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 |
