From the blood to the cell.
oxygen
capillaries
the direction of movement of oxygen from the air you breathe and to dispose of excess.
capillaries between the cells in the lungs or the capillaries between the cells in the body
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.
Capillaries - they are the smallest vessels that serve as arteries and veins.
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
Oxygen is supplied to the body tissues by a series of blood vessels from arteries, arteriolles, to capillaries.
diffusion
Oxygen and carbon dioxide
I dont think there are such things as oxygen cells. However, there are red blood cells (erythrocytes) that have hemoglobin, a molecule that oxygen can bind to. Throughout literally every cell in your body, there are capillaries. These capillaries deliver red blood cells to all of your cells, including your muscle cells.
