capillaries
Capillaries via osmosis
Capillaries. they have such thin walls that substances can easily diffuse through them.
Tiny blood vessels that allow substances to pass between the blood and body tissues are called
Blood vessels do not carry air. Blood vessels carry blood, and this blood can carry dissolved gas molecules.
No, capillaries are what allows substances to go from the walls of the small intestine into your cells. Veins are what carry the blood (with cells inside) to the heart to be oxygenated.
The main transport systems are the circulatory systems, in which substances are dissolved or suspended in liquid and carried from one part of the body to another in a system of tubes are called "Blood Vessels". It's function is mainly bumping the blood, so it can move through the whole body.
Blood
I know oxygen and if you smoke carbon monoxide is dissolved in the blood. I think salts, sugars, vitamins and minerals and all dissolved into the blood. Also alcohol when you drink it gets dissolved in the blood.
capillaries have walls thin enough to allow the exchange of materials between cells and the blood. Their extensive branching provides a sufficient surface area to pick up and deliver substances to all cells in the body.
White Blood Cells, water and dissolved substances
Capillaries - The endometrium (epithelial lining/wall) of the capillaries is only one cell thick optimizing diffusion/osmosis between it and the tissue cells of the body
