1. 4 Contributions 1) Blood comp
of the Urinary 2) Blood osmolarity
System 3) pH balance
4) Hormone production
2. 8 Functions of 1) Excretes nitrogenous/metabolic waste
the Urinary Sys- 2) Regulates of H2O
tem 3) Regulates electrolytes
4) Regulate pH (H+)
5) Regulates blood pressure and volume
6) Regulates blood glucose levels
7) Assists with RBC production
8) Activates Vitamin D
3. Organs Involved 1) Kidneys (functional organs)
in the Urinary 2) Ureters (transports from kidney)
System 3) Urinary bladder (urine storage)
4) Urethra (terminal passage way)
4. Kidneys Loca- Between the last thoracic and 3rd lumbar discs
tion Protected by 11th and 12th ribs
5. External Anato- Renal helium-indent where ureter emerges
my of Kidneys 3 tissues-renal capsule, adipose capsule, renal fascia
6. Renal Capsule Inner most tissue
Barrier against trauma
Maintains shape
7. Adipose Capsule Mass of fatty tissue
Protects from trauma
Holds kidney in place
8. Renal Fascia Outer most tissue layer
Thin layer of connective tissue
Anchors to surrounding structures and ab wall
9. Internal Anatomy Renal cortex-superficial region
of Kidneys Renal medulla-inner region
, HESI Entrance Exam
10. Structure of Re- Splits into renal pyramids
nal Medulla Contains nephrons
Aides in H2O reabsorption
11. Urinary Bladder Pelvic cavity, posterior to pubic symphysis
Location
12. Why Bladder is Limited space due to uterus laying superior to bladder
Smaller in Fe-
males
13. Nephron Functional unit of kidney
Forms urine
14. Urine Process Nephrons drain into ducts
Ducts flow into renal calyces
Renal calyces drains into renal pelvis, to ureter then to
bladder
15. 2 Parts of 1) Renal corpuscle
Nephrons 2) Renal tubule
16. Renal Corpus- Filters blood plasma
cle Function and 1) Glomerulus (capillary network)
Parts 2) Glomerular Capsule (cup surrounding glomerulus)
17. Renal Tubule Filtered fluid into 3 sections
Function and 1) Proximal tubule
Parts 2) Descending and ascending loops
3) Distal convuluting tubules
18. 3 Aspects of Re- 1) Glomerular filtration
nal Physiology 2) Tubular reabsorption
3) Tubular secretion
19. Glomerular Fil- 1.5-2.5 liters secreted daily
trate Fluid enters capsulary space
Filtrates H20, small solutes
Blocks plasma proteins, blood cells, platelets
