Histo Urinary System Flashcards
The urinary system consists of:
kidneys,
ureters,
urinary bladder,
urethra
Vital in maintaining homeostasis of the body. They regulate blood pressure, blood composition, and fluid volume of the body, produce urine; and maintain acid-base balance
kidney
Kidney produce two important hormones
renin
erythropoietin
regulates blood pressure and maintains proper filtration pressure for the kidneys.
Renin
promotes red blood cell formation in the red bone marrow.
erythropoietin
functional unit of the kidney is the
nephron
nephron is subdivided into two components.
renal corpuscle
renal tubule
consists of a tuft of capillaries
renal corpuscle
renal corpuscle consists of a tuft of capillaries (glomerulus) rounded by an inner visceral and an outer parietal layer of epithelial cells, the?
glomerular (browman’s) asule
two types of nephron in the kidney
Cortical nephrons
Juxtamedullary nephrons
Are located in the cortex of kidney and the kidney
cortical nephrons
are situated near the corticomedullary section:
juxtamedullary nephrons
produce a hypertonic environment in the interstitium of the kidney medulla, a condition that is necessary for the production of concentrated (hypertonic urine).
