CARDIOVASCULAR (ANATOMY OF THE HEART (MUSCLE/TENDON (CHORDAE TENDONEAE…

- - - - A cavity in the heart that lies to the right of the right atrium and above the left ventricle
    - - A cavity in the heart that lies to the right of the right ventricle and underneath the left atrium
    - - Cavity that is above the right ventricle,blood from superior/inferior vena cava dump here
    - - A cavity in the heart that lies below the right atrium
  - - - prevent back flow of blood/left side
    - - prevent back flow/ right side
  - - - this vessel returns blood directly to the right atrium from the muscular wall of the heart
    - - Carry blood back into the heart from the lungs
    - - just below the right atrium and follows horizontally along the heart
    - - outside the heart that runs vertically
  - - - Small tendons on the interior of the heart in the region of the right ventricle
    - - lies on the inside of the right atrium, t is an embryonic remnant of the foramen ovale, which normally closes shortly after birth.
    - - makes the heart pump, muscle surrounding the inner aspects of the heart
    - - muscle that runs along the inside of the left atrium, regulates the action of valves
    - - the blood that enters the right side of the heart enters here
    - - a thick wall that separates the left and right atriums
    - - Large vein that lies on top of the right atrium and left to the aorta
    - - On the bottom of the right atrium, adjacent to the entrance of the superior vena cava, cells here initiate the heartbeat and is called as the pacemaker of the heart.
    - - At the floor of the right atrium, between opening for the coronary sinus
    - - specialized muscle fibers regulating the heartbeat by conducting impulses from the right atrium to the ventricles
    - - extends from AV node into/through the septum, divides into the left/right bundles
    - - extend from left/right bundles, begin at the apex of heart and continue through the walls of the ventricles
- - - - Atrial Depolarization
        
        Starts in the SA node, lasts between 0.08 to 0.1 seconds
    - - Ventricular Depolarization
        
        lasts between 0.06 to 0.1 seconds
    - - ventricular Repolarization
