This situation happen because VOLUME OF RBCs in venous blood is high. The volume is increased from arterial blood to venous blood because chloride shift that occurred;relate with increase of carbon dioxide in blood.

Does increasing arterial blood pressure increases blood flow?
YES! Changes in blood volume affect arterial pressure by changing cardiac output. An increase in blood volume increases central venous pressure. This increases right atrial pressure, right ventricular end - diastolic pressure and volume. This increase in ventricular preload increases ventricular stroke volume by the Frank - Starling mechanism. An increase in right ventricular stroke volume increases pulmonary venous blood flow to the left ventricular, thereby increasing left ventricular preload and stroke volume. An increase in stroke volume then increases cardiac output and arterial blood pressure. answered by HappyNess0423
Why haematocrit is more in venous blood?
The changes that take place in the red cell as it traverses the body's capillaries (such as exchange of oxygen and carbon dioxide), lead to a slight increase in red cell osmolarity in the venous blood (ie, there are more molecular particles inside the red cell). This causes the movement of extra water into the red cell (via a process called osmosis), causing them to swell slightly (and increasing the red cell's volume). As haematocrit is equal to the red cell volume divided by the entire blood volume, this leads to a slightly higher haematocrit in venous blood as opposed to arterial blood.
What contains the greater volume of blood arterial or venous system?
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.
What is the main idea of density?
Density is a measure of how much mass is contained in a given volume of a substance. It indicates how closely packed the particles are in a material. Objects with higher density have more mass packed into a smaller volume than objects with lower density.
What increases stroke volume?
increase venous return
What test is used to determine the volume of packed RBCs?
Hematocrit measures the volumeof packed RBCs as a percentage of blood volume.
What factor affecting stroke volume is determine by venous return?
contractility
In which situation would the stroke volume be the greatest?
SV = EDV - ESV Therefore, stroke volume is greatest when venous return is increased. By 1st year paramedic science student.
What does mass and volume mean in teams of density?
The more mass can be packed into a given volume, the greater the density. Alternatively, the less volume into which a given mass is packed, the greater the density.
What might an abnormal increase in venous pressure indicates?
these factors can increase central venous pressure: decreased cardiac output, increased blood volume, venous constriction,forced expiration, muscle contraction
What might an abnormal increase venous pressure indicate?
these factors can increase central venous pressure: decreased cardiac output, increased blood volume, venous constriction,forced expiration, muscle contraction
Is more blood found in the venous system than anywhere else in the cardiovascular system?
Yes, 65-70% of the blood volume is in the venous system.
