Not sure what you mean by "anterior and posterior", but veins return blood to the heart. I believe you are mistaken. the Superior and Inferior vena cava return blood to the heard.

What is the orientation of the heart?
intrathoracic, in mediastinum, anterior to esophagus and posterior to the diaphragm
What chamber of the heart lies most anterior?
Right Ventricle. The most posterior is the Left Atrium
What is anterior to the heart?
The sternum is anterior to the heart.
What circulatory system supplies the heart with blood?
Through it's own network of arteries in the heart itself. These are the arteries that are disrupted during a heart attack, and they are also bypassed during a bypass surgery with veins from the legs.
What are the major branches of the coronary arteries and heart region served?
The left coronary artery branches into the anterior interventricular artery which supplies blood to the interventricular septum and anterior walls of both ventricles and the circumflex artery which supplies the left atrium and the posterior walls of the left ventricle. The right coronary artery branches into the right marginal artery which serves the myocardium of the lateral right side of the heart and the posterior interventricular artery which supplies the posterior ventricular walls.Reference: Marieb, Elain N. (2013).Human Anatomy & Physiology. 9th ed. United States: Pearsons Education, Inc.. p669-670.
Blood returns to the heart via the anterior and posterior?
pulmonary veins
Which plane divides the heart into anterior and posterior portions?
The frontal (also known as coronal) seperates the heart into anterior and posterior portions.
Is the spinal cord posterior to the lungs?
No, the heart is anterior to the spine. Posterior means "behind" therefore the spine is posterior to the heart.
The heart is cut so that the anterior and posterior parts results the section is called?
A transverse section of the heart that separates the anterior and posterior parts is known as a coronal section. This section allows for the visualization of both the front (anterior) and back (posterior) portions of the heart, providing a comprehensive understanding of its structure.
What are the three structures found in the heart?
The heart has three surfaces: anterior, inferior and posterior. The anterior, sternocostal surface, the inferior or diaphragmatic surface and the base of the heart, the posterior surface.
What is the orientation of the heart?
intrathoracic, in mediastinum, anterior to esophagus and posterior to the diaphragm
What are the functions of the posterior and anterior vena cavae and where are they located?
they are responsible for bringing deoxygenated blood back to the heart (left side) to be distributed to the rest of the of the body
What structure is anterior to the heart?
Inferior to the heart: Stomach Superior to the heart: Brain Anterior to the heart: Rib cage Posterior to the heart: Spine Latereral to the heart: Lungs
Is the heart anterior or lateral to the sternum?
The heat is posterior to the sternum, not anterior. It is a midline structure, like the sternum, so it is not lateral to the sternum.
What chamber of the heart lies most anterior?
Right Ventricle. The most posterior is the Left Atrium
Where is the base of the heart located?
The upper most anterior / inferior connecting part of the Heart to the Arteries.
What contributes to the formation of the popliteal vein?
The popliteal vein carries blood from the knee to the thigh and calf muscles and ultimately to the heart. The vein is formed from the merging of the two posterior tibial veins and ends as it merges in to the femoral vein.
