Aorta has largest diameter but least cross sectional area (KAPLAN PHYSIOLOGY),

capillaries has largest total cross sectional area (KAPLAN PHYSIOLOGY).

Capillaries are mere millimeters wide. They are the smallest blood vessels in the body.

The aorta is the largest. The superior/inferior vena cava and the pulmonary artery and vein are also large.

What is the relationship between cross sectional area of blood vessel and velocity of blood flow in that vessel?

Proceeding downstream from the aorta, branching of arterial vessels increases total cross-sectional area and thus results in diminished velocity of blood flow from the aorta to the capillaries. Velocity increases from the capillaries to the large veins with the confluence of vessels and the resulting decrease in total cross-sectional area. :)


What three variables affect peripheral resistance to blood flow?

The three variables that affect peripheral resistance to blood flow are the radius of the blood vessels (vasoconstriction or vasodilation), the length of the blood vessels, and the viscosity of the blood. Changes in these variables can impact the resistance to blood flow in the peripheral circulation.

What are blood vessles called?

The tiny blood vessel is called as capillary. The diameter of the capillary is about 8 micrometer. They are present through out your body. They are present in your body in very large number. Together the cross sectional area of them all is about 2500 square cm.

How does the law of continuity relate to the velocity of blood flow?

If a pipe's diameter changes over its length, a fluid flows through narrower segments of the pipe faster than it flows through the wider segments. Since the volume of flow per second must be constant through the entire pipe, the fluid must flow faster as the cross-sectional area of the pipe narrows (think of the velocity of water squirted by a hose with and without a nozzle).Based on the law of continuity, you might think that blood should travel faster through capillaries than through arteries, because the diameter of capillaries is very small. However, it is the total cross-sectional area of the capillaries that determines flow rate. Each artery conveys blood to such and enormous number of capillaries that the total cross-sectional area is much greater in capillary beds than in any other part of the circulatory system.For this reason, the blood slows substantially as it enters the arterioles from arteries, and slows further in the capillary beds. As blood leaves the capillaries and enters the venules and veins, it speeds up again as a result of the reduction in total cross-sectional area.


How do you do a cross sectional area of a rectangle?

You cannot create a cross sectional area of a rectangle. You can only create cross sectional areas for triangular shapes.


Can veins store blood?

Cross sectional area of veins is four times that of arteries This large cross sectional area plus large degree of compliance (yielding to pressure) implies that large amounts of blood can be stored in the veins with only minimal increase in pressure.


What is the smallest blood vessel in the body?

Actually the smallest blood vessels are capillaries. These blood vessels are only about 1 cell thick and is where the gas and nutrient exchanges occur. It is also the cross-bridge between vein and arteries.


Can veins store excess blood?

Cross sectional area of veins is four times that of arteries This large cross sectional area plus large degree of compliance (yielding to pressure) implies that large amounts of blood can be stored in the veins with only minimal increase in pressure.


How does cross sectional area affect resistance?

the larger the cross sectional area, the smaller the resistance
