Exam 26 Flashcards
An increase in the BCOP will ____________ the glomerular filtration rate
Decrease
“Cystitis” refers to inflammation of the
Bladder
Filtration occurs at the
Bowman’s capsule
Location of podocytes
Glomerular visceral epithelium
Most reabsorption occurs in the
Proximal convoluted tubule
Narrowing of the afferent glomerular arteriole will result in the ________ of systemic blood pressure
Increase
Secretion occurs mostly in the
Distal convoluted tuble
The counter current multiplication system uses
- The hyperosmotic renal medulla
- Sodium pumps of the ascending limb of the loop of henle
- Juxtamedullary nephrons
The countercurrent multiplication process
- Allows concentration of urine
- Occurs in the loop of henle
- Involves osmosis and sodium transport
- Uses the vasa recta
The fluid in the bowman’s space is
Filtrate
The fluid in the collecting duct is
Urine
The juxtaglomerular cells produce
Erythropoietin
Urine exits the kidney into the ureter from the
Renal pelvis
Which of the following is normally found in the urine?
- Bilirubin
- Urea
- Ammonia
- Phosphates
You are drinking liters of water for a lab experiment. Your urine is very diluted, also termed:
Hyposthenuric
Men have more problems with kidney stones than women due to their:
Longer and narrower urethra
Renal threshold of a substance has been passed when
- The transport maximum is exceeded
- Carrier proteins have be saturated
- Spillover of the substance into the urine occurs
Sympathetic nervous stimulation will cause vasoconstriction of the ___________ ___________ after a massive blood loss
afferent arteriole
The detrusor muscle is
Smooth muscle
The fluid in the glomerulus is
Blood
The macula densa is part of the
Juxtaglomerular apparatus
What is unique (only found in) the urinary system
Transitional epithelium
Which is more concentrated? Fluid in the:
Loop of Henle
Which is not normally found in high amount in normal urine sample?
- Protein
- Glucose
- White blood cells
- Red blood cells
None of the above
Which of the following is true?
- The kidneys lie outside of the peritoneal cavity
- Left kidney is higher than the right
- The kidney has a tough fibrous capsule
All of the above
A glomerulus is
A knot of capillaries within the renal capsule
A drug that inhibits angiotensin converting enzyme (ACE) may lead to which of the below
- Less secretion of aldosterone
- Increase urinary loss of sodium
- Reduction of blood pressure
- Decreased sodium reabsorption
All of the above
Antidiuretic hormone
increases the permeability of the collecting ducts to water
Blood colloid osmotic pressure (BCOP) in the glomerulus is generated by
Presence of large, non-diffusible proteins in blood plasma
Blood leaves the glomerulus through a blood vessel called the
efferent ateriole
Capillaries that surround the proximal convoluted tubules are
Peritubular capillaries
During the micturition reflex,
- Stimulation of stretch receptors in the bladder wall sends impulses to the sacral cord
- Parasympathetic motor neurons that control the detrusor muscle become active
- The internal sphincter is subconsciously relaxed
- The external sphincter is consciously relaxed
Functions of the urinary system include
- Regulation of bloodvolume and blood pressure
- Regulation of plasma concentration of certain ions
- Helping to stabilize blood pH
- conservation of valuable nutrients
One mechanism the kidney uses to raise systemic blood pressure is to
Increase secretion of renin by juxtaglomerular complex
The U-shaped segment of the nephron is the
Nephron loop (loop of henle)
Substances secreted by the distal convoluted tubule include
- Hydrogen ions
- Penicillin
- Creatinine
- Potassium ions
The filtration of plasma takes place in the
renal corpuscle
The cavity of the kidney that receives urine from the calyces is called the
renal pelvis
The kidneys not only remove waste products from the blood, they also assist in the regulation of
- Blood volume
- Blood pH
- Blood pressure
- Blood ion levels
The majority of glomeruli are located in the _____ of the kidney
Cortex
The outermost layer of the kidney is the
Fibrous capsule
The portion of the nephron that empties into the collecting duct is the
Distal convoluted tubule
The primary function of the proximal convoluted tubule is
Absorption of ions, organic molecules, vitamins, and water
The process of filtration is driven by
Blood hydrostatic pressure
The renal veins drain into the
Inferior vena cava
Urine is carried to the urinary bladder by
The ureters
Triangular or conical structures located in the renal medulla are called
Pyramids
Urine is eliminated through the
Uretha
Urine passes, in the order given, through which of the following structures?
Collecting duct, renal pelvis, ureter, bladder, urethra
Name the two buffer systems located in the PCT
Phosphates & ammonia
Which of the following is NOT part of the juxtaglomerular complex?
Podocytes
