Coronary Sinus does not transport blood directly into the right atrium.

Step-by-step explanation:

  • "Coronary sinus" is a group of veins joined collectively to form a big vessel that accepts blood from the myocardium.
  • It is positioned along the heart's posterior surface between the left ventricle and left atrium.
  • The outline of the vein is larger than normal and is huge enough to enable blood to be collected by most veins that enter the heart.
  • The coronary sinus receives the maximum of the cardiac venous blood.
  • It releases blood with less oxygen to the right atrium, like how "superior and inferior venae cavae" does.
  • It is found in "mammals", including humans.
