Resumo de Recurso

Heart
  1. Four chambers
    1. Right side
      1. Deoxygenated blood
        1. Vena Cava
          1. Right atrium
            1. Tricuspid valves
              1. Right ventricle
                1. Semilunar valves
                  1. Pulmonary artery
      2. Left side
        1. Oxygenated blood
          1. Pulmonary vein
            1. Left atrium
              1. Bicuspid valves
                1. Left ventricle
                  1. Semilunar valves
                    1. Aorta
      3. Features
        1. In ventricles there are TENDINOUS CORDS
          1. Attach to valves and walls to prevent valves inside out - backflow of blood
          2. Ventricular septum
            1. Separates the ventricles
              1. Deoxygenated / oxygenates separate
            2. Valves
              1. Are pocket tissues
                1. Fill with blood and close
            3. Blood pressure
              1. Thin atria walls, blood only goes to ventricles
                1. Left ventricle thickest
                  1. Pump to whole body
                  2. Right ventricle thickish
                    1. Only going to lungs which is close
                      1. Fine capillaries in lungs burst under high pressure
                  3. The cycle
                    1. Sino-atrial nodes
                      1. Atria walls
                        1. atrio ventricular nodes
                          1. purkyne tissue
                            1. Ventricle walls
                    2. Diastole
                      1. Atrial systole
                        1. Ventricular systole
                          1. Ventricles contract - blood forced into arteries.
                          2. Atria contract - blood forced into ventricles, AV valves close
                          3. Relaxed - blood flow into ventricles
