LESSON 11 PART 4 Flashcards
what are being filtrated during the glomerular filtration?
water and solute smaller than proteins
what are being reabsorbed in the tubular reabsorption?
water, glucose, amino acids and needed ions
what are being removed during tubular secretion?
H+, K+, creatinine and drugs
the tubular secretion removes unwanted substances from the ___________.
peritubular blood
Non-selective, passive process in which fluid passes from the blood into the glomerular capsule part of the renal tubule.
glomerular filtration
Reverse of tubular reabsorption
tubular secretion
where do most tubular reabsorption occurs?
at the proximal convoluted tubules
Tubule cells are “transporters,” taking up needed substances from the filtrate and then passing them out their posterior aspect into the extracellular space, from which they are absorbed into peritubular capillary blood. what process does the description fit into?
tubular reabsorption
Begins as soon as the filtrate enters the proximal convoluted tubule
tubular reabsorption
the oliguria acquire how many ml ?
100-400ml/day
the anuria acquires how many ml?
<100 ml/day
they take up the needed substances from the filtrate and pass them out their posterior aspect into the extracellular space, from which they are absorbed into peritubular capillary blood.
tubule cells
what is the formula for the excretion rate?
ER=FR-RAR-SR
another term for peeing?
micturition
what process does this refer to? freely filtered but not reabsorbed nor secreted
filtration only
what process does this refer to?All the filtered substance is reabsorbed
filtration, complete reabsorption
what process does this refer to? Urinary excretion < rate of filtration
filtration, partial reabsorption
Substance is freely filtered and additional quantities are secreted from the peritubular capillaries into the tubules
filtration, secretion
filtration and secretion usually occurs on?
organic acids and bases
filtration, complete reabsorption usually occurs to the?
amino acids and glucose and water
the bladder innervated by the?
autonomic nervous system : parasympathetic and sympathetic
what allows the relaxation of the detrusor muscle?
sympathetic
allows the relaxation in the sphincter
parasympathtic
refers to the increase in pressure that last from a few seconds to more than a minute?
micturition waves
relationship of bladder and micturition contraction??
as the bladder acquires more urine the greater the pressure will be the micturition contraction
who exerts final control of micturition?
the higher centers, pons and cerebellum
what is being contracted by the higher centers? what is being relaxed by the higher center in order to promote peeing?
external bladder sphincter, corticol centers- external urethral sphincter
how does voluntary urination occur?
through the contraction of the abdominal muscles thus exciting the micturition reflex and simultaneously inhibits the external urethral sphincter
what is the first column of the urinalysis called?
physical examination
what is the second column of the urinalysis?
microscopic examination
range of red to orange, and even to other colors like black.
pee
it is to examine if it’s clear, turbid, or cloudy.
transparency
is the comparison of your urine to your distilled water which has 0 solutes.
specific gravity
