Interactive Physiology Anatomy Review: Urinary System Graphics are used with permission of: adam.com ( http://www.adam.com/ ) Benjamin Cummings Publishing Co ( http://www.aw.com/bc ) Instructions: (please read this first) This lab is a self driven activity that requires you to use your CD that you got with your book. You will be going through the interactive physiology topics for the Respiratory. You will be doing the topics 1) Anatomy Review: Urinary System Below are several pages that give an overview of what you see and do in the interactive tutorials. This overview is for your benefit to look over later and refresh your mind. There may be some pictures to label below but they will not be graded on this lab assignment. However, these pictures may show up on a quiz or test later and you will need to label it then. This assignment is worth 20 points and will be graded by the answers that you put on the last few pages where I have included 16 questions. I believe it would work best to do the questions at the same time that you are doing the interactive activities. The Urinary System • The urinary system rids the body of waste materials and controls the volume and composition of body fluids. • Highly specialized cells in the kidneys are essential to these processes. • The urinary system is composed of paired kidneys and ureters, the urinary bladder, and the urethra. • Urine is produced in the kidneys, and then drains through the ureters to the urinary bladder, where the urine is stored. Urine is eliminated from the body through the urethra. • Label this diagram:

Interactive Physiology 2 External Structure of the Kidneys Each bean-shaped kidney is embedded in a fatty adipose capsule. • The kidneys are retroperitoneal, lying against the dorsal body wall in the upper abdomen. • An adrenal gland, which is part of the endocrine system, lies on top of each kidney. • Several structures enter or exit the concave surface of the kidney at the renal hilus, including the ureter and the renal vein, which drains into the inferior vena cava. • Label this diagram: Blood Supply of the Kidneys When the renal vein is removed and the kidney is shown in frontal section, you can see the deeper renal artery and its connection to the abdominal aorta. • Branching from the renal artery are the segmental and lobar arteries. • Together, these vessels provide the kidneys with a rich blood supply under high pressure that allows them to continuously filter and cleanse the blood. • Label this diagram:

Interactive Physiology 3 Internal Structure of the Kidney Internally, the human kidney is composed of three distinct regions: 1. Renal Cortex • The outermost layer is called the renal cortex. It contains about one million nephrons, the filtering units that form urine. • Types of Nephrons:
