Ch 26: Urinary System Flashcards
Functions of urinary system
-urine
-excrete waste products
-Regulate blood volume and pressure
-Regulate blood solute, red blood cells, synthesis, vitamin D
What does urine consist of?
Water,ions ,urea, and toxic substances
Does not contain glucose unless diabetic
Erythropoietin
Regulation of red blood cell synthesis
Is EPO produced in red bone marrow
False, by the kidney to increase production of erythrocytes
What systems regulate vitamin D?
Integumentary system, urinary, and digestive system
Once urine leaves the kidney can it get changed or altered
No
Kidney
Bean shaped organ
-Produces urine
Ureter
Tube that drains from kidney
Urinary bladder
Hollow muscular organ that holds urine
Urethra
Illuminates urine outside of body
Retroperatonial
Organs behind Paritoneum
Which kidney is lower
Right kidney
What is the root of the kidney?
Renal hilum
Adipose tissue
Engulfs renal capsule in acts as cushioning
Renal capsule
Surrounds each kidney
Renal facia
Anchors kidneys in surrounding adipose to abdomen wall
What exit renal hilum
Ureter, renal vein
What enters renal hilum?
Renal artery and nerve
Renal column
In between renal pyramids
-Also an extension of renal cortex
Renal pelvis
From major calyx merging
-Will turn into a ureter
Flow of urine
Kidney, ureter, urinary bladder, urethra
Nephron
Basic functional unit of kidney
Peritubular capillary
Second set of capillary
Efferent arterial
Blood vessel, that drains
Afferent arteriole
Blood that moves into Bowmans capsule
Renal corpuscle structure
Bowmans capsule: outermost structure
Bowman space : space in between
Glomerulus: first net work of capillaries
Podocytes: saw that has many foot processes
What is the first net work of capillaries?
Glomerulus
What is proximal convoluted tubule
Tubed structure
Contents of loop of Henle (nephron loop)
-thick and thin descending loop
Thick and thin, ascending loop
Distal convoluted tubule
Moves close to Bowmans capsule’s
Path of filtrate/urine produced by nephron
Renal corpuscle, PCT, filtrate, loop of Henley, DCT, CD urine, minor, calyx, major calyx, renal pelvis, ureter, urinary bladder, urethra
Will the afferent arterial give rise to Paritonium, capillary directly?
False it’s glomerulus first
- then efferent
Medulla
Collecting duct
Descending thin loop
Ascending thin loop
Cortex
Renal corpuscle
Proximal conveluted tubule
