The leakiest capillaries, which allow large substances such as cells to cross the capillary walls are called sinusoidal capillaries.
Sinusoidal capillaries are a unique kind of capillaries that are wide in diameter. The diameter of a sinusoidal capillary is 30 to 40 nm.
Sinusoidal capillaries can be found in the liver, spleen, and bone marrow. In the spleen, sinusoidal capillaries help in the filtration of blood. They remove broken red blood cells, antigens and other pathogens remains in the blood.
Sinusoidal capillaries are known as leakiest capillaries because all other capillaries have a narrow diameter and do not allow the passing of large substances. Sinusoidal capillaries are the only ones with a large diameter that allows the passing of larger substances.
