  37. AV valves
    • open during heart filling phase “diastole” allowing
    • ventricles to fill with blood. Close during heart pumping stage “systole” av
    • valves close to prevent regurgitation of blood. Papillary muscles contract at
    • this time, so that leaflets meet and unite to form a perfect seal withouth
    • turning inside out
  38. Semilunar valves

  42. Blood flow through heart:
    Blood flow through heart: Liver->inferior vena cava->

    Head and upper extremities->superior vena cava->

    • ->right atrium->tricuspid valve->right
    • ventricle->pulmonic valve->pulmonary

    • artery->lungs->pulmonary veins-> left
    • atrium->mitral valve-> left ventricle-> aortic

    valve-> aorta-> body
  43. cardiac cycle
    rhythmic movement of blood flow through the heart
  44. Diastole
    • ventricles relax and fill with blood, this takes up 2/3 of
    • cycle. AV valves open (Acoustically silent), pressure in atria is higher then
    • in ventricles so blood pours rapidly into ventricles.
  45. first passive filling phase is called early or protodiastolic filling.
    • *first passive filling phase is called early or
    • protodiastolic filling. Toward the end of diastole the atria contract and push
    • the last amount of blood (25% of
    • stroke volume), into ventricles. This active filling phase is called presystole
    • or atrial systole
  46. protodiastolic filling
    protodiastolic filling=first passive filling phase of atria

    • presystole or atrial systole aka “Atrial kick”=Toward the
    • end of diastole the atria contract and push the last amount of blood (25% of stroke volume), into
    • ventricles.
  47. Systole
    • hearts contraction, blood is pumped from ventricles and
    • fills the pulmonary and systemic arteries 1/3 of cycle. Ventricular pressure is
    • finally higher then than in the atria causing mitral and tricuspid valves
    • closure.
  48. All four valves closed for a brief moment
    • All four valves closed for a brief moment until ventricles
    • contract against the closed system causing a surge of pressure opening the
    • aortic valve to the body ejecting blood. Some blood flows backward into the
    • ventricle causing the semilunar valve to close producing the second heart sound
    • S2.
  49. Isometric contraction
    • All four valves closed for a brief moment until ventricles
    • contract against the closed system causing a surge of pressure
  50. S1
    • closure of the AV valve produces the first heart sound S1
    • and signals the beginning of systole. Audible or precordium and loudest at the
    • apex of heart
  51. S2
    • after the ventricle ejects its contents the pressure in the
    • ventricle decreases causing blood to flow backward into the ventricle causing
    • the aortic valve to close producing the second heart sound. S2 signals the end
    • of systole. Audible over precordium and loudest at the base.
  52. S3
    • occurs when the ventricles are resistant to filling with
    • blood during the early rapid filling phase of the ventricles from the
    • protodiastole (atria contracting to push the remaining 25% of stroke volume
    • into ventricle). Occurs immediately after S2 when the AV valve opens and atrial
    • blood first pours into the ventricles.
  53. S4
    • occurs at the end of diastole at presystole when the
    • ventricle is resistant to filling. The atria contract pushing blood into a
    • noncompliant ventricle causing audible vibrations. Occurs just before S1.
  54. Events in right and left sides of heart
    • pressure in right side of heart much lower then the left because the
    • less energy is needed to pump blood to the lungs vs the entire body. Cardiac
    • cycle of right side occurs later then left side due to the route of the
    • myocardial depolarization. This occurrence causes heart sounds S1 and S2 to
    • each have two distinct components. In S1, the mitral component M1 closes just
    • before the tricuspid component T1. With S2, the aortic closure A2 occurs
    • slightly before pulmonic closure P2. These sounds aren’t usually distinguishable
    • and sound like lub dub as in S1 and then S2.
  55. Effects of respiration on Right side of heart
    • = inthrathoracic pressure decreases during inspiration,
    • pushing more blood into the vena cava, increasing venous return to right side
    • of heart, increasing right ventricular stroke volume. The increased stroke
    • volume prolongs right ventricular systole and delays pulmonic valve closure.
  56. Effects of respiration on left side of heart
    • greater amount of blood is sequestered in lungs during
    • inspiration which momentarily decreases the amount of blood returned to the
    • left side of the heart decreasing left ventricular stroke volume. The decreased
    • volume shortens left ventricular systole and allows the aortic valve valve to
    • close a bit earlier. Early closure of the aortic valve before the pulmonic
    • valve allows the two components of S2 “A2 and P2” to be audible called an S2
    • split.
  57. Murmurs
    • occur when the velocity of blood flow increases (flow
    • murmur), viscosity of blood decreases (anemia), and in structural defects in
    • valves or unusual openings occur in the chambers (dilated chamber, wall defect)
  58. Characteristics of heart sounds
    frequency, intensity, duration, timing
  59. SA node
    “pacemaker” of the heart. Intrinsic rythm
  60. Heart’s path of conduction

    • slightly delayed so the atria have time to contract before the ventricles
    • contract-> bundle of his-> right and left bundle branches-> ventricles
  61. P wave
    depolarization of the atrial
  62. PR interval-
    • from beginning of the P wave to the beginning of the QRS complex, (the
    • time necessary for atrial depolarization plus time for the impulse to
    • travelthrough the AV node to the ventricles)
  63. QRS complex
    depolarization of the ventricles
  64. T wave
    repolarization of the ventricles
  65. Hearts pumping ability
    • 4-6 liters of
    • blood per minute through body
  66. Cardiac output
    • the volume of blood in each systole aka “stroke volume”
    • multiplied by the number of beats per minute. CO= SV x R
  67. Heart preload
    • venous return that builds during systole. The length to which
    • the ventricle muscle is stretched at the end of diastole just before
    • contraction. Volume of blood returned to the ventricle ie: “exercise
    • stimulating skeletal muscle to contract and force more blood back to the heart
    • because of systemic pressure”, the muscle bundles are stretched beyond their
    • normal resting state to accommodate. The force of this switch is the preload.
    • Frank –Starling law: the greater the stretch , the stronger the heart’s
    • contraction. The increased contractility results in an increased volume of
    • blood ejected (increased stroke volume)
  68. Heart’s afterload
    • the opposing pressure that the ventricle must generate to
    • open the aortic valve against the higher aortic pressure. The resistance
    • against which the ventricle must pump its blood. Once the ventricle is filled
    • with blood, the ventricular end diastolic pressure is 5 to 10mm hg, whereas
    • that in the aorta is 70-80mm hg. To overcome this difference, the ventricular
    • muscle tenses (isovolumic contraction). After the aortic valve opens, rapid
    • ejection occurs.
  69. Carotid artery
    • = located in the groove between the trachea and the
    • sternomastoid muscle, medial to and along side that muscle. Characteristics of

    • and a downstroke that is more gradual and that has a dicrotic notch caused by
    • closure of the aortic valve.
  70. Jugular veins
    • internal and external jugular veins exist on both sides of the neck.
    • They empty unoxygemnated blood directly into the superior vena cava. The
    • jugular veins give information about the function of the right side of the
    • heart function because there is no valve between the superior vena cava and the
    • right atrium. Reflects filling pressure and volume changes, because volume and
    • pressure increase when the right side of the heart fails to pump efficiently which
    • is visualized by inspecting the jugular veins.

    • tubercle forms around bacilli, scar tissue forms, lesions calcify, extensive erosion as lesion erodes into bronchus
    • initially asymtomatic
    • normal or decreased breath sounds
  289. pulmonary embolism
    undissolved material originating in legs or pelvis detach and travel through venous system returning blood to right heart and lodge to occlude pulmonary vessels
  290. acute respiratory distress syndrome

  293. brachial artery
    • major artery supplying the arm
    • runs in the bicepts-tricepts furrow of the upper arm and surfaces at the antecubical fossa in the elbow medial to the bicepts tendon
    • bifuricates immediately below elbow into the ulnar and radial arteries
  294. ulnar arteries
    run distally and form two arches supplying the hands

    called superficial and deep palmar arches

    pulse located at wrist closest to pinky
  295. radial artery
    pulse located at wrist closest to thumb
  296. femoral artery
    • passes under the inguinal ligament
    • travels down thigh and then is known as popliteal artery
    • pulse located posterior knee medially
  297. popliteal artery
    • located posterior knee medially
    • bifuricates directly below knee
    • turns into anterior tibial artery traveling down to anterior foot to become dorsalis pedis
    • back of leg called posterior tibial artery travels down behind medious malleus and forms plantar arteries
  298. dorsalis pedis artery
    pulse located on top of foot medially, closer to big toe side
  299. posterior tibial artery
    pulse located on interior achilles tendon below joint
  300. veins in the arm
    • each arm has two sets of veins
    • superficial and deep
    • superficial in subcutaneous and responisble for most of the venous return
  301. veins in leg
    • leg contains 3 types of veins
    • 1)deep veins
    • 2)superficial veins
    • 3)perforators
  302. deep veins
    • run alongside the deep arteries and conduct most of venous return for legs
    • these are the femoral and popliteal veins
  303. superficial veins of legs
    these are the great and small saphenous veins
  304. perforator veins of legs
    connective veins that join the superficial and great and small saphenous veins

    contain one way valves that route blood from the superficial into the deep veins
  305. venous flow
    • drain deoxygenated blood and its waste products to the heart
    • low pressure system unlike arteries
    • because veins do not have a pump allowing circulation, they depend on body movement for circulation
  306. venous method of circulation
    • 1)contracting skeletal muscles
    • 2)pressure gradient caused by breathing causing thoracic pressure to increase while abdomainl pressure increases
    • 3)intraluminal valves ensuring one way directional flow
  307. right lymphatic duct
    • empties into right subclavian vein
    • drains right side of head, neck,right arm,right side thorax, right lung and pleura, right side of heart, upper right section of liver
  308. thoracic duct
    • drains everything that the right lymphatic duct doesnt
    • drians into left subclavian vein
  309. functions of lymphatic system
    • 1)conserve fluid and plasma proteins that leak out of capillaries
    • 2)form major part of immune system
    • 3)absorb lipids from intestinal tract
  310. lymph nodes
    • small oval clumps of lymphatic tissue located at intervals along the vessels
    • most nodes located at intervals alongside vessels
    • filter fluid before it is returned to the blood stream
    • expose pathogens to b and t lymphocytes
  311. related organs to lymphatic system
    • spleen-4 functions 1)destroy old blood cells
    • 2)produce antibodies 3)store red blood cells 4)filter microoragnisms from blood
    • tonsils-respond to local inflammation
    • thymus-located insuperior mediastynum, develops t lymphocites in children
    • b lymphocites originate in bone marrow
  312. pulse rating
    • 1+ =weak or thready
    • 3+ - 4+ =full, bounding
  313. pulses paradoxus
    • beats have weaker amplitude with inspiration
    • stronger amplitude with expiration
  314. raynaud's syndrome
    • abrupt, progressive tricolor change in fingers in response to cold, vibration, or stress
    • may expierience cold, numbness, or pain along with pallor or cyanosis
  315. lymphedema
    • high protein swelling of limb
    • most commonly due to breast cancer treatment
    • surgical removal of lymph nodes and vessels with radiation therapy impedes drainage of lymph
  316. arteriosclerosis-ischemic ulcer
    • buildup of fatty plaques on intima
    • hardening and calcification or arterial wall
    • deep muscle pain in calf or foot
    • coolness, pallor, diminished pulse
    • ulcers occur at toes, metatarsal heads, heals, lateral ankle,
    • ulcers characterized by pale ischemic base, well defined edges, and no bleeding
  317. venous (stasis) ulcer
    occurs after acute deep vein thrombosis or chronic incompetant valves in deep veins

    often occurs at medial malleous and characterized by bleeding and uneven edges
  318. deep vein thrombosis
    • deep vein occluded by thrombus, causing inflammation and blocked venous return, cyanosis and edema,
    • 3 factors promoting disorder:stasis, hypercoagulbality, and endothelial dysfunction
    • caused by prolonged bedrest
  319. occlusions
    caused by athersclerosis
  320. aneurysms
    sac formed by dilation of artery wall
