60 yr old woman w/ history of obesity and DMII and has experience a heart…

- - - - Right Atrium
        
        Receives blood returning from systematic circuit
      - Right Ventricle
        
        Pumps blood into the pulmonary circuit
    - - Left Atrium
        
        Receiving blood from returning from pulmonary circuit
      - Left Ventricle
        
        Pumps blood into the systematic circuit
    - - Right Atrium
      - Left Atrium
    - - Right Ventricle
      - Left Ventricle
    - - In mediastinum
        
        Medial cavity of the thorax
      - Second and fifth rib intercostal space
      - Base
        
        Posterior surface
        
        Leans toward right shoulder
      - Apex
        
        Points toward the hip
      - Apical Impulse
        
        Palpated between 5th and 6th ribs just below left nipple
    - - Pericardium
        
        doubled-wall sac that surrounds the heart made of 2 layers
        
        superficial-fibrous pericardium
        
        Protect and anchor heart to surrounding structures and prevent over filling
        
        deep two-layered serous pericardium
        
        Parietal layer
        
        Lines internal surface of fibrous pericardium
        
        Visceral layer
        
        (epicardium) on external surface of the heart
    - - Myocardium
        
        Spiral bundles of contractile cardiac muscle cells
      - Endocardium
        
        inner most layer, endothelial lining with blood vessels
      - Epicardium
        
        Visceral pericardum
  - - - Atrium contracts, blood flows from right atrium to right ventricle through open tricuspid valve.
        
        Ventricle is full, tricuspid valve shuts. prevents blood from flowing back into atria while contraction is occuring
        
        Ventricle contracts, blood leaves heart through the pulmonic valve, into the pulmonary artery and to lungs where its oxygenated.
  - - - Aortic valve
        
        guard large arteries and prevent back flow
      - Mitral valve
        
        Left atrioventricular valve
      - Pulmonary valve
        
        Pertaining to lungs, guard large arteries and prevent back flow
      - tricuspid valve
    - - Muscles located in the ventricles of the heart
        
        Attach to the cusps of the atrioventricular valves( mitral and tricuspid)
        
        Chordae tendinaee
  - - - pace the heart
    - - non contractile cells specialized to initiate and distribute impulses through the heart
      - Sinoatrial node
        
        Atrioventricular node
        
        specialized mass of conducting cells located at the atrioventricular junction in the heart
        
        Atrioventricular bundle
        
        bundle of specialized fibers that conduct impulses from the AV node to the right and left ventricles
        
        Right and left bundle branches
        
        Subendocardial conducting network
        
        Modified ventricular muscle fibers of the conduction system of the heart.
        
        specialized myocardial cells in the wall of the right atrium; pacemaker of the heart.
  - - - increase of heart rate for need of more oxygen and decrease of rate for less oxygen
    - - responds to the quick act of a drop in pressure
    - - Thyroid glang
      - Pituitary glad
        
        influences heart rate
    - - Omega 3
      - exercise
      - Cholesterol and blood pressure regulation
      - stop smoking
      - Blood sugar control
      - Fiber control
