There is some of both. If you think about it, that has to be true. It flows in, it flows out.
Venous blood from body tissues is deoxygenated. It flows into the heart at the right atrium, through the tricuspid valve, and into the right atrium. Then it gets pumped to the lungs through the pulmonary semilunar valve. It becomes oxygenated in the lungs, then goes to the left atrium of the heart where it passes through the bicuspid valve and then is pumped through the Aortic semilunar valve where it becomes arterial blood.
From the capillaries of the kidney, deoxygenated blood flows through the renal vein. The renal vein empties directly into the inferior vena cava which carries the blood back to the heart.
In a portal system, blood flows from a capillary bed through veins to another capillary bed. It differs from normal venous return because it is not taken straight to the heart.
The River Thames flows through southeastern Great Britain to the English Channel.
Channel flow is how much water flows through a channel.
Channel (Valley)
Connective tissue flows through the heart and blood vessels.
The average velocity of the blood as it flows through a capillary is 0.00047 m/s.
The Seine flows through Paris and eventually empties into the English Channel. The channel separates Britain from France.
the three pathways through wich blood flows are the arteries,veins,and capillaries
The Seine River flows between Paris and the English Channel. It flows from Paris through several French cities that include Normandy before entering the English Channel.
