Are the capillaries in the glomerulus fenestrated?
Glomerular Filtration The endothelial cells that line the glomerular capillaries are specialized for their function. These capillaries are fenestrated. The root word for fenestra means “window”.
What type of capillaries are found in the renal glomerulus?
The glomerulus receives its blood supply from an afferent arteriole of the renal arterial circulation. Unlike most capillary beds, the glomerular capillaries exit into efferent arterioles rather than venules….Glomerulus (kidney)

What are Fenestrations in kidneys?
Fenestrations are round or ovoid transcellular holes through the most attenuated part of the EnC cytoplasm. They are found in the endothelium of organs where a higher rate of exchange between intra- and extravascular compartments is required.
Are glomerular capillaries continuous or fenestrated?
They are particularly important in the glomeruli of the kidneys, as they are involved in filtration of the blood during the formation of urine. The capillaries have small openings in their endothelium known as fenestrae or fenestra, which are 80 to 100 nm in diameter.
Where are fenestrated capillaries found?
Fenestrated capillaries have intracellular perforations called fenestrae are found in endocrine glands, intestinal villi and kidney glomeruli and are more permeable than continuous capillaries.
Which capillaries are fenestrated types?
Fenestrated capillaries These are found in some tissues where there is extensive molecular exchange with the blood such as the small intestine, endocrine glands and the kidney.
Which of the following organs would be most likely to contain fenestrated capillaries?
Are all capillaries fenestrated?
There are three primary types of capillaries—continuous, fenestrated, and discontinuous or sinusoidal that are found in different regions of the body, and specialized capillaries in the brain make up the blood-brain barrier.
Where can fenestrated capillaries be found?
You have fenestrated capillaries in your kidneys, intestines, pancreas and endocrine glands. These organs need a continuous exchange of nutrients, waste and substances between the capillaries and tissues. The pores in the capillaries make it easier for this exchange to happen.
