urinary system
UA/ micro ch 15
| Question | Answer |
|---|---|
| what are the functions of the urinary system? | to remove waste products from the blood and produce urine |
| this hormone is produced by the kidney and aides with RBC formation in the bone marrow | erythropoietin |
| this enzyme is produced by the kidneys that aids in raising blood pressure | renin |
| kidneys are located between the muscles of the back peritoneal cavity also known as | retroperitoneal |
| outer layer of the kidney that contains nephrons | cortex |
| microscopic functional units of the kidney | nephrons |
| bell shaped collection of very tiny intertwined capillaries | glomerulus |
| double walled cup surrounding the glomerulus | bowmans capsule |
| renal tubule consists of | proximal convoluted tubule; loop of henle; distal convoluted tubule |
| inner layer of the kidney | medulla |
| medulla consists of triangular tissues called | renal pyramids |
| regulate fluid and electrolyte balance and removes wastes from the blood | excretion |
| produces and stores urine | secretion |
| remove waste | elimination |
| collecting vessel prior to ureter | renal pelvis |
| the 3 physiological functions of the nephron as it produces urine | filtration; reabsorption; secretion |
| consists of the glomerulus and bowmans capsule | renal corpuscle |
| capillaries | glomerulus |
| extension of renal tubule that encapsulates glomerulus | Bowmans capsule |
| carries blood to glomerulus | afferent arteriole |
| carries blood from glomerulus | efferent arteriole |
| flow of urine | kidneys>ureter>urinary bladder>urethra>urinary meatus |
| connects the kidneys to the bladder | ureters |
| hollow muscular sac that stores urine | bladder |
| tube that carries urine from the bladder to the outside of the body | urethra |
| urine is composed of | 95% water; urea; uric acid; creatinine;salts; pigments |
| characteristics of normal urine | color;clarity;odor;specific gravity;pH |
| normal urine has a color of | pale yellow to deep golden |
| the clarity of normal urine is | clear |
| normal should should smell | strong but not bad |
| normal urine has a specific gravity of | 1.003-1.030 |
| this represents relative acidity or alkalinity of a solution | pH |
| normal urine pH is | 6.0 which is slightly acidic |
| normal urine does not contain the folowing | protien;glucose or ketones |
| cessation of urine production | anuria |
| painful urination | dysuria |
| urinary incontinence at night | enuresis |
| presence of blood in the urine | hematuria |
| scanty urine out put | oliguria |
| excessive thirst | polydipsia |
| abnormally large amounts of urine | polyuria |
| pus in the urine | pyuria |
| need to void immediately | urgency |
| inflammation of the urinary bladder | cystis |
| distension of the pelvis and calyces of the kidney | hydronephrosis |
| bacterial infection of the renal pelvis of the kidney | pyelonephritis |
| kidney stones | renal calculi |
| malignant tumor of the kidney occurring in choldhood | Wilms tumor |
| mechanical filtering process using the peritoneal membrane as a filter | peritoneal dialysis |
