Which veins are directly connected to the atriumright ventricles?

Answer 1

There are two vessels Superior vena cava and Inferior vena cava. This is for your pulmonary circuit.

*The coronary sinus drains deoxygenated blood from the myocardium, from there it empties into the right atrium. The anterior cardiac veins drain the right and left ventricles and open directly into the right atrium. There are four blood vessels that empty into the right atrium:

1-inferior vena cava

2-superior vena cava

3-coronary sinus

4-anterior cardiac veins

Answer 2

Blood received in the right atrium is pumped out of the heart by the right ventricle. This is the half which sends deoxygenated blood to the lungs to be oxygenated again. The left half of the heart receives oxygenated blood from the lungs and then pumps it around the body.

Since the blood entering the right atrium is therefore 'used blood' it must have come from the body, and this large vein is called the Vena Cava. Blood from the upper body enters via the Anterior or Superior Vena Cava, while blood from the lower half of the body enters via the Posterior or Inferior Vena Cava.

Answer 3

The Coronary sinus located on the posterior surface of the heart empties oxygen poor blood into the right atrium

Answer 4

The Vena Cava, the main vein which carries deoxygenated blood to the haert from the systemic circulation

Answer 5

Superior Vena Cava

Answer 6

The superior and inferior vena cava.

Answer 7

Coronary sinus
