Cardiovascular system:, Blood, Blood pressure - Coggle Diagram

- - - - pericardial: space between visceral and parietal
      - visceral: inner layer of serous membrane
      - parietal: deep to fibrous
      - Fibrous: tough outer
      - wall of heart
        
        endocardium
        
        Epicardium (visceral )
        
        myocardium
    - - R atrium: Receives blood from systemic circuit
      - R ventricle: receives blood from R atrium
      - L atrium: Receives blood from pulmonary veins
      - L ventricle: receives blood from the left atrium
      - aurticles: flaps from atria
      - Septums and Valves:
        
        Interatrial septum:
        
        interventricular septum
        
        superior and inferior venae cavae
        
        tricuspid valve
        
        pulmonary semiunar valve
        
        mitral bicuspid valve
        
        aortic semiunar valve
        
        chordea tendineae
        
        4 pulmonary veins
  - - - R and L coronary artery
      - Tunics*
        
        media: contractions causes vasoconstriction
        
        externa
        
        interna
      - 3 major branches of aortic arc:
        
        left common carotid artery
        
        left subclavian artery
        
        brachiocephalic trunk
    - - Continuous: muscle and nervous tissues
      - fenestrated: endocrine glands and small intestine lining
      - sinusoidal: spleen and bone marrow
      - Made of simple squamous, thin, uses hydrostati pressure
- - - - Ventricular systole
      - isovolumetric relaxtion
      - Ventricular filling
      - ventricular filling
      - Regulations: parasympathetic and sympathetic impulses, baraoreceptor reflexes
      - clinical
        
        Tachycardia: fast heatbeat
        
        bradycardia slow heartbeat
        
        arrhythmias: altered heart rhythms
        
        flutter: rapid contractions
        
        premature beat: beat before expected
        
        ectopic pacemaker: Damage to SA node
        
        artificial pacemaker: device
        
        fibrillation
      - cardiac output = heart rate x stroke volume
