We just learned about the Axillary, Cephalic and Brachial veins in the upper arm.
There is a very important vein in the elbow area called the median cubital vein.
This vein brings blood through the elbow area and back up the arm toward the heart.
When doctors have to put medicine into your blood, or if they have to take a sample of your blood to test for something, they usually poke a needle into your median cubital vein.
This is because it is a very large vein, and very close to the top of your skin so it is easy to see and find.
