What are the renal arteries?

What are the renal arteries?

Renal artery, one of the pair of large blood vessels that branch off from the abdominal aorta (the abdominal portion of the major artery leading from the heart) and enter into each kidney.

What are interlobular arteries?

Interlobular arteries arise from the arcuate arteries and ascend into the cortex, where they divide into afferent arterioles that supply blood to the glomerular capillaries. The descending vasa recta form capillary networks at various levels within the medulla to supply it with oxygenated blood.

What are the branches of the renal artery?

The dorsal and ventral rami divide into segmental branches within the renal hilum before entering the parenchyma: apical, anterior superior, anterior inferior (middle), inferior and posterior segmental renal arteries.

How many renal arteries are there?

There are two renal arteries—one supplies blood to the right kidney, the other to the left kidney. These arteries branch into many smaller arteries.

What is the function of interlobular artery?

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. En route they give off short branches called the afferent arterioles, which carry blood to the glomeruli where…

What is the difference between renal papilla and minor calyx?

The minor calyces surround the apex of the renal pyramids. Urine formed in the kidney passes through a renal papilla at the apex into the minor calyx; two or three minor calyces converge to form a major calyx, through which urine passes before continuing through the renal pelvis into the ureter.

How would you distinguish between a renal artery and renal vein in a dissected kidney?

Hint: The renal artery helps in supplying the blood to the kidney from the heart while the renal vein removes the blood from the kidney. The renal artery helps in the filtration of the blood in the body through the kidney. It is long, thick, and musculature in nature. It is thin and short.
