What is superior vena cava syndrome?
Hello, I see you are asking "What is superior vena cava syndrome?" Superior vena cava syndrome (SVCS) is a group of problems caused when blood flow through the superior vena cava (SVC) is slowed down. The SVC is a large vein that drains blood away from the head, neck, arms, and upper chest and into the heart. SVCS is most often seen in people who have cancer.

Would an obstruction in the superior vena cava decrease the flow of blood from the head and neck to the heart?
yes
What direction does the blood flow in the heart?
there are two main veins that makes the blood flow toward the heart which are the superior vena cava and inferior vena cava.
What do the pulmonary veins and the superior and inferior vena cava have in common?
They all are veins and the blood in them all flow toward the heart
What is faster blood flow in the center of a large vessel or blood flow along the walls of a blood vessel?
Blood flow in the center of a large vessel is faster because the walls of the blood vessel may have a buildup of cholesterol on them.
Are the inferior and superior vena cava systemic veins?
The inferior vena cava is a large vein. The two common iliac veins join to make the inferior vena cava, which receives blood from the lower body and empties it into the right atrium of the heart.
Through which parts of the heart does oxygen-poor flow?
the inferior and superior vena cava
Where is the inferior vena cava located?
The vena cava are two sets of veins: the superior vena cava, and the inferior vena cava. The inferior vena cava is the longest vein in the body. The superior vena cava mainly (by volume) brings deoxygenated blood from regions of the body above/at the level of the heart & the arms. The azygous vein anastomoses with the superior vena cava, and thus the superior vena cava receives blood from both sides of the posterior wall of the thorax, via the azygous vein and hemiazygous vein. In some individuals anastomoses may occur between the azygous & hemiazyous vein with the right & left renal veins, respectively, and/or the inferor vena cava. Therefore blood returning to the heart via the abdomen or kidneys may also pass through the superior vana cava to the heart. The inferor vena cava returns blood, mainly from the level below the diaphragm down to the feet, to the heart.
Does the systematic circulation flow to the left atrium?
Yes, blood from both the inferior and the superior vena cava flow into the right atrium. Blood from the pulmonary veins coming from the lungs flow into the left atrium.
How the blood flowing to the heart?
Blood courses along veins back towards the heart. The veins have one way valves to prevent back flow. Venous blood from below the heart drains into the inferior vena cava. Venous blood from above the heart drains into the superior vena cava. These empty into the right atrium.
What chamber receives the blood from all parts of the body except the lungs?
Blood from the superior vena cava and inferior vena cava meet to flow into the right atrium, then to the right ventricle, in order to go into the lungs and refresh the oxygen in the blood .
What happens with the blood in the lymphatic system?
The fluid in the lymphatic system is not blood, it resembles plasma but contains some different things. This fluid is carried via the lymph nodes back to joind the blood flow at the superior vena cava.
