veins....
Since you use the word small, these vessels are called venoules.
The three types of blood vessels are:1. Arteries2. Veins3. Capillaries (small blood vessels in the tissues)They are:(1) Arteries - These are the blood vessels that carry blood away from the heart. They generally carry oxygenated blood except the pulmonary artery.(2) Veins - These are the blood vessels that carry blood towards the heart. They generally carry de oxygenated blood except the pulmonary vein.(3) Capillaries - They generally form a capillary network through which substances are exchanged between the blood and tissues. Capillaries carry blood from arterioles (branches of artery) to venoules (branches of vein).
Let's start from the heart. The blood drop goes out through the aorta, to other, smaller arteries. Arterioles. Capillaries. Venoules. Veins. Back to the heart (right atrium). From the right atrium, it goes to the right ventricle, to the pulmonary artery, to the lungs, into the pulmonary veins, which bring it to the left atrium of the heart. It then moves to the left ventricle, and out again through the aorta. Note that the drop of blood you started out with would not be the same drop you ended up with.
