first step in urine formation is —- filtration

glomerular

three major steps of urine formation are —-, —-, and ——

glomerular filtration, tubular reabsorption, and tubular secretion

glomerular filtration occurs before tubular

reabsorption

tubular secretion moves substances from the blood into the tubular —-

fluid

filtration of plasma to form filtrate occurs in the —-

glomerulus

renal corpuscle consists of the glomerulus and —- capsule

bowman’s

part of the nephron responsible for glomerular filtration is the ——-

renal corpuscle

glomerulus is a tuft of specialized —-

capillaries

filtrate formed in the glomerulus enters —- capsule

bowman’s

outward force favoring filtration is glomerular —- pressure

hydrostatic

blood colloid osmotic pressure acts —- filtration

against

capsular hydrostatic pressure also acts against —-

filtration

net filtration depends on the balance of opposing and favoring —-

pressures

in a fasting urine sample, finding — is considered abnormal

glucose

normal urine commonly contains water, sodium, urea and other dissolved —-

solutes

proteins in the urine are usually considered —-

abnormal

red blood cells in the urine are generally considered ——

abnormal

glucose in the urine may suggest abnormal blood glucose regulation or impaired tubular —-

reabsorption

dipstick urinalysis results are determined by comparing pad —- to a standard chart

colors

a urine dipstick uses chemical indicator —-

pads

descending limb of the nephron loop reabsorbs —-

water

descending limb helps increase medullary —

osmolarity

proximal convoluted tubule reabsorbs about —-% of the filtrate

80

proximal convoluted tubule reabsorbs glucose, amino acids, and —-

water

distal tubule has permeability controlled by —-

hormones

distal tubule can reabsorb additional sodium and —-

water

bowman’s capsule receives —- from the glomerulus

filtrate

collecting duct helps regulate final water —-

reabsorption

loop of henle helps create a concentration —- in the medulla

gradient

tubular reabsorption moves substances from the filtrate back into the —-

blood

some blood solutes not filtered at the renal corpuscle can still enter tubular fluid by tubular —-

secretion

tubular secretion helps eliminate excess ions, wastes, and certain —-

drugs

reabsorption prevents loss of useful substances such as glucose and —- acids

amino

health kidneys filter blood plasma while retaining most blood—-

cells

urinalysis can help detect abnormalities in kidney function and —- health

metabolic
