excretory system
-The main organ of excretion is a pair of kidneys. These are compact, bean like structures situated towards the back of the body cavity on both sides of the spine.
-The frog excretes urea. It is carried by blood into the kidney where it is separated and excreted.
-Each kidney is composed of several structural and functional units called nephrons. Their job is to filter blood of urea and convert it into urine.
-Ureter emerges from the kidney as urinogenital duct in the male.
-A common ureter opens into the cloaca.
-A thin-walled urinary bladder is located under the rectum, which also opens into the cloaca.
-Through the liver and digestive system; undigested food and some wastes are excreted.
-Additionally, carbon dioxide and water are excreted through lungs and skin.
