no. continuous capillaries form the blood/brain barrier.
Continous capillaries contain tight junctions and are less "leaky " than fenestrated capillaries. They only allow the movement of water and small ions, whereas fenestrated capillaries contain many fenestrae or pores and allow many molecules with the exception of medium and large proteins to pass

There are three main types of capillaries: continuous, fenestrated, and sinusoidal. Continuous capillaries have a complete endothelial lining and are the most common type, found in muscles and the blood-brain barrier. Fenestrated capillaries contain small pores that allow for increased permeability, primarily located in areas like the kidneys and intestines. Sinusoidal capillaries have larger gaps between endothelial cells, facilitating the exchange of larger molecules and cells, and are found in the liver, spleen, and bone marrow.
Pores (fenestrae) through the cells that allows the passage of large molecules such as protiens.

the endothelial cells have pores (windows) to allow rapid movement of solutes and water.
Yes, the fenestrated endothelium of capillaries, along with the basement membrane and filtration slits in podocytes in the kidney, make up the filtration membrane responsible for the filtration of blood in the glomerulus. The fenestrations in the endothelium allow for the passage of small molecules and fluids.
The most permeable vessels in the body are the capillaries, particularly the fenestrated and sinusoidal types. Fenestrated capillaries have small pores that allow for increased permeability to small molecules and water, while sinusoidal capillaries have larger openings that facilitate the passage of larger proteins and cells. This high permeability is crucial for processes such as nutrient exchange and immune responses in tissues.
Yes, the renal corpuscle contains fenestrated capillaries. These specialized capillaries, known as glomerular capillaries, have small pores that allow for the filtration of blood while retaining larger molecules like proteins and cells. This structure is crucial for the kidney's filtration process, enabling the formation of urine while maintaining the necessary balance of substances in the blood.
