The excretory system is the system of an organism that made up of several organs to discharge wastes from body (New Health Advisor, n.d.) and regulate the composition and concentration of internal body fluids (Shmoop University, n.d.). Kangaroo has a similar excretory system with most of the mammals and adapt to minimize water loss as they remove waste products especially their habitat is dry environment. Skin, lungs and kidney are the primary excretory system organs while liver, gallbladder, urinary bladder, ureter and urethra are accessary excretory system organs (New Health Advisor, n.d.).
The skin keeps the water in and prevents evaporation (Muller, n.d.). The sweat glands carry out the excretory function by producing sweat that comprises of salt, oils, water, and other unnecessary substances to remove from body (New Health Advisor, n.d.).…show more content… The liver is the main metabolic site that is crucial for detoxification. Biochemical processes can produce toxic byproducts as metabolic wastes and these wastes must be removed (Farabee, 2001). For example, byproduct of protein metabolism is ammonia that has to be converted into a less toxic compound which is urea for excretion (Muller, n.d.). Then, urea is filtered and excreted by the kidneys as urine. Gallbladder is the storage of bile produced by liver to breakdown fats, ethanol and other acidic wastes (New Health Advisor,
