In different parts of the body the blood vessels are of different diameters. The normal diameter of the aorta is around 2 cm and this would be the largest vessel in the human body, while the smallest, a capillary would be between 0.5 to 2.28 mm in diameter.
depends on your definition of "smallest" depends on your definition of "smallest"
Mars is the second smallest with a diameter of 6792km (this is assuming that the dwarf planet Pluto, which has a diameter of 2390km, is not considered; if it is considered, then Mars would be the third smallest). Mercury is the smallest, with a diameter of 4879km.

In the Human Body Sperm cells would be the smallest and Smallest cell is a type of bacteria known as mycoplasma its diameter is 0.0001 mm.
Jupiter is the largest planet and Mercury is the smallest planet in our solar system. Extra-solar radii extremes would be HAT-P-32b as the largest and Kepler-42d as the smallest.
a 25 Gauge needle is capable of drawing blood, but i would go with 21 or 23 for withdrawing lots of blood simply because the 25 gauge could get clogged..
Yes, a 30 gauge needle is larger than a 31 gauge needle. In the gauge system, a higher number indicates a smaller diameter, so a 31 gauge needle is thinner than a 30 gauge needle. Therefore, the 31 gauge needle would be the smaller of the two.
If the needle has the residue of someone who was infected with HIV/AIDS's blood on it, and the needle goes under your skin and into your blood, then yes. However, unless you're punctured by the needle, you can't be infected with HIV.
Mars, the second-smallest planet, has a diameter of just 6,788 km and the smallest planet, Mercury, has a diameter of 4,880 km, less than 2,000 km smaller than Mars. So it would take 1.34 mercury's to equal the diameter of Mars.
A 25-gauge needle is smaller in diameter than a 23-gauge needle. The larger the gauge number, the thinner the needle, so a 25-gauge needle has a smaller lumen compared to a 23-gauge needle. This means that for tasks requiring finer needles, such as pediatric or cosmetic procedures, a 25-gauge needle would be preferred.
