The right atrium receives venous blood from the systemic circuit through the superior and inferior vena cava.
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.

What receives all the venous blood from kidney?
renal vein
The name of the venous sinuses that drains the aqueous humor is?
The venous sinuses that drain the aqueous humor from the eye are called the Schlemm's canal or the canal of Schlemm. This structure is located in the angle of the anterior chamber of the eye where the cornea and iris meet.
What is the physiology of venous insufficiency?
Syndromes related to venous insufficiency are caused by valve incompetence. Venous insufficiency is a chronic (long term) condition
What is central venous pressure?
Normal central venous pressure is in the range of 2-8 cmH2O.
What contains the greater volume of blood arterial or venous system?
The venous system contains a greater volume of blood compared to the arterial system. This is because veins act as a reservoir where blood is stored before returning to the heart, while arteries carry blood away from the heart to various parts of the body.
What receives all the venous blood from kidney?
renal vein
What receives venous blood from the cortical radiate vein?
Arcuate Vein
What are the names of the two main sections of the heart?
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.
What is the medical term meaning abnormal blood vessel creating abnormal blood flow around the liver?
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".
What is the difference between a sinus and a vein?
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.
What happens when there is a reduction to the blood returning to the heart does it increase?
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.
The name of the venous sinuses that drains the aqueous humor is?
The venous sinuses that drain the aqueous humor from the eye are called the Schlemm's canal or the canal of Schlemm. This structure is located in the angle of the anterior chamber of the eye where the cornea and iris meet.
What improves venous return to the heart during strenuous exercise?
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.
At sea level what is the normal partial pressure of oxygen in the systemic veins?
The normal partial pressure of oxygen in the systemic veins at sea level is around 40 mmHg. This value indicates the pressure exerted by oxygen molecules in the blood and corresponds to the oxygen content in the venous blood returning to the heart.
What causes venous ulcer?
Venous ulcer are caused by venous insufficiency (improper functioning of venous valves).
Why is there a venous reserve of oxygen in the blood?
The venous reserve of oxygen in the blood allows for a safety margin and helps maintain tissue oxygenation during periods of increased oxygen demand or decreased oxygen delivery. It ensures that tissues receive a continuous supply of oxygen even when there are fluctuations in oxygen levels in the body.
How is blood in arteries different from blood in veins?
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.
