Kidney Anatomy
*outer to inner portion
*what does each do? - Correct Answer*Fibrous capsule
-protects and keeps everything contained within the kidneys
*Renal cortex
-contains blood vessels and nephrons (functional unit of the kidney)
*Medulla
-tiny tubules collect waste (urine) that has been filtered out by the nephrons
*Renal Pelvis
-collects urine and sends it on to eventually reach the bladder
Jobs of the Kidney - Correct Answer*eliminate waste
*regulate fluid volume
*regulate electrolytes
*maintain acid-base balance
*regulating BP
*regulating RBC production
*turning vitamin D into active form
Uremia
*definition
*happens due to?
*s/s - Correct Answer*urine in the blood
*happens if kidneys can't remove waste and it builds up within the blood
*s/s:
-confusion
-GI problems
-classic uremic frost (waste builds up in the blood and begins to escape through pores
of skin)
Ureters - Correct AnswerThe tubes that carry urine from the kidneys to the bladder.
, Bladder - Correct AnswerElastic, hollow, muscular organ (lined by mucus membranes)
that provides temporary storage for urine.
Urethra
*definition
*has what? - Correct Answer*tube leading from the urinary bladder to the outside of the
body
*internal (involuntary) and external (voluntary) sphincter
Nephron
*definition
*what does it do?
*how many in each kidney?
*contains what? - Correct Answer*the functional unit of kidneys
*filters waste out of kidneys
*~ 1 million
*contains:
-glomerulus
-bowman's capsule
-blood vessels
-tubules
Glomerulus
*what is it?
*What gets filtered out when blood flows through?
*how does this happen? - Correct Answer*collection of blood vessels (looks like bowel
of spaghetti) that sits in a capsule called "Bowman's capsule"
*substances like ions, electrolytes, gucose, and salts
*filtration
-the pressure (caused by BP) pushes those small substances out into the Bowman's
capsule
Hormones in the urinary tract - Correct Answer*aldosterone
*antidiuretic hormone (ADH)
*atrial natriuretic hormone
*erythropoietin
