BIOSC-116 Lecture Notes - Lecture 12: Hemoglobin, Urobilinogen, Creatinine
Document Summary
Homeostatic effector for: i. e. functions of the renal system. Nitrogenous waste management nitrogen containing wastes are eliminated in the urine. These wastes are: creatinine from the breakdown of creatine in muscles, uric acid from the breakdown of nucleic acids (dna, rna, urea from the breakdown of protein, ammonium ions. Ions/electrolytes na+, k+, hco3-, cl- are all eliminated in the urine. Ph/hydrogen ions if there are too many h+ in the blood, the kidneys will eliminate them in the urine. Organic nutrients like urobilinogen (from the breakdown of hemoglobin) will be eliminated in the urine. The nephron is the functional unit of the kidney (i. e. it makes the urine). If you have extra water in your blood, then you will make a large volume of a dilute urine. There are 2 parts to the nephron: glomerulus a tuft of capillaries. Unique in 2 ways (discussed below: renal tubule has 4 parts, bowman"s capsule functions in filtration.
