  1. COMPARATIVE ANATOMY

  2. Body Organization Body Organization This diagram tracks the levels of organization in the body. What are the missing level names?

  3. Skeletons and Muscles How are endoskeletons and exoskeletons alike and how they are different?

  4. Skeletons and Muscles Endoskeletons Endoskeletons are made of different materials.

  5. Skeletons and Muscles Muscle Pairs Which muscle is relaxed or contracted in each type of skeleton?

  6. The Skeletal System Movable Joints Movable joints allow movement in different ways. What is another joint for each type?

  7. The Muscular System Muscle Use How is the person in each frame using involuntary and voluntary muscles?

  8. The Muscular System Compare and Contrast How are all three muscle tissues alike and how are they different?

  9. The Skin Structures of the Skin What are the functions of the epidermis, the nerves, and the sweat gland?

  10. How Animals Obtain and Digest Food Obtaining Food The snail's radula is a flexible, tonguelike ribbon of tiny teeth.

  11. How Animals Obtain and Digest Food Digestive Tubes The digestive tubes of earthworms and fishes have specialized areas in common.

  12. The Digestive Process Begins Digestive System Organs Food passes directly through five of the organs of the digestive system.

  13. The Digestive Process Begins The Mouth Digestion begins in the mouth.

  14. Final Digestion and Absorption Organs of Digestion The liver, pancreas, and gallbladder produce and store substances that aid digestion. What is the function of each organ?

  15. Final Digestion and Absorption Villi Tiny villi line the folds of the small intestine.

  16. Final Digestion and Absorption There are many different parts to the body’s digestive system.

  17. Circulation and Excretion A Closed Circulatory System An earthworm’s body is divided into more than 100 segments. The earthworm’s circulatory system runs through all of the segments.

  18. Circulation and Excretion Heart Chambers In fishes, the heart has two chambers—one atrium and one ventricle.

  19. Circulation and Excretion A Single-Loop Pattern What happens to oxygen and carbon dioxide in the gills and body organs? Where are the atrium and the ventricle?

  20. Circulation and Excretion A Double-Loop Pattern What type of blood is in each heart chamber?

  21. The Body’s Transport System The Cardiovascular System Like roads that link all the parts of a town, the cardiovascular system links all the parts of the body.

  22. The Body’s Transport System The Heart

  23. The Body’s Transport System Two Loops The heart can pump 5 liters of blood through the two loops each minute. What is the path the blood travels?

  24. A Closer Look at Blood Vessels What are the functions and structures of the blood vessels? What would be a title for the table?

  25. A Closer Look at Blood Vessels Blood Vessels What happens to blood in each kind of vessel?

  26. Composition of Blood Cells in Blood In addition to red and white blood cells, blood contains platelets, the fragments of cells. What is the function of each component? Where are blood cells produced?

  27. Composition of Blood Blood Types and Their Markers What are the rest of the marker molecules and clumping proteins?

  28. Composition of Blood Blood Types in the United States The circle graph shows the distribution of each blood type in the population of the United States.

  29. Composition of Blood The Lymphatic System Fluid moves out of capillaries into the lymphatic system, and then returns to the bloodstream. What are the roles of the parts of the lymphatic system?

  30. How Animals Obtain Oxygen Compare and contrast breathing and cellular respiration.

  31. How Animals Obtain Oxygen Respiration Without Lungs Animals that live in water and do not have lungs use their outer body covering or gills to exchange gases. What are the animals' respiratory structures?

  32. How Animals Obtain Oxygen Invertebrate Respiration Skin, book lungs, and tracheal tubes are respiratory structures of invertebrates.

  33. How Animals Obtain Oxygen Lungs How do pockets increase a lung's surface area?

  34. How Animals Obtain Oxygen A Bird’s Lungs What is the path air takes through a bird's respiratory structures?

  35. The Respiratory System Structures of the Respiratory System Particles in the air are filtered out as the air moves through the respiratory system. What does each part of the respiratory system do?

  36. The Respiratory System Gas Exchange Gases move across the thin walls of both alveoli and capillaries.

  37. Kidney Ureter Urinary bladder Urethra The Excretory System The Excretory System Urine is produced in the kidneys and then travels through the excretory system.

  38. The Excretory System How the Kidneys Work Most of the work of the kidneys is done in the nephrons.

  39. The Nervous System Nervous Systems Different types of nervous systems have different functions.

  40. Dendrites Cell body Nucleus Axon Myelin Axon tips How the Nervous System Works Structure of a Neuron A neuron has one axon and many dendrites that extend from the cell body.

  41. Divisions of the Nervous System The Nervous System Explain the function of each part of the nervous system.

  42. Divisions of the Nervous System The Brain

  43. Divisions of the Nervous System The Cerebrum The cerebrum is divided into a right and a left half.
