Urinary System

Urinary System Labeling Use the word bank to label each key part of the urinary system. Kidney Vein Artery Ureter Bladder Internal Sphincter Urethra Video: How do your kidneys work? After watching the video, fill in each blank with the word that completes it. Kidneys help to balance the amount of fluid in your body and detect waste in your blood. Kidneys dispose of waste from your blood by removing it and turning it into urine. Your blood passes through the kidneys between 20-25 times per day, meaning that they filter about 180 liters a day! Blood enters the kidneys through branching arteries. Within the kidney are tiny microscopic structures known as nephrons, which carefully sift through our blood. The nephron has a couple parts to it; a glomerulus, which acts like a sieve filtering out only certain particles to be returned to the blood and a tubule which removes waste as urine and gets it out of the kidney. From the kidney, urine travels down two long tubes known as ureters until it reaches the bladder. From there is gets expelled out of the body as waste. In addition to controlling water balance in the body, the kidneys also regulate blood pressure using a hormone known as renin. They also help control the rate at which red blood cells are formed using a hormone known as erythropoietin. Matching: Match the part of the kidney on the left with its function on the right. Renal artery Carries unfiltered blood to the kidney Renal vein Carries filtered blood away from the kidney Ureter Carries urine from the kidney to the bladder Nephron Filters the blood Bladder Stores urine until eliminated from the body Urethra Eliminates urine waste from the body Nephron Labeling Type the correct number from the word bank below that correctly matches each part. 1 8 7 9 5 4 3 2 6 Dissected Kidney Labeling: Label each structure marked in the picture below by using the following words:-Renal cortex -Renal pyramid -Renal medulla -Renal column -Renal pelvis -Ureter Renal cortex Renal medulla Renal pelvis Renal column Renal pyramid Ureter What are the functional units of the kidneys?
