Front 28

what hs nephrons which are the outer functional unitofthe kidney?

Back 28

renal cortex

Front 29

What is the primary function of the kidneys?

Back 29

removal of fluid, waste by diluting in water then excreting

Back 30

renal corpuscle and renal tubule

Front 31

fluid flows through the what on the way out of the body?

Back 31

renal tubules

Front 32

what is the filtering portion of the nephron?

Back 32

renal corpuscle

Front 33

what is the renal corpuscle made up of?

Back 33

a ball of capillaries called the glomerulus and a glomerular capsulethat recives the filtrate

Front 34

What filters the fluid and is the first step in urine formation?

Back 34

glomerulus

Front 35

What surrounds the glomerulus?

Back 35

the glomerular capsule

Front 36

what leads away from the glomerular capsule?

Back 36

the renal tubele

Front 37

what joins to becomethe collecting ducts?

Back 37

convoluted tubules

Front 38

The glomerular filtration produces how many liters of fluid a day?

Back 38

180 that is 4x total body water every 24 hrs

Front 39

what moves substances fromthe tubular fluidbackinto the blood?

Back 39

Tubular reabsorbtion

Front 40

what is reasorbed by the tubular reabsorbtion?

Back 40

Glucose amino acids and water

Front 41

what moves substances from the bloodto the the renal tubule?

Back 41

tubular secretion

Front 42

What three processes make urine?

Back 42

Glomerular filtration, tubular reabsorption,tubular secretion

Front 43

what conveys urine tothe urinary bladder

wht is urination or the process that expels urine from the urinary bladder?

Back 44

Micturition

Front 45

Which of the following comprises the kidney's transport system

Back 45

tubules and pelvis

Which of the following renal structures is found in the medulla of the kidney

Back 47

collecting duct

Front 48

High pressure is maintained in the glomerulus because

Back 48

the wall of an arteriole is less compliant than that of a venule the diameter of the efferent arteriole is less than that of the afferent arteriole
