Facts about Capillaries 1: the diameter

Can you tell me the diameter of capillaries? The diameter is around five to 10 micrometres.

Facts about Capillaries 2: the function

Facts about Capillaries 9: the location of fenestrated capillaries

The fenestrated capillaries are located in various locations such as pancreas, intestines, glomeruli of the kidney, and endocrine glands. Get facts about body system here.

Facts about Capillaries 10: Sinusoidal capillaries

The white and red blood cells can easily pass the blood vessels due to the presence of sinusoidal capillaries. You can find these capillaries in the lymph nodes, adrenal glands and bone marrow. The liver and spleen have the discontinuous sinusoidal capillaries. Without the presence of capillary wall, it will be impossible for the waste and nutrient to be transported from the cells.
