Anatomy QIV:PIII
The Urinary System
| Question | Answer |
|---|---|
| three functions of the urinary system | maintain chemical consistency of blood, filter many liters of fluid from blood, send wastes, toxins, and water out of the body |
| 4 organs of the urinary system | kidneys, ureters, urinary bladder, urethra |
| uriniferous tubules composed of two main parts | nephron, collecting ducts |
| nephron made up of two parts | renal corpuscle, renal tubules |
| renal corpuscle made up of two parts | glomerulus, bowman's capsule |
| tuft of blood capillaries surrounding the corpuscle | glomerulus |
| capsule surrounding the corpuscle | bowman's capsule |
| filtrate of blood leaves the kidney capillaries | filtration |
| most nutrients, water, and essential ions reclaimed in | resabsorption |
| active process of removing undesirable molecules | secretion |
| receive urine from distal convoluted tubules | collecting tubules |
| carry urine from the kidneys to the urinary bladder | ureters |
| a collapsible muscular sac which stores and expels urine | urinary bladder |
| part of the male urethra which passes through the prostate gland | prostatic urethra |
| part of the male urethra which passes through the urogenital diaphragm | membranous urethra |
| part of the male urethra which passes through the length of the penis | penile (spongy) urethra |
| three parts of the male urethra from proximal to distal | prostatic, membranous, spongy (penile) |
| small lobes of the kidney outlined by vessels | renal pyramids |
| space between the base of the renal pyramids and the capsule | cortex |
| where the cortex dips between each of the renal pyramids | renal column |
| the adipose capsule surrounding the kidney | pararenal fat |
| the flow of urine from the renal corpuscle is (12 structures): | renal corpuscle, proximal convoluted tubule, loop of henle, distal convoluted tubule, collecting ducts, papillary ducts, minor calies, major calices, renal pelvis, ureters, bladder, urethra |
