- - - - Small veins;connect capillaries and veins
  - - - small arteries found between arteries and capillaries
  - - - Middle, smooth muscle layer
    - - Outermost, fibrous C.T
    - - Endothelium (inner layer of blood vessels)
- - - - Atria
        
        Receiving chambers
        
        Right atrium
        
        Receive blood from the rest of body
        
        Left atrium
        
        Receives blood from lungs
      - Ventricles
        
        Discharging chambers
        
        Left ventricle
        
        Discharges blood to the rest of body
        
        Right ventricle
        
        Discharges blood to lungs
    - - Atrioventricular valves (AV valves)
        
        Between atria and ventricles
      - Semilunar valves
        
        Pulmonary semilunar valve
        
        Between right ventricle and pulmonary trunk
        
        Aortic semilunar valve
        
        Between left ventricle and Aorta
  - - - Middle, thick muscle layer
    - - Inner lining
    - - Outer C.T layer
  - - - Flow of blood from rest of the body to the heart
    - - Flow of blood to myocardium of heart
    - - Flow of blood to and from lungs to heart
- - - - Common Carotid Artery
      - Internal Carotid Arteries
      - Brachiocephalic Artery (Trunk)
      - External Carotid Arteries
      - Aortic Arch
      - Subclavian Arteries
    - - Abdominal Aorta
      - Common Hepatic Artery
        
        Brings blood to the liver
      - Celiac Artery
      - Splenic Artery
        
        Brings blood to the spleen
      - Renal Artery
        
        Blood to the kidneys
      - Ovarian Artery
        
        Blood to the ovary
      - Testicular Artery
        
        Blood to the testicles
  - - - Splenic Vein
        
        Brings blood away from spleen
      - Renal Vein
        
        Brings blood away from kidneys
      - Hepatic Portal Vein
        
        Brings blood away from liver
      - Ovarian Vein
        
        Brings blood away from ovary
      - Left Gastric Vein

      - Brachiocephalic Vein
      - Ulnar Vein
      - Subclavian Veins
      - Basilic Vein
- - - - Blood pressure builds before ventricle contracts, pushing out blood.
    - - Blood flows into ventricles
    - - Atria finish re-filling, ventricular pressure is low.
  - - - Parasympathetic NS causes high blood pressure
    - - Internal control of heart rate
      - Sa node =AV node=Av bundle=bundle branches = purkinde fibers=ventricular wall
        
        Av node
        
        At junction between atria and ventricles
        
        SA node
        
        pacemaker
        
        Av bundle
        
        Bundle of HIS
        
        Bundle branches
        
        Located at the interventricular septum
        
        Purkinje fibers
        
        Specialized myocardial muscel fibers that conduct electrict impulses; spread within muscles of ventricular wall
    - - Sympathetic NS Ex. exercise/hormones causes low blood pressure
    - - Amount of blood pumped by each side of heart in 1 min
      - CO=(heart rate [HR]x(stroke volume[SV]
