Urinary 1
What is an inorganic substance that disassociates into ions in a solution?
electrolyte
This part of the urinary system are retroperitoneal organs attached to the posterior abdominal wall
Kidneys
What are the parts of the renal tubule?
nephron loop, collecting duct, PCT, DCT
The indentation of the kidney
hilum
What selective process reclaims materials from tubular fluid and returns it to the blood stream?
tubular reabsorption
This is where two-thirds of the body fluid is located
intracellular fluid
What are the correct order of the layers covering the kidneys from deep to superficial?
renal capsule, adipose capsul, renal fascia
What are the three processes that glomerular filtration rate (GFR) depends on?
renal autoregulation, neural regulation, hormonal regulation
If this hormone is present, the kidneys will produce concentrated urine
ADH
What is the most abundant extracellular ion?
Na
What is the normal pH of systemic arterial blood?
7.35-7.45
The muscular tubes that transport urine from the kidneys to the bladder
ureters
The amount of glomerular filtrate filtered through the glomerular filter per day
180L
The medulla of the kidneys forms 6-18 conical structures known as?
renal pyramids
What part of the urinary system filters wast products, toxins, and excess fluid from the blood stream?
Name a function of the kidneys
The kidneys regulate blood ionic composition, blood osmolarity, blood volume, blood pressure, and blood pH. The kidneys also perform gluconeogenesis, release calcitriol and erythropoietin, and excrete wastes and foreign substances.
which reabsorption route happens across tubule cells
transcellular
The cup shaped structures into which any urine formed in the kidneys drains into
renal calyces
What percent of filtered water is reabsorbed in the nephron loop?
15%
What happens when systemic arterial blood pH is above normal?
alkalosis
What is the average glomerular filtration rate (GFR)?
105-125 mL/min
This nephron has a short loop that dips only into the superficial region of the renal medulla
cortical
The smooth muscle of the bladder wall
detrusor
What are the main (3) parts of the nephron?
glomerulus, glomerular capsule, renal tubule
What are the three basic tasks of the nephron?
glomerular filtration, tubular sectretion, tubular reabsorption
