SBGR Urinary System
SBGR ALH 165 Urinary System (2012 LS)
| Question | Answer |
|---|---|
| Urinary system | Eliminates excess water, salts and physiological wastes by producing urine |
| Kidneys | Perform the excretory functions of the urinary system |
| Urine | A fluid containing water, ions and small soluble compounds |
| Ureters | Receives the urine from the kidneys and conducts it to the urinary bladder |
| Urinary bladder | Receives and stores urine prior to its elimination from the body |
| Urination | Ejection of urine |
| Urethra | Passageway that conducts urine from the urinary bladder to the outside of the body |
| Hilum | Point of entry for the renal artery and renal nerves |
| Renal cortex | Superficial region of the kidney in contact with the fibrous capsule |
| Renal medulla | Extends from the renal cortex to the renal sinus |
| Renal pyramid | Conical structure extending from the cortex to the renal sinus |
| Renal column | Separates adjacent pyramids |
| Nephron | Microscopic structure that performs essential functions of the kidney |
| Renal corpuscle | Spherical structure consisting of the glomerular capsule and the glomerulus |
| Nephron loop | Establishes an osmotic gradient in the renal medulla |
| Collecting system | A series of tubes that carry tubular fluid away from the nephron |
| Cortical nephrons | Make up 85% of all nephrons and are located almost entirely within the superficial cortex of the kidney |
| Glomerulus | Capillary knot |
| Vasa recta | Long, straight capillaries that parallel the nephron loop |
| Urea | By-product of the breakdown of amino acids in the liver |
| Creatinine | Generated in skeletal muscle tissue through the breakdown of creatine phosphate |
| Uric acid | Waste product formed during the recycling of the nitrogenous bases of RNA molecules |
| Filtration | Blood pressure forces water and solutes across the membranes of the glomerular capillaries and into the capsular space |
| Reabsorption | Removal of water and solutes from the tubular fluid and their movement across the tubular epithelium and into the peritubular fluid |
| Secretion | Transport of solutes from the peritubular fluid, across the tubular epithelium, and into the tubular fluid |
