kidney

Back 1

Front 2

renal cortex

Back 2

outer granular appearing part of the kidney

Front 3

renal pelvis

a cavity in the center of the kidney formed by the expanded, proximal portion of the ureter, lying within the kidney & into which the major--

Front 4

renal medulla

Back 4

inner striated appearing red-brown region

Back 5

functional unit of the kidney

Front 6

glomerulus

Back 6

a rounded mass of nerves or blood vessels, especially the microscopic tuft of capillaries that is surrounded by the glomerular capsule of each kidney tubule

Front 7

bowman's capsule

Back 7

cortex that the renal tubule lies in/ inside is a glomerulus

Front 8

loop of henle

Back 8

loop that fluids & solutes pass into

urine

Back 9

fluid produced by the kidneys that contains wastes or excess materials and is excreted from the body through the urethra

Front 10

glomerular filtration

Back 10

the first step in urine formation in which substances in blood are filtered at the filtering membrane & the filtrate enters the proximal convulated tubule of a nephron

Front 11

tubular reabsorption

Back 11

the movement of filtrate from renal tubules back into blood in response to the body's specific needs

Front 12

tubular secretion

Back 12

the movement of substances in blood back into blood in response to the body's specific needs

Front 13

glomerular filtrate

Back 13

consists of all the materials present in the blood except for the formed elements & most proteins

Front 14

net filtration pressure

Back 14

net pressure that expresses the relationship between the forces that promote fluid movement at the arterial & venous ends of a capillary & that promote glomerular filtration in the kidneys

Front 15

renin

Back 15

an enzyme released by the kidney into the plasma where it converts angiotensinogen into angiotensin I

Back 23

inflammation of the urinary bladder

Front 24

nephrotic syndrome

Back 24

protein in the urine, primarily albumin, that results in low blood level of albumin, edema, & high blood levels of cholesterol, phospholipids, & triglycerides/caused by increased permeability of the filtering membrane
