Question

Why should we donate blood through veins and not arteries?

Answer 1

Answer:

1) As they carry the blood.

2)Venous pressure is also lower than arterial pressure, so there is less of a chance of blood seeping back out through the puncture point before it heals. Because of their thinner walls, veins tend to be larger than the corresponding artery in the area, so they hold more blood, making collection easier and faster.

Answer 2

because veins connected to blood vessels and arteries connected to heart
