Osmotic balance Flashcards
Acidosis
lower than normal pH level
ADH
antidiuretic hormone - released from the neurohypophysis
Aldosteron
steroid hormone of the adrenal gland
Alkalosis
higher than normal pH level
ANP
atrial natriuretic peptid - secreted in the atrium of the heart
Bilirubin
yellowish bile pigment produced by breakdown of heme
Clearance
a functional measure of the kidney function
Cortical nephron
the most frequent nephron type located in the cortex of the kidney with short Henle´s loop
Diuresis
discharge of urine from the urinary bladder
Diuretics
drugs that increase the amount of urine and urination
Facultative reabsorption
controlled reuptake of certain elements of the primary urine
GFR
(glomerual filtration rate) the amount of fluid filtrated per unit of time in the glomeruli of the kidneys
Glomerulus
the functional unit of the kidneys
Henle´s loop
a tubule connecting the proximal and the distal tubules in the kidneys
Juxtaglomerular apparatus (JGA)
cell-group located in the angular area of the glomerulus and the tubules in the nephrons that produces renin
Juxtamedullary nephron
nephron located close to the corticomedullary border in the kidney
Nephron
functional and anatomical unit of the kidneys
Obligate reabsorption
the compulsory reabsorption under any circumstances of a portion of some materials
Podocyte
epithelial cell type in the Bowman´s capsule
RBF
(renal blood flow), the amount of blood flowing through the kidneys per unit of time
Reabsorption
backward transport of some ultrafiltrated materials from the tubules to the blood vessels in the kidneys
Renin
peptide hormone released by the juxtaglomerual apparatus
RPF
(renal plasma flow), the amount of blood plasma flowing through the kidneys per unit of time
Tubular maximum
a rate limit of transport proteins in the kidney tubules above which only a portion of the given material is reabsorbed
