Capillaries are very thin and form almost web like structures. Because of how thin they are, they have a favorable surface area to volume ratio. Capillaries increase the surface area available for gas to diffuse into the blood. More suface area leads to more gas exchange.
The lymphatic capillaries are small, thin-walled vessels that collect excess tissue fluid (lymph) from the interstitial spaces and return it to the bloodstream. This helps maintain fluid balance in the body and plays a crucial role in the immune system by transporting immune cells and proteins.
