capillaries? i'm assuming you're talking about in the body?
The blood vessel that only allows one corpuscle to go through at a time is called a capillary.
Capillary: these tiny blood vessels facilitate the exchange of nutrients, oxygen, and waste products between the blood and tissues. Their small size allows for efficient nutrient and gas exchange due to their proximity to body cells.
An arteriole is a small blood vessel that carries oxygenated blood away from the heart and towards the tissues of the body. Arterioles regulate blood flow and blood pressure by constricting or dilating. They are important in controlling blood flow to specific areas based on the body's needs.
Capillaries are the smallest blood vessels in the body that connect arteries and veins. They are very narrow tubes that allow for the exchange of gases, nutrients, and waste products between blood and body tissues.
Red blood cells carry oxygen to the rest of the body. Red blood cells are also called erythrocytes, or abbreviated RBC. Each red blood cell (RBC) contains a protein called hemoglobin. Each hemoglobin molecule can bind up to four oxygen molecules to it.These are the red blood cells, also known as erythrocytes. They are one of the very few cell types in the human which do not contain a nucleus (in healthy individuals). 95% of their protein content is haemoglobin, the protein which is responsible for binding oxygen.red blood cellsllamasEdited answer:Red Blood Cells (RBC)red blood cell
Arteries, Veins and Cappillaries

Capillaries are the very small tubes that carry blood. They are the site of gas exchange in the body.

Small Intestion
Yes, a very small one.

where the blood travels from the lungs to left the atria.^^^ This answer is wrong in every salient way. Use the Wikipedia entry here: http://en.wikipedia.org/wiki/Capillary
very small!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
Venules are small blood vessels in the circulatory system that connect capillaries to larger veins. They have thin walls and are responsible for carrying blood back to the heart from the capillaries. Venules appear as small, thin-walled tubes that are more visible than capillaries but smaller than veins.
capillaries are the smallest.
If a vacuum tube takes a very long time to fill during blood specimen collection, it can lead to hemoconcentration where the blood cells become concentrated due to prolonged contact with the tube walls. This can affect the accuracy of test results as the proportion of blood cells to plasma may be altered. Additionally, prolonged exposure to air can cause changes in blood composition and potentially lead to inaccurate test results.
