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.
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
Fenestrated capillaries
continuous capillaries continuous capillaries
no. continuous capillaries form the blood/brain barrier.
fenestrated
The renal corpuscle filtration barrier is composed of: the fenestrated endothelium of glomerular capillaries, the fused basal lamina of endothelial cells and podocytes, and the filtration slits of the podocytes.
glomerular
true
Pores (fenestrae) through the cells that allows the passage of large molecules such as protiens.
The filtration membrane in the nephron is formed by the fenestrated endothelium of the glomerular capillaries, the glomerular basement membrane, and the podocytes of the Bowman's capsule that wrap around the capillaries. These structures work together to selectively filter and prevent the passage of larger molecules like proteins into the urine while allowing smaller molecules to be filtered.
Capillaries are blood vessels that are composed of endothelium only. They are the smallest blood vessels in the body and are responsible for the exchange of gases, nutrients, and waste products between the blood and tissues.
