The right side of the heart collects de-oxygenated blood from all parts of the body, and directs it to the lungs for the dumping of carbon dioxide for oxygenation. The left side of the heart collects oxygenated blood from the lungs and directs it for use by the rest of the body.
The function of the vena cava is to return blood back to the heart.
The inferior vena cava brings blood from the lower parts of the body to the heart. The blood is deoxygenated.
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.
Heart has two sides (4chambers) separated by a septum.One side it collects the impure blood ie from all the parts of our body and pumps it to lungs. At lungs through alveoli the co2 diffuses out and oxygen enters the blood. this pure blood (oxygenated blood) enters the other side of heart from where it is pumped to all body parts AND cycle continues.
The vena cava (both) are very large veins. All veins carry blood back to the heart. In the case of the vena cava, this is blood from the upper body (superior vena cava) and from the lower body (inferior vena cava).
Simple answer: Veins Complex answer: a series of blood vessels (excluding arteries) carries deoxygenated blood from the body to the heart. Where the blood is then passed through an oxygenating process with the lungs. Another answer: pressure caused by the beating of the 4 chamber heart.
Away from the heart and towards the other part of the body.... Blood contains haemoglobin which carries oxygen from the heart to the other parts of the body. It also collects Carbon-di-Oxide from the cells all over the body and transmits it to the heart. The artery does the first job and the veins does the latter.........

Veins - Carry Blood Towards The Heart;))
They bring de-oxygenated blood from other parts of the body to the heart, where it is pumped to the lungs to be oxygenated and sent out again through the aorta of the heart to the arteries.
The haert pumps blood from the arteries and to the other parts of the body while the veins take blood into the heart.
