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.

Why arterial blood is more alkaline than venous blood?
pulmonary arterial blood as it has moce CO2 than venous
What are causes of dark venous blood?
it has more oxygen than arterial blood
How do haematocrit levels change during and after exercise?
Haematocrit levels usually increase during and after exercise due to higher blood pressures forcing fluid out of cells therefore reducing plasma volume and producing a false haematocrit reading.
How does arterial blood and venous blood differ with regard to their oxygen and carbon dioxide content?
Arterial blood have more Oxygen and venous blood have more CO2 except the pulmonary vien which carry oxygenated blood to the heart for pumping to arteries.
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.
What function do venous vessels serve?
to hold more blood when volume increases
What is The slightly lower pH of venous blood compared to arterial blood is caused by?
The influx of carbon dioxide in venous blood.
What does the venous system do?
The venous system is responsible for returning deoxygenated blood from the tissues back to the heart. It transports this blood through a network of veins, which have valves to prevent the backflow of blood. The venous system also plays a role in regulating blood volume and pressure in the body.
What is the color of venous blood?
interesting fact when blood is in your veins it is blue but when you get a shot oxygen hit you blood and it turns red.
What contains venous blood?
an octopus
Does everyone have venous blood?
Yes. If they are alive, they will have venous blood, which carries blood to the heart.
Why packed cells volume higher in venous than arterial?
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.
