Unit 11: Urinary System Functions of the Urinary System: ● To regulate water volume, ion salt concentrations, pH levels ● Influences blood pressure, red blood cell production ● Regulates balance of water and salt in the blood Characteristics of the Urinary System: ● Amino acids have nitrogen molecules that may get converted to ammonia, which is toxic.The liver converts it to the less toxic urea compound which gets filtered by the kidney’s nephrons ● Smooth muscle uses peristalsis to move urine out of the kidney, into the ureter, and then into the bladder ● The process of making urine involves: ○ glomerular filtration ○ tubular reabsorption ○ tubular secretion ● The filtrate of the kidney travels through the tubules and empties out through the collecting duct, emptying out what we know as urine ● An adult bladder can hold about 16 ounces (2 cups) of urine Diagram of the Urinary System: Word Parts: PREFIXES: MEANING: a-, an- not; without dia- complete; through dys- painful; difficult hyper- above; above normal; excessive hypo- below; below normal; deficient inter- between intra- within; into poly- many; much ROOTS: albumin/o albumin (a protein) azot/o nitrogen bacteri/o bacteria calcul/o stone carcin/o cancer cyst/o cyst; fluid sac; bladder glomerulus (cluster of capillaries in the kidney where waste products glomerul/o are filtered out of the blood) glyc/o, glycos/o sugar; glucose hem/a, hem/o, hemat/o blood isch/o to hold back lith/o stone; calculus meat/o meatus (passageway into the body) nephr/o kidney; nephron (functional unit of the kidney) noct/o night olig/o scant (very small amount) peritone/o peritoneum py/o pus pyel/o renal pelvis (the part of the kidney where urine collects/drains) ren/o kidney ur/o urine; urinary tract ureter/o ureter urethr/o urethra urin/o urine vesic/o urinary bladder SUFFIXES: -al, -ary, -eal, -ic, -ous pertaining to -cele hernia; swelling; protrusion -emia blood condition -gram record; image -iasis abnormal condition -ion process; state; condition -itis inflammation -lysis breakdown; separation; loosening -lytic pertaining to breakdown or destruction -oma tumor; mass -osis abnormal condition -pathy disease -pexy surgical fixation -sclerosis hardening; thickening -stenosis narrowing -stitial pertaining to standing or positioned -tripsy crushing -uria urination; condition of urine -us structure; tissue; thing
