b)are exchanged between air and blood c)are produced inside cells d)are exchanged for other gases

27. Humans breathe more rapidly during exercise than before it because during exercise the blood contains 1.an increased level of oxygen 2.a decreased number of red blood cells 3.an increased level of carbon dioxide 4.a decreased amount of hemoglobin

28. Breathing is controlled by the chemistry of your blood as it interacts with the part of the brain called the medulla

29. Breathing is an involuntary process controlled by the amount of ____ in your blood. carbon dioxide

30. What happens to each of the following during inhalation? Diaphragm Rib cage Pressure in chest cavity contacts (pulls down) expands decreases

31. What happens to each of the following during exhalation? Diaphragm Rib cage Pressure in chest cavity relaxea (moves up) relaxes increases
