13. 1. What is the name of the hormone that controls blood sugar levels? Insulin Glucagon

14. 2. What does the lens do? Carry nerve impulses Focus light rays

15. 3. What does the optic nerve do? Carry nerve impulses React to light

16. 4. What does the retina do? Focus the light React to light

17. 5. Why is it important for the eye to adjust to bright light? To prevent damage to the retina To react to light and focus

18. 6.How does the eye accommodate? lens changes shape using circulatory muscles/ suspensory ligaments to focus on objects at different distances lens changes shape using the cornea to focus on objects at different distances

19. 7. Why is poor eye accommodation a problem? Cannot judge depth so may cause a person to fall over due to lack of binocular vision cannot adjust focus quickly from close to distant objects because of weak muscles/stiff ligaments

20. 8. How do you treat a blocked coronary artery? Bypass surgery Artificial replacement

21. 9. How do you treat damaged heart valves? pacemaker Artificial replacement

22. 10. How does the pacemaker control the heartbeat? SAN sends or generates impulses causing atria to contract The pacemaker sends messages of electrical current through the heart

23. 11. What are the two types of pacemaker cells which control heart rate called? AVN and SAN AMS and NAV

24. 12. How does sweating cool the body? Vapourisation (requires kinetic/ energy) evaporation (requires heat / energy)

25. 13. What word describes keeping the body temperature constant? homeostasis insulation

26. 14. Breathing and heart rate remain high after exercise to...? Pump blood full of oxygen around the body to oxidise the muscles Break down lactic acid after anaerobic respiration

27. 15. S weat glands help to control the temperature of the body by… ? Releasing more sweat which evaporates taking heat from skin Releasing liquid/ plasma as part of a negative feedback mechanism

28. 16.Which part of the kidney regulates salt levels ? A: ascending loop of henle C: glomerulus

29. 17.Which area of the body controls the heart beat? hypothalamus pacemaker

30. 18. What hormone can alter heart rate? adrenaline testosterone

31. 19. What are the air sacs in the lungs called? villi alveoli

32. 20. How does oxygen enter the body? Diffusion from a high concentration to a low concentration Diffusion from a low concentration to a high concentration

33. 21. Why are alveoli thin? Short diffusion distance High concentration gradient

34. 22. How do you know B and C are arteries? They carry blood towards the heart They carry blood away from the heart

35. 23. Why do ventricles have thicker walls than atria? Greater force needed/ higher pressure needed Less force needed/ smaller pressure needed

36. 24. What happens if valves don’t work? Backflow is prevented Backflow is not prevented

37. 25. Why is it an advantage to have two ventricles (instead of one like fish)? Higher pressure is possible and better flow rate to tissues Higher pressure is possible and oxygenated and deoxygenated blood is separated

38. 26. What type of nerve takes signals to the muscles? Motor neurone Relay neurone

39. 27. What type of nerve takes signals away from the skin? Sensible neurone Sensory neurone

40. 28.Why must people be careful with prosthetic (artificial) limbs? They have no nerves so can’t feel pain They have too many nerves so are in constant pain

41. 29. What is diffusion? Particles concentrating so they can move through a net Net movement of particles from a high concentration to a low concentration

42. 30. What is the name of the condition when a person’s internal body temperature drops too low? hypothermia hyperthermia

43. 31.Why do people look red in the face when they get hot? Vasodilation of capillaries Vasoconstriction of capillaries

44. 32. What part of the brain monitors body temperature? hypothalamus hyperthermia

45. 33. How does vasodilation cool the body? It doesn’t, vasoconstriction cools the body- this is a trick question Brings blood to the surface of the skin so heat can escape

46. 34. How is a villus in the small intestine adapted for diffusion of food particles? Thin wall, large surface area Small, good blood supply

47. 35. Capillaries are better than arteries for diffusion because…? They are faster at diffusion and carry more blood They are thinner and there are lots of them

48. 36. You work out BMI using the following calculation…? Mass in kg divided by height in metres squared Height in metres squared divided by mass in kg

49. 37.If your BMI is 26, you are? overweight Just right

50. 38. Your daily recommended protein intake is known as your? RDA RPD

51. 39. Why doesn’t everyone eat animals like chickens etc? They might choke on the fur or beak Religion or ethical reasons

52. 40. What does the cornea do? Refracts light Reflects light

53. 41. What is the iris for? To look nice and colourful Adjust levels of light reaching the retina

54. 42. Why do some people need a lens replacement? So the focused image lands correctly on their retina The lenses on their glasses are too dirty to see through

55. 43.One way of curing short sight is? Laser surgery A convex lens

56. 44. What causes colour blindness? Genetic/ hereditory Not being able to tell the difference between reds and greens

57. 45.Name one simple sugar? starch glucose

58. 46. What food group do sugars belong to? carbohydrates fats

59. 47. Where does glucose enter the blood stream? Cilia in the colon Small intestine

60. 48. What does insulin do? Converts glucose to glycogen Converts glucagon to glycogen

61. 49.Where does insulin work? Mostly the liver and muscles Mostly the pancreas and liver

62. 50. Insulin…? Converts glucose to glycogen Breaks down glucose to glycogen
