3 THE RESPIRATORY SYSTEM

4 RESPIRATION ENERGY-RELEASING PROCESS THAT IS FUELED BY OXYGEN YOU BREATHE 6 LITERS PER MINUTE REMOVES THE WASTE PRODUCT CARBON DIOXIDE

5 NOSE AND THROAT AIR ENTERS THROUGH NOSTRILS – OPENINGS IN THE NOSE IT FLOWS TO THE NASAL CAVITY –HEATED BY BLOOD VESSELS –MUCUS MOISTENS THE AIR AND TRAPS DUST PARTICLES AND MICROSCOPIC ORGANISMS

6

7 A FRESH BATCH OF MUCUS IS PRODUCED EVERY 20 MINUTES CILIA PUSH OLD MUCUS TOWARD THE ESOPHAGUS AND INTO THE STOMACH –HYDROCHLORIC ACID DESTROYS MANY BACTERIA TRAPPED IN THE MUCUS

8 SNEEZE SOME PARTICLES NEVER MAKE IT PAST THE NOSE BECAUSE THEY ARE SNEEZED OUT

9

10 EPIGLOTTIS SMALL FLAP OF TISSUE THAT CLOSES OVER THE ENTRANCE OF THE RESPIRATORY SYSTEM WHEN FOOD AND WATER ARE INGESTED

11 EPIGLOTTIS

12 TRACHEA KNOWN AS THE WINDPIPE BUMPS ARE RINGS OF CARTILAGE –FLEXIBLE SO YOU CAN BEND YOUR NECK

13 –RIGID TO KEEP THE AIR PASSAGE OPEN –HELD TOGETHER BY SMOOTH MUSCLE THAT ENABLES THE DIAMETER TO BE CHANGED

14

15 MUCUS TRAPS PARTICLES AND BACTERIA THAT MANAGE TO GET PAST THE NOSE –SWEPT OUT OF TRACHEA AND UP TO THE MOUTH OR NOSE BY CILIA –IF PARTICLES COLLECT – YOU COUGH

16 LARYNX VOICE BOX – LOCATED AT TOP OF TRACHEA MADE OF CARTILAGE THAT JETS OUT OF THE NECK (ADAM’S APPLE) –LARGER IN MALES BECAUSE THEY GENERALLY HAVE LESS FAT

17 MRI OF LARYNX

18 VOCAL CORDS TWO SMALL FOLDS OF TISSUE THAT STRETCH ACROSS THE LARYNX MUSCLES TIGHTEN TO NARROW THE SLIT BETWEEN THEM

19 RUSHING AIR MAKES THEM VIBRATE –HIGH VOICE – TIGHTER CORDS- VIBRATE RAPIDLY –LOW VOICE – MORE RELAXED – VIBRATE MORE SLOWLY

20 VOCAL CORDS

21 PITCH IS DETERMINED BY SIZE OF LARYNX AND LENGTH OF VOCAL CORDS

22 TONGUE, LIPS, AND TEETH PLUS THE VIBRATION IN THE NASAL CAVITY GIVE YOUR VOICE A SPECIAL QUALITY

23 LUNGS

24 BRONCHI TWO TUBES THAT BRANCH OFF OF THE TRACHEA INTO EACH LUNG

25 LARYNXWINDPIPE BRONCHI

26 LUNGS MAIN ORGAN OF RESPIRATION BRONCHI CONTINUE TO DIVIDE IN THEM

27 ALVEOLI SACS AT ENDS OF THE BRONCHIAL TUBES GATEWAYS FOR OXYGEN INTO THE BODY

28

29 600 MILLION IN LUNGS SURROUNDED BY CAPILLARIES AS AIR ENTERS THE ALVEOLI, OXYGEN SEEPS THROUGH THE THIN WALLS INTO SURROUNDING CAPILLARIES BLOOD CARRIES IT THROUGHOUT THE BODY CARBON DIOXIDE IS EXCHANGED IN THE SAME WAY

30

31

32 2400 KILOMETERS OF AIRWAYS FIT INTO THE CHEST CAVITY –CARBON DIOXIDE AND OXYGEN IS EXCHANGED IN A FEW SECONDS

33 BREATHE YOU BREATHE ABOUT 1 LITER OF AIR EVERY 10 SECONDS AT REST

34 DIAPHRAGM DOME-SHAPED MUSCLE CONTRACTS TO BREATHE IN –ALLOWS CHEST TO EXPAND

35 –EXPANSION ALLOWS MORE ROOM FOR AIR IN YOUR LUNGS –AIR PRESSURE INSIDE DECREASES ALLOWING AIR TO RUSH IN FROM OUTSIDE

36 EXHALE – DIAPHRAGM RETURNS TO NORMAL –SPACE DECREASES IN CHEST CAVITY –AIR PRESSURE INCREASES –AIR IS FORCED OUT

37

38 THE DIAPHRAGM CAN BE CONTROLLED OR WORK AUTOMATICALLY

39 HICCUP DIAPHRAGM BECOMES IRRITATED – THE VOCAL CORDS SNAP SHUT INCREASED LEVELS OF CARBON DIOXIDE WILL CAUSE INVOLUNTARY CONTRACTIONS TO STOP –STOPS THE HICCUPS

40 THE EXCRETORY SYSTEM

41 EXCRETION PROCESS IN WHICH WASTE IS REMOVED FROM THE BODY

42 THE KIDNEYS ACT AS BODY’S FILTER – REMOVES WASTE AND POISONS FROM THE BLOOD REDDISH BROWN AND SHAPED LIKE KIDNEY BEANS

43 ONE KIDNEY ON EACH SIDE OF SPINAL COLUMN JUST ABOVE THE WAIST 1 LITER OF BLOOD IS RECEIVED EACH MINUTE

44

45 UREA NITROGEN WASTE FILTERED OUT OF THE BLOOD BY THE KIDNEYS

46 PARTS OF THE KIDNEY

47 NEPHRON WHERE ACTUAL FILTERING TAKES PLACE MILLIONS OF CHEMICAL FILTERING FACTORIES

48 CAPSULE

49 CUP-SHAPED PART OF THE NEPHRON CARRIES FILTERED MATERIALS TO TINY TWISTING TUBE

50 –MOST NUTRIENTS, SALTS AND WATER ARE REABSORBED –LIQUID REMAINING IS URINE –URINE IS 90% WATER

51 IF THE BODY DID NOT REABSORB MOST OF THE NUTRIENTS, SALTS AND WATER IT WOULD DIE

52 URETER THE NARROW TUBE THAT CONNECTS THE KIDNEYS TO THE URINARY BLADDER YOU HAVE TWO URETERS – ONE FROM EACH KIDNEY TO THE BLADDER

53 URINARY BLADDER MUSCULAR SAC THAT STORES URINE BEFORE IT IS RELEASED

54 URINARY BLADDER

55 BLADDER STONE

56 URETHRA CONNECTS URINARY BLADDER TO THE BODY EXIT

57

58 OTHER EXCRETORY ORGANS

59 LIVER REMOVES WASTE FROM THE BODY REMOVES EXCESS AMINO ACIDS – FORMS UREA

60 CONVERTS HEMOGLOBIN FROM WORN-OUT RED BLOOD CELLS INTO BILE –BILE REMOVES AND DIGESTS MOST BACTERIA THAT ENTER FROM THE LARGE INTESTINE

61 SKIN 1.5 TO 2 SQUARE METERS – IT IS THE LARGEST ORGAN 0.5 TO 6 MILLIMETERS IN THICKNESS

62

63 EPIDERMIS TOP LAYER DEAD, FLATTENED CELLS THAT ARE CONSTANTLY SHED

64 INNERMOST LAYER CONTAINS LIVING, ACTIVE CELLS THAT PRODUCE MORE CELLS NO NERVES OR BLOOD VESSELS

65 DERMIS BOTTOM LAYER CONTAINS NERVES AND BLOOD VESSELS THICKER THAN EPIDERMIS

66 CONTAINS SMALL FINGERLIKE STRUCTURES – EPIDERMIS ON TOP CREATES RIDGES –RIDGES ARE FINGERPRINTS

67 SKIN ALSO CONTAINS HAIR, NAILS, SWEAT AND OIL GLANDS –HAIR AND NAILS ARE FORMED FROM SKIN CELLS THAT ARE FILLED WITH A TOUGH, FIBER-LIKE PROTEIN AND THEN DIE

68

69 SWEAT OR PERSPIRATION WASTE EXCRETED THROUGH THE SKIN

70 SWEAT GLANDS COILED TUBES CONNECTED TO PORES –HELP BODY GET RID OF EXCESS SALT, UREA AND ABOUT 0.5 LITERS OF WATER EVERY DAY THIS COMBINATION IS KNOWN AS SWEAT OR PERSPIRATION

71 SWEAT NOT ONLY RIDS THE BODY OF WASTES, IT HELPS REGULATE THE BODY TEMPERATURE –EVAPORATES FROM THE BODY’S SURFACE STRENUOUS EXERCISE – 10 LITERS IN 24 HOURS
