Unformatted text preview: Final Review Chapters 25-28 Anatomy II Chapter 25: The Urinary System What are the Functions of the Kidneys? Kidney Functions Filter and Purify Everything in the Blood Regulate Volume and Chemical Makeup of the Blood Maintain the Proper Balance Between Water and Salts, Acids and Bases Only Place that Eliminates Hydrogen in the Body Production of Rennin to Help Regulate Blood Pressure and Erythropoietin to Stimulate RBC Production Activation of Vitamin D Describe the Other Urinary System Organs. Urinary System Organs Urinary Bladder Provides a temporary storage reservoir for urine Ureters Transport urine from the kidneys to the bladder Urethra Transports urine from the bladder out of the body Describe the Anatomy of the Kidney. Anatomy of the Kidney Cortex Light colored, granular superficial region Medulla Exhibits cone-shaped renal pyramids Pyramids are made up of parallel bundles of urine-collecting tubules Renal columns are inward extensions of cortical tissue that separate the pyramids The medullary pyramid and its surrounding capsule constitute a lobe Renal Pelvis Flat, funnel-shaped tube lateral to the hilus within the renal sinus Major Calyces Large branches of the renal pelvis Collect urine draining from papilla Papilla: Tip of renal pyramid Empty urine into the pelvis Minor Calyces Cup the renal pyramid Fill in the Blank for the Following Diagram. Blood Pathway in the Kidneys A: Renal Artery B: Lobar Artery C: Interlobular Artery D: Glomerulus E: Interlobular Vein F: Interlobar Vein G: Inferior Vena Cava Describe Nephrons. Nephrons Structural and functional units that form urine Parts Glomerulus A tuft of capillaries associated with a renal tubule Glomerular (Bowmans) Capsule Blind, cup-shaped end of a renal tubule that completely surrounds the glomerulus Renal Corpuscle The glomerulus and its Bowmans capsule Glomerular Epithelium Fenestrated epithelium that allows solute-rich, virtually protein-free filtrate to pass from the blood into the glomerular capsule Identify the Following Items in the Nephron. Nephron A: Distal Convoluted Tubule B: Podocyte C: Proximal Convoluted Tubule D: Loop of Henle E: Collecting Duct Identify the Following Items in the Glomerulus. Glomerulus A: Afferent Arteriole B: Efferent Arteriole C: Juxtoglomerular Apparatus D: Glomerulus E: Bowmans Capsule F: Proximal Tubule Describe the Renal Tubule.Describe the Renal Tubule....
