Cells need to be near capillaries because capillaries carry blood which in turn brings food/fuel to the cells and removes waste products.
Oxygen is delivered to, and carbon dioxide is removed from, cells near the capillary.
Alveolar squamous cells and Capillary endothelial cells.

The critical distance a cell must maintain from a capillary in order to survive is rarely greater than 40 to 200 µm. The role that diffusion plays in this process is that it can maintain the concentration gradient required at the cell.
The liquid was pulled into the small tube by capillary action.
Capillary endothelium
Because the glucose in capillary blood is not fully delivered to the cells yet. Once the blood leaves the capillary and enters the vein, the glucose has then been delivered to the cells and the blood is considered used.
to spread the blood cells so thin that the oxygen can be taken into cells or transferred to other cells.
Capillary washout is a stage of shock that is irreversible. When capillary washout occurs all cell functions stop and the cells die. There is large amounts of potassium acid forced in to the openings of the capillary sphincters and begin to form clots.
