Question
THE PELVIC REGION: THE URINARY SYSTEM 1. What is the name of the tubes that pass through the renal pyramids on their way to the minor ca lyces? Beginning with the renal artery, number the following blood vessels in sequence as blood is traveling through the kidney. Renal artery 2. Cortical radiate artery Interlobar artery Blood that leaves the efferent arteriole enters into what capillaries next? Segmental artery Afferent arteriole Arcuate artery 3. There are two kinds of nephrons-cortical nephrons and juxtaglomerular nephrons. Which one has its glomerular capsule nearest the border of the renal cortex and renal medulla? 4.Explanation / Answer
1. The pyramids consist mainly of tubules that transport urine from the cortical, or outer, part of the kidney, where urine is produced, to the calyces, or cup-shaped cavities in which urine collects before it passes through the ureter to the bladder. The point of each pyramid, called the papilla, projects into a calyx.
2. Renal artery Interlobar arteries Arcuate arteries Interlobular arteries Afferent arterioles Glomerular capillaries Efferent arterioles Peritubular capillaries/vasa recta Interlobular veins Arcuate veins Interlobar veins Renal vein.
3. Efferent arterioles Peritubular capillaries/vasa recta.
4. Medullary refers to the renal medulla, which in these nephrons are near the medulla.Juxtamedullary nephrons, which have their glomeruli near the corticomedullary border.
