  7. The chart below identifies the function of several organs found in a human body system. Which human body system performs these functions? (1) skeletal (3) circulatory (2) digestive (4) respiratory

  8. Explain the difference between arteries and veins. • Arteries carry blood AWAY from heart. Veins carry blood to the heart. • Arteries are larger, more muscular and elastic than veins. • Arteries carry blood under higher pressure than veins. • Veins have valves to prevent the backflow of blood. Arteries do not have valves.

  9. The exchange or diffusion of substances into or out of the capillary. Capillaries are extremely small and have a VERY thin lining that allows for diffusion to occur. Explain what occurs in capillaries and why.

  11. Identify the part of the heart being described. Chamber that receives oxygenated blood from the lungs. Wall that separates the right and left side of the heart. Large artery that carries oxygenated blood to the rest of the body. Chamber that pumps out deoxygenated blood to lungs. Left atrium Septum Aorta Right ventricle

  12. 5. Chamber that receives deoxygenated blood from the rest of the body. 6. Prevents the backflow of blood between atria and ventricles. 7. Chamber that pumps out oxygenated blood to the rest of the body. Right atrium Valves Left ventricle

  14. Which unit is used to express the amount of energy in food? • Calorie (2) milliliter (3) degree Celsius (4) gram

  15. 1.What system is represented in the diagram? 2. Identify labeled structures. Digestive Salivary glands Esophagus Liver Stomach Gall bladder Pancreas Small intestine Large intestine Appendix

  16. 3. Identify the function of those structures. A – Salivary glands B – Esophagus C – Stomach D – Pancreas E – Large intestine F – Appendix G – Small intestine H – Gall bladder I - Liver Produce saliva Pushes food to the stomach Chemical digestion of proteins, mechanical digestion Produces enzymes for chemical digestion in SI Absorbs water No function Chemical digestion, absorption of nutrients Stores bile Produces bile

  17. Peristalsis • Identify the process below. • Where in the digestive does it occur? Esophagus, stomach, small intestine, large intestine, rectum

  18. 1. Identify the type of digestion that occurs in the moth and stomach. A B C D

  19. Skeletal Cardiac Identify the muscle type described. • Attached to bones. • Involuntary and striated. • Lines the digestive tract and blood vessels. • Voluntary. • Only found in the heart. • Not striated and involuntary. • Branched fibers. Smooth Skeletal Cardiac Smooth Cardiac

  20. Identify each structure in the diagram and describe its function. Skeletal muscle: moves bones Ligament: connects bones Tendon: connects muscles to bines Bone

  21. Which statement describes ligaments? • They are made of cartilage and cushion the vertebrae. • They are made of tough, elastic tissue and join bones. • They are made of tough, inelastic tissue and connect muscles. • They are striped and controlled by the nervous system.

  22. The tissue that cushions the vertebrae and provides flexibility to joints is known as _______. cartilage

  23. Running to escape danger is an action that requires the nervous system to coordinate the interaction of which two body systems? (1) digestive and endocrine (2) muscular and skeletal (3) reproductive and excretory (4) circulatory and digestive

  24. The interaction of the skeletal and muscular systems to produce locomotion is coordinated by which human body system? • circulatory • nervous (3) excretory (4) respiratory

  25. What is bacteria an example of? Pathogen 2. Identify the structures labeled X in the diagram. Support your answer. Antibodies. They are proteins found on the surface of pathogens. X

  26. 3. Describe what occurs when this pathogen enters the body. Antibodies and memory cells are produced. Antibodies bind to the antigen to help destroy the pathogen. Memory cells remain in the blood to produce antibodies if exposed to the SAME pathogen. X

  27. Explain the contents of a vaccine. Dead or weak PATHOGEN

  28. How does a measles vaccine protect a child entering school against the measles? Vaccineis injected. The body produces antibodies and memory cells. Antibodies attach to antigens on the pathogen to help kill the pathogen. Memory cells remain in your blood to “remember” the pathogen.

  29. HIV (which is a virus) It weakens the immune system so the body cannot fight pathogens well. • What pathogen causes AIDS? • What is the effect of AIDS on the body?

  30. Infections may be caused by • mutations (2) toxic substances (3) microorganisms (4) climate changes

  31. Which health condition is an infectious disease? (1) pneumonia caused by microorganisms (2) heart problem caused by a high-fat diet (3) lung cancer caused by smoking (4) eye damage caused by ultraviolet light

  32. Scurvy is a disease that sailors often got on long voyages. It was discovered that scurvy could be prevented by eating oranges and lemons. This suggests that scurvy is a disease caused by • exposure to sea air (2) a microorganism (3) a nutritional deficiency (4) lack of exercise

  33. A student fails to eat a balanced diet over a period of time. This lack of a balanced diet can lead to • selective breeding (2) extinction (3) dynamic equilibrium (4) disease

  34. white blood cell Produce antibodies and engulf pathogens Y Z red blood cell platelet Carry oxygen Blood clotting Identify structures X, Y, and Z and their functions.

  35. Which part of the human blood: is the most numerous? contains a nucleus? is biconcave? is produced in the bone marrow? consists mainly of water? rbc’s wbc’s rbc’s rbc’s, wbc’s, platelets plasma

  36. Which part of the human blood transports hormones and nutrients? plasma platelets red blood cells white blood cells

  37. A cat jumps when startled by a loud noise. This is an example of an organism (1) sensing and responding to its external environment (2) sensing and responding to its internal environment (3) changing and controlling its external environment (4) changing and controlling its internal environment

  38. Identify the difference between the central nervous system and the peripheral nervous system. CNS consists of the brain and spinal cord. (interneurons) PNS consists of all nerves that extend away from the brain and spinal cord (sensory and motor neurons)

  39. Neuron • Identify the structure below. • Label all structures. A B D E C

  40. Impulse 3. Identify the message that travels through neurons. 4. Describe the nature of this message. Electrical and chemical

  41. In a simple spinal reflex, the pathway for an impulse is along a sensory neuron directly to a motor neuron through  (1.) a receptor  (2.) an interneuron  (3.) an effector  (4.) the brain

  42. Neurons that carry messages toward the CNS (brain and spinal cord) are called sensory neurons

  43. Neurons that carry messages away the CNS (brain and spinal cord) are called Motor neurons

  44. Why are reflexes much faster than a normal response? The impulse only travels to the spinal cord, not the brain.

  45. Insulin and glucagon are hormones that affect blood sugar levels. The diagram below shows the feedback system used by the human body to increase and decrease blood sugar levels. This feedback system is one way that the human body • circulates gases (3) destroys viruses (2) maintainsequilibrium (4) transports nutrients

  46. Identify the endocrine glands that produce insulin and glucagon. • Pancreas (Islets of Langerhans) • 2. Identify the function of insulin. • Lowers blood glucose levels • 3. Identify the function of glucagon. • Increases blood glucose levels

  47. The main function of hormones in the human body is to (1) identify and destroy microbes (2) regulate body functions (3) transport blood to cells (4) store energy

  48. In humans, the amount of sugar in blood is controlled by the release of a hormone called insulin. This process is an example of • depletion (3) regulation (2) digestion (4) excretion

  49. Which human organ system produces hormones to regulate growth, development, and reproduction? • circulatory (2) nervous (3) digestive (4) endocrine

  50. Kidneys A • Identify the labeled structures. • Identify the structure described. • Carries urine from the kidneys to the bladder. Ureters • Carries urine out of the body. Urethra • Produces urine. Kidneys • Stores urine. Urinary bladder B Ureters Urinary bladder C D Urethra
