Facilitated diffusion is a type of passive transport that allows substances to cross membranes with the assistance of special transport proteins. Some substances that can pass through the walls of the capillary via facilitated diffusion include:

1. Glucose: Glucose is a sugar that our bodies use for energy. It is too large to pass through the capillary walls on its own, so it uses a transport protein to help it move across.

2. Amino acids: These are the building blocks of proteins. Like glucose, they are too large to pass through the capillary walls on their own and require a transport protein.

3. Ions: Certain ions, such as potassium and sodium ions, can also pass through the capillary walls via facilitated diffusion. They use ion channels, which are a type of transport protein, to move across the membrane.

4. Water: While water can pass through the capillary walls on its own, it can also use a type of transport protein called aquaporins to move across more quickly.

Remember, facilitated diffusion does not require energy as it moves substances from an area of high concentration to an area of low concentration.
