so that they can go through them as the are very thin
Capillaries are very thin blood vessels. Oxygen and nutrients and hormones can pass through the walls of the capillaries and reach the body's cells, while red blood cells remain in the capillaries.
capillaries
blood
As red blood cells travel through capillaries oxygen is released (disassociated) with hemoglobin. The oxygen then diffuses down it's concentration gradient into the tissues.
Capillaries take oxygen and nutrients from the blood to the cells in the body. They also remove waste products, such as carbon dioxide, from the cells.
The blood cells are in the capillaries and are moved along in the capillaries. Your question makes no sense.
Both red and white blood cells pass through the capillaries.

No, not all cells in the circulatory system are blood cells. The circulatory system also includes blood vessels like arteries, veins, and capillaries that transport blood throughout the body. Blood cells are a component of the blood itself, along with plasma.
Cells
Capillaries change color as they pass by body cells as the blood they contain loses oxygen. Oxygen-rich blood has a brighter color than oxygen-poor blood.

Capillaries do not occur in cells.Capillaries are larger than cells, indeed capillaries are made of cells.Capillaries are the smallest blood vesicles.
The brain has veins, capillaries, and arteries which contain blood cells.
