Cardiovascular System (Clinical Terms (Cardiac Output (Volume of blood…

- - - - Made of epithelium
    - - Composed of dense irregular CT
    - - Made of cardiac muscle
    - - Space between the two pericardium
    - - Made of Simple squamous epithelium and areolar CT
    - - The outer layer of the pericardium that is made of fibrous tissue
  - - - Groove on the anterior part of the heart where the Anterior Interventricular Artery
        
        Anterior Interventricular Sulcus
      - Left Coronary Sulcus
        
        Groove where the Left Coronary Artery lies
      - Right Coronary Sinus
        
        Groove where the Right Coronary Arteries
    - - Right Coronary Artery
        
        Supplies blood to right side of heart
      - Left Coronary Artery
        
        Supplies blood to the left side of heart
      - Circumflex artery
        
        Supplies blood to left atrium
      - Anterior Interventricular Artery
        
        Supplie s blood to left ventricle
    - - Fibrous band, between Aorta and Left Pulmonary Artery
    - - Helps to increase the capacity of the Atrium
    - - The tip of the heart
    - - The dorsal part of the heart that is superior to the apex
    - - Small veins that come together at the heart to form a sinus
  - - - Interatrial Septum
        
        Separates the atria, it is a wall of tissues
      - Interventricular Septum
        
        Separates the two ventricles
    - - When contracted opens the valves leading to the ventricles, allowing blood to enter
    - - Depression in the right atrium made of thin fibrous sheet
    - - Pulmonary valves
        
        Prevents back flow of deoxygenated blood into the right ventricle
      - Aortic Valve
        
        Once contracted allows blood to exit the left ventricle into the aorta
      - Mitral Valve
        
        When left atrium fills with blood it opens to allow blood into left ventricle
      - Tricuspid Valve
        
        Prevents back flow of blood from weight ventricle into right atrium
    - - Receives blood returning to the heart
    - - Left ventricle
        
        Receives oxygenated blood from the left atrium through the mitral valve
      - Right Ventricle
        
        Receive deoxygenated blood from the right atrium through the tricuspid valve
    - - Holds the atrioventricular valves in place while heart is contracting
  - - - Beginning of the aortic arch
    - - Carries oxygenated blood from the lung back to the left atrium
    - - Branches into the right and left arteries
    - - Carries deoxygenated blood from the lower half of the body to the right atrium
    - - Returns deoxygenated blood from the systemic circulation to the right atrium
    - - Coronary arteries branch off the ascending aorta to supple heart with blood
    - - Transports oxygen depleted blood away from heart to the lungs
    - - Where the Aorta bends
- - - - After depolorization
- - - - ST Segment : ventricular depolarization
        
        P Wave: Atrial depolarization
  - - - Heart is relaxed: AV valve opens to allow blood into the ventricle
- - - - SNS: When the heart must pump blood at high volume throughout the body (EX: Exercise)
      - PNS: This is used for more restful situations (Ex: Sleep)
  - - - AV Bundle
        
        Right and left bundles
        
        Purkinje fibers
