Veins, the largest vein cavae, are even largest in Diametre than Aorta arteri
The aorta is the largest blood vessel in the human body.It is left of the heart.
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.

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. :)
Resistance is determined by three properties: the lengthand cross-sectional area of a material, and its resistivity. Since resistivity is affected by temperature, you could say that temperature indirectly affects resistance.

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.

advantage of cross sectional study?
slowest in the capillaries because the total cross-sectional area is the greatest
You cannot create a cross sectional area of a rectangle. You can only create cross sectional areas for triangular shapes.
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.
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.
