Hint: The glomerulus (plural glomeruli), is a community of small blood vessels (capillaries) called a tuft, placed at the start of a nephron inside the kidney. The tuft is structurally supported by using the mesangium - the distance between the blood vessels - made from intraglomerular mesangial cells, The capillaries include a tube covered using endothelial cells with an important lumen. The gaps among those endothelial cells are called fenestrae.

Complete answer:
• Blood enters the capillaries of the glomerulus with the aid of a single arteriole called an afferent arteriole and leaves by using an efferent arteriole.
• The resistance of the different arterioles is enough hydrostatic pressure in the glomerulus to offer the force for ultrafiltration.
• The main feature of the glomerulus is to filter plasma to provide glomerular filtrate, which passes down the length of the nephron tubule to form urine.
• The charge at which the glomerulus produces filtrate from plasma (the glomerular filtration price) is much better than in systemic capillaries because of the specific anatomical characteristics of the glomerulus.
• Unlike systemic capillaries, which get hold of blood from excessive-resistance arterioles and drain to low-resistance venules, glomerular capillaries are connected in both ends to excessive-resistance arterioles: the afferent arteriole, and the efferent arteriole.
• This association of two arterioles in a collection determines the high hydrostatic strain on glomerular capillaries, that's one of the forces that favour filtration to the Bowman's tablet.
• If a substance has passed through the glomerular capillary endothelial cells, glomerular basement membrane and Blood exits the glomerular capillaries via an efferent arteriole as opposed to a venue, as is seen in the majority of capillary systems.
• This gives tighter control over the blood flow with the flow via the glomerulus.

Hence, the correct answer is option (C).

Note: Because arterioles dilate and constrict more with ease than venules, as a result of their thick round clean muscle layer (tunica media). The blood exiting the efferent arteriole enters a renal venule, which in flip enters a renal interlobular vein after which into the renal vein., then it enters the lumen of the tubule and is called glomerular filtrate.
