EXCRETORY PRODUCTS & THEIR ELIMINATION
1.Nitrogenous waste is nitogen containing metabolic waste as of proteins and nucleic acids.
2.Bony fishes and protozoans are ammonotelic. 3.Micturition is carried out by reflex. 4.Protein free fluid is filtered from blood plasma into the Bowman's capsule. 4.Henle's loop plays an important role in concentrating the urine. 5.Glucose is actually reabsorbed in the PCT. 6.Lizard excretes uric acid. 7.Retroperitoneal kidney is present in human beings. 8.JGA is expanded as juxtra glomerular apparatus. 9.Podocytes are specialized cells present in the inner layer of Bowman's capsule. 10.Ultrafilteration,reabsorption,secretion and concentration/dilution are the main processes of urine formation. 11.Sebum is by oil glands present on skin and eliminates waxes,steroids,oils etc. 12.ANF is released by heart. 13.GFR is 125ml/min. 14.Renin is released by kidney cells. 15.Urinary excretion = glomercular filteration-tubular reabsorption + tubular secretion. 16.Dialysis luid = plasma - waste products. 17.Human beings and whales are ureotelic. 18.Renal calculi are the kidney stones, mainly calcium oxalate crystals. |
