Anatomy urinary final Flashcards
What are the components of the Urinary system?
Kidneys
Urinary tract
What are the parts of the Urinary tract?
Ureters
Urinary bladder
Urethra
What are the functions of the urinary tract?
Excretion
Elimination
Regulation of blood solutes and blood volume
Conserve valuable nutrients
Detoxifies poisons and de-aminates amino acids (glutamate) for use by other tissues
the removal of metabolic waste from the circulatory system (kidneys) is called?
Excretion
discharge of wastes into the environment (bladder and urethra) is called?
Elimination
How does the urinary system regulate blood?
Controls blood volume and blood pressure by adjusting the volume of water eliminated in urine
Controls plasma concentration of several ions (Na, K, Cl)
Produces calcitriol for Ca control
What are the smallest functional units of the kidneys called?
nephrons
Which kidney is slightly lower?
right
kidneys are
Highly vascular
Retroperitoneal
Kidneys are stabilized by what?
Stabilized by overlying peritoneum, adjacent organs, and connective tissue capsule
What are the two components in nephrons?
Renal corpuscle = glomerulus (ball of capillaries) and glomerular capsule
Renal tubule = up to 2” long
What is glomerlus
Definition: Glomerulus is a common term used in anatomy to describe globular structures of entwined vessels, fibers, or neurons. Glomerulus is the diminutive of the Latin glomus, meaning “ball of yarn”.
Where is glomerulus found?
What happens here?
Found in upper cortex (cortical) and lower cortex (juxtamedullary)
Filtration, due to capillary pressure, takes place here, water and solutes collecting in the glomerular capsule
