The walls of capillaries are made of one cell cell layer so it is a small diffusion barier. They have the greatest total cross-sectional area and the slowest velocity of blood flow. This enhances exchange.

How is the wall of a capillary suited for the exchange of materials in tissues?
The wall of a capillary is extremely thin.
From what does capillary cell wall receives blood?
The capillary cell wall receives blood from the interstitial fluid.
How does capillary wall receive oxygen?
Capillary walls receive oxygen in the lungs by a process known as diffusion.
What tissue makes up the capillary wall?
Epithelial Tissues?
What is capillary exchange?
Capillary exchange play an important role in homeostasis, it involve the processes of that moves materials across typical capillary wall like diffusion, filtration and reabsorption.
How does the thick capillary wall help blood move slowly?
Capillaries do not vary in thickness, they are very thin. The thin wall permits the exchange between the blood in the capillary and the adjacent tissue cells.
What is a capillary features?
A capillary has a very narrow lumn and very thin wall. These features maximize diffusion of nutrients, wastes, and oxygen.
How does the capillary help substanances pass through it?
Slow flow speed in the capillary increases the efficiency of diffusion. In addition, the thin wall of the capillary helps substances to pass through efficiently.
What are the narrowest kind of blood vessel?
Capillary
What is the pathway of movement for substances traveling across a capillary wall?
Capillaries have very thin walls which are semi-permeable.
What are the specialized lymph capillary structures located in the wall of the small intestine?
Villi
The primary mechanism for exchange of substances across the capillary wall is?
Diffusion
