GENERAL HISTOLOGY

Detailed explanation-1: -An interlobar artery extends along the boundary of each renal lobe (renal column) and then branches at right angles to form an arcuate artery that runs along the corticomedullary junction (Fig. 11-7). Interlobular arteries branch from the arcuate artery and extend into the cortex.

Detailed explanation-2: -The renal artery branches into smaller arteries called the afferent arterioles. The blood travels from the afferent arterioles to the glomerulus, located in the nephron.

Detailed explanation-3: -structure of the kidney Many arteries, called interlobular arteries, branch off from the arcuate arteries and radiate out through the cortex to end in networks of capillaries in the region just inside the capsule.

Detailed explanation-4: -The glomerulus, the filtering unit of the kidney, is a specialized bundle of capillaries that are uniquely situated between two resistance vessels (Figure 1). These capillaries are each contained within the Bowman’s capsule and they are the only capillary beds in the body that are not surrounded by interstitial tissue.
