2. The adult kidney is bean shaped, about the size of a can of soup and weighs about 5 ounces. 3. The right kidney is located in the lumbar region between the T­12 and L­3 vertebra. It lies lower than the left kidney because of the liver's location just above it. 4. The renal sinus is the space within the kidney near the cleft called the renal hilus. It is the entry point of the ureters, blood vessels, and nerves. 5. 1 = renal cortex 2 = renal medulla 3 = adipose capsule 4 = renal fascia 5 = renal capsule 6 = ureter 7 = renal pelvis 8 = renal vein/artery 9 = renal hilus 10 = calyx 6. (1) The renal capsule is a tough fibrous outer skin which protects it from injury and infection. (2) The adipose capsule is a fatty layer that protects the kidney from trauma. (3) The outer renal fascia is dense fibrous connective tissue which keeps the kidney in place inside the abdominal cavity. 7. The renal cortex contains the glomerular capsule and the distal and convoluted tubules and blood vessels. The renal medulla contains the Loop of Henle, the collecting ducts and blood vessels. The renal pelvis connects to the ureter and has extensions called calyces which collect urine. 8. The renal pelvis is the centermost section of the kidneyand is a funnel­shaped tube that connects to the ureter. Extensions of the pelvis called calyces collect urine which drains into the renal pelvis and then into the ureter. 9. About 1200 ml of blood per minute of blood flows into the kidney so that all of the blood can be filetred. 10. (1) Renal artery, (2) Segmental artery, (3) Lobar artery, (4) Interlobar artery, (5) Arcuate artery, (6) Interlobular artery, (7) Afferent arteriole, (8) Glomerular capillaries, (9) Efferent arteriole, (10) Peritubular or Vasa recta capillaries, (11) Interlobular vein, (12) Arcuate vein, (13) Interlobar vein, (14) Renal vein Problem Set 2 11. The kidney filters the blood, reabsorbs needed materials and excretes the rest as urine. 12. The main functions of the kidney are to control the concentration of water and soluble materials, eliminate wastes from the body, regulate blood volume, pH and pressure and control levels of electrolytes

10/22/2018 NursingABC - Module 21/24 13. A nephron is made up of the renal corpuscle and the renal tubule. The renal corpuscle filters the blood and the renal tubule reabsorbs needed materials. 14. The collecting ducts carry urine away from the nephron to be excreted. 15. The renal corpuscle is composed of the glomerulus, a network of tiny blood capillaries surrounded by the Bowman's capsule, a double­walled simple squamous epithelial cup. 16. The glomerular capillaries are the only capillaries in the body which lie between two arterioles rather than between an artery and a vein. 17. The afferent arteriole which runs into the glomerular capillaries is much larger in diameter than the efferent arteriole which drains the glomerular capillaries causing an extremely high blood pressure in the glomerular capillaries. This high pressure forces water and solutes out of the blood and into the glomerular capsule causing
