In the glomerulus, a tuft of capillaries in the renal cortex, blood is filtered through the porous capillary walls.

The glomerulus receives its blood supply (that need to be filtered) from an afferent arteriole of the renal arterial circulation and the glomerular capillaries exit into efferent arterioles. The glomerular filtration rate is a rate at which blood is filtered through all of the glomeruli.

In the glomerulus, a tuft of capillaries in the renal cortex, blood is filtered through the porous capillary walls. This implies the correct answer is glomerulus

The glomerulus tuft carries out the first stage in blood filtration in the kidney.

Further Explanation

The glomerulus is a network of capillaries (small vessels) that are surrounded by the glomerular capsule (also known as Bowman’s capsule) where urine is filtered. This network of small blood vessels is also known as tuff and is situated at the beginning of the nephron within the kidney. Structurally, the tuff is supported by mesangial cells and it is also made up of tubes with a central lumen.

The major responsibility of the glomerulus is to filter blood plasma and generate glomerular filtrate. The produced glomerular filtrate then moves down through the nephron (which is the functional part of the kidney) tubule to form urine.

However, the glomerulus gets its blood supply from the afferent arterioles, that is, the blood that is present in the glomerular capillaries is made possible by an afferent arteriole and not venule. The afferent arterioles control the free flow of blood in the glomerulus.

Therefore, in the glomerulus a tuft of capillaries in the renal cortex, blood is filtered through the porous capillary walls.
