Heart (Background of Heart (Anatomy of Heart and all relevant structures…

- - - - Veins-transport blood toward the heart
      - Capillaries- where blood/O2 exchange happens in organs and all systemic cells.
      - Arteries-transfer blood away from the heart
    - - Left ventricle-larger chamber that receives blood from left atrium and pumps blood to the body
    - - Right atrium- smaller chamber that receives O2 poor blood from the body to the right ventricle
      - Superior Vena Cava- drains blood from the head,neck,upper limbs and superior region of the trunk to the heart. (Right atrium)
      - Inferior Vena Cava- drains blood from lower limbs and inferior regions of the trunk to the heart (right atrium)
    - - Right AV valve( Tricuspid valve)- between the right atrium and right ventricle
      - Left AV valve (bicuspid or the mitral valve)- located between the left atrium and the left ventricle
    - - Pulmonary semilunar valve- between the RV and pulmonary trunk
      - Aortic semilunar valve- between the left ventricle and the aorta
  - - - Right Ventricle
        
        Pulmonary Trunk
        
        Pulmonary SL valve
      - Tricuspid AV valve
  - - - Afterload- the force or load against which the heart has to contract to eject the blood
        
        Peripheral resistance- the resistance that must be overcome to push blood through the circulatory system and create flow
- - - - Aorta
