Cards

Term
Aldosterone
Definition
promotes ion exchange at the distal convoluted tubule and renin leads to secretion of aldosterone
Term
Excretion
Definition
removes metabolic waste from the body.
Term
defecation
Definition
removes undigested food and bacteria from the body
Term
urinary system
Definition
does not maintain blood glucose levels
Term
Penicillin
Definition
actively transported from blood during tubular secretion into kidney tubule
Term
what color is the breakdown of hemoglobin
Definition
yellow
Term
kidneys
Definition
remove and excrete excess hydrogen from the blood in order to maintain a blood pH of 7.4
Term
Three layers of the wall of a ureter
Definition
mucous membrane, smooth muscle layer, and a fibrous connective tissue
Term
what is the pH of blood?
Definition
7.4-- slightly basic
Term
cystitis
Definition
an infection of the urinary bladder
Term
how many kidneys, bladders and ureters
Definition
two kidneys, one bladder, two ureters.
Term
filtrate
Definition
filtrate moves from the glomerulus to the proximal convoluted tubule, through the descending limb and then ascending limb and finally to the collecting duct.
Term
cellular respiration
Definition
produces carbon dioxide, which combines with water to form carbonic acid, thereby lowering the pH of the blood.
Term
how many openings of the urinary bladder
Definition
three -- one fore the urethra and two for the ureters
Term
renel pelvis
Definition
the renel pelvis is a central space that is continuous with the ureter
Term
the glomerulus
Definition
a knot of capillaries located inside the glomerular capsule
Term
podocytes
Definition
cling to the capillary walls of the glomerulus within the glomerular capsule
Term
Hydrogen
Definition
hydrogen is sctively secreted from the peritubular capillary network into the convoluted tubules.
Term
because the level of glucose is so high in the blood and carriers for glucose reabsorbtion reach their maximum rate of transport
Definition
excess glucose remains in the urine
Term
glucose and amino acids are reabsorbed where?
Definition
at the proximal convoluted tubule.
Term
hypothalamus
Definition
produces ADH if our water intact has been too low
Term
erythropoietin
Definition
a hormone secreted by the kidneys
Term
ANH
Definition
inhibits the secretion of renin by the juxtaglomerular apparatus
Term
first signs of nephron damage
Definition
albumin, white blood cells, and or red blood cells in the urine
