Urinary system


Function get rid of waste
Kidneys located posterior abdominal wall protected by back fat, redish brown
Fibrous capsule outer layer
Renal cortex the lighter outer region
Renal Medulla forms striped, cone-shaped regions called renal phyramid
Sympathetic nerve stimulation
Renal Phyramid houses the neuphron unit
Nephron Unit makes urine, absorbs water
Nephron Unit takes waste out of blood
Nephron Unit Regulates blood volume, regulate blood pressure
Calyx collects the pee from the Renal Phyramid
Renal Pelvis holding tank
Ureter Connects to the bladder, carries the urine to the bladder
Glomerulus Oxygenated blood
Aferent arteriole going in
Efferent arteriole going out
Pentubular Capillery around the tube capillery
Bowmons Capillery helps exchange nutrients from the glonierulus
Tubular secretion moves small amount of substance from blood to tubules
Tubular reabsorption water and disolved substance move from the tubulus into the blood of peritubular capillaries
Glomerular filtrate water and dissolved substances into Bowmans capsule
Glomerular filtration rate at which glomerular filtration occurs
Aldosterone salt retaining hormone, comes from adrenal cortex
Renin angiotensin aldosterone system end result of this system is to increase blood pressure
Juxtaglomerular apparatus barorecpter, located in the afferent arterioles
Juxtaglomerular apparatus secretes renin when senses low blood pressure
Artrial natriuretic peptide sense high blood pressure
Urine 95% water
Clear Urine drank a lot
Urine sterile
Specific gravity weight of urine
Urine pH-6
Innermost layer of bladder Mucus
Detruser muscle muscle layer
Brain natriuretic peptide decreases the reabsorption of sodium
Brain natriuretic peptide causes greater excretion of sodium and water by the kidney
Antidiuretic Hormone stimulates the reabsorption of water
Parathyroid hormone stimulates the reabsorption of calcuim and excretion of phosphate
Angiotensinogen Renin activates this to form angiotensin 1
Angiotentensin 1 secreted by the liver and circulates within the blood
Converting enzyme enzyme which acts to change angiotensin 1 to angiotensin 2
angiotensin 2 stimulates the adrenal cortex to release aldosterone
Aldosterone stimulates the distal tube to reabsorb sodium and water and to excrete potassium
collecting duct ADH likes to work here
Secretion out
Absorption In
Adrenal Cortex Stimulates Aldosterone
Distal Tubular reabsorb sodium
ADH Takes out
Diaretic makes you pee
Mucus lines the organs
two kidneys
two ureters
one bladder
one urethra
