The respiratory system is continually challenged by a large amount of foreign material, including viruses, bacteria and fungi inhaled in air from track and arena surfaces during exercise, or from dusty bedding, feed and stable environments. The human excretory system functions to remove waste from the human body. The integumentary system also excretes some water in addition to inorganic salts, lactic acid, and urea in the sweat. Animal is uricotelic. The excretory system is critical to survival. The liver has a small organelle called a peroxisome, which is responsible for taking high levels of toxicity and converting them to less toxic substances. Protein metabolism is the making of amino acids into proteins and the breaking-down of proteins into amino acids. Explain excretion in cockroach. Kidneys Thin-layer chromatographic and enzymatic spectrophotometric anal-yses have failed to detect uric acid in fecal extracts from American cockroaches … They are bean-shaped organs located on either side of the backbone at about the level of the stomach and liver. The liver is part of the digestion system, but also plays a role in the excretory system. living cells in the human body produce metabolic wastes The importance of the excretory system The urinary system, we will place most of our emphasis on this organ system.
