Capillaries.
Red cells that group together normally tend to do so in rouleaux; those that stay as individuals will have greater opportunities to absorb oxygen. If they pass through capillaries individually will be more efficient as transporters of oxygen.
Lumen refers to the inner space within a tubular structure such as a blood vessel or intestine, through which substances pass. It is not a measure of size like red blood cells but rather the open space within the structure. Red blood cells are typically around 6-8 micrometers in diameter, much larger than the lumen of small blood vessels.
Capillaries are tiny blood vessels that consist of a single layer of endothelial cells. They have a diameter just large enough for red blood cells to pass through one at a time. Capillaries connect arterioles and venules in the circulatory system.
Red blood cells travel in single file primarily due to their biconcave shape and the narrow diameter of capillaries, which are often only slightly larger than the cells themselves. This arrangement allows them to efficiently navigate through small blood vessels, minimizing turbulence and maximizing the surface area for gas exchange. Additionally, the flexibility of red blood cells enables them to deform and squeeze through tight spaces, facilitating this single-file movement.
Microvessels, such as capillaries, are so small that blood cells must pass through them in single file. This allows for efficient exchange of oxygen and nutrients between blood and tissues. The small size of these vessels also facilitates the removal of waste products from tissues.
No, a blood cell is not a Protista. Blood cells are not classified as Protista, which are single-celled eukaryotic organisms. Blood cells are specialized cells found in the circulatory system of animals.
The blood cells must move through the capillaries in a single file line because the diameter of the capillary is only slightly larger than the diameter of the blood cells - there isn't room for two blood cells to go through side by side.
Capillaries
In adults they are mostly produced in the bone marrow. There are situations where they can be produced elsewhere.
It is blood cells

The skeleton give structure to the body as well as protects organs and parts of it make red blood cells, platelets and white blood cells.
Blood cells and single-celled organisms share some similarities in their structure and function. Both blood cells and single-celled organisms are enclosed by a cell membrane, have specific functions within the organism, and can replicate to maintain their population. However, blood cells are specialized for carrying oxygen and nutrients in multicellular organisms, whereas single-celled organisms must perform all functions necessary for survival on their own.
Your blood is not single-celled, is is muti-celled because all of the red blood cells in your blood.
Structures that can be seen through a microscope include cells, bacteria, fungi, blood cells, and tissues. These structures are magnified to allow for detailed observation and analysis.
