After it makes its circuit throughout the body, blood must return to the heart. the veins carry the blood back toward the heart via the superior and inferior vena cava. The vena cava empty into the right atrium of the heart to begin the cycle again.
Low oxygen blood flows into the Right Atrium, through the Tricuspid Valve into the Right Ventricle, and then up the pulmonary artery to the lungs for reoxygenation.
The right atrium
renal vein
our total blood volume is unevenly distributed amongst the arteries, veins and capillaries. The heart, arteries , pulmonary and systemic circuits contain about 1.5 liters of whole blood. The venous system contains 3.5 liters, which is circulating within the liveer, bone marrow and skin.
The venous duct connects the umbilical arteries to the liver.
Syndromes related to venous insufficiency are caused by valve incompetence. Venous insufficiency is a chronic (long term) condition
dural venous sinuses
renal vein
Venous reserve is available to maintain tissue oxygenation if either systemic oxygen demand increases or arterial content falls.
Arcuate Vein
The names of the two sides of the heart are the right heart and the left heart. The right heart is a low pressures pump that receives venous blood from the systemic circulation and pumps it to the lungs. The left heart is a high pressure pump which receives blood from the pulmonary veins and pumps it to the rest of the body via the aorta.
The answer is Protosystemis ShuntOrdinarily the blood coming away from the digestive tract is kept in a venous network (the "portal" system) separated from from blood that is returning directly to the heart via the vena cava (the "systemic" flow). This portal blood must first be cleaned and detoxified by the liver before merging with systemic venous blood.If there is abnormal flow which permits the "dirty" digestive blood tobypass the liver, it is called a Porto-Systemic "shunt".
A fistula is an abnormal pathway between 2 anatomic spaces or a pathway that leads from an internal cavity or organ to the surface of the body. A sinus tract is an abnormal channel that originates or ends in one opening.
Venous return (VR) is the flow of blood back to the heart. Under steady-state conditions, venous return must equal cardiac output (CO) when averaged over time because the cardiovascular system is essentially a closed loop.if systemic venous return is suddenly decreased, right ventricular preload decreases leading to an decrease in stroke volume and pulmonary blood flow.Decreased pulmonary venous return to the left atrium leads to decreased filling (preload) of the left ventricle, which in turn decreases left ventricular stroke volume by the Frank-Starling mechanism.In this way, a decrease in venous return to the heart leads to an equivalent decrease in cardiac output to the systemic circulation.
Venous return (VR) is the flow of blood back to the heart. Under steady-state conditions, venous return must equal cardiac output (CO) when averaged over time because the cardiovascular system is essentially a closed loop. Otherwise, blood would accumulate in either the systemic or pulmonary circulations.
Venous ulcer are caused by venous insufficiency (improper functioning of venous valves).
Arterial blood in the systemic circulation is higher in oxygen and lower in carbon dioxide than venous blood. In the pulmonary circulation, arterial blood is lower in oxygen and higher in carbon dioxide than venous blood.

No. Venous is simply a modifier to the brand name Doppler.
