1
Q

urination

A

eliminates waste products that accumulate as a result of cellular metabolism

2
Q

functions of urinary system

A

excretion of waste to maintain volume and chemical composition of blood

3
Q

functions of kidneys

A
  • maintain appropriate blood volume by varying the excretion of water in the urine
  • maintain chemical composition of blood by selecting certain chemicals to excrete
  • maintain blood pH
  • excrete waste products of protein metabolism
  • regulation of blood pressure
  • stimulation of erythrocyte (RBC) production by secreting erythropoietin

  • urinary bladder
23
Q

nephron

A

functional unit of kidney; each kidney contains 1 million

24
Q

tubules

A

tubular sections of the nephron; reabsorption of water, electrolytes, and other substances occurs across the tubule walls into the blood capillaries

25
Q

glomerulus

A

cluster of blood vessels in a nephron surrounded by Bowman’s capsule

26
Q

three processes of urine formation (functions of the nephron)

A

glomerular filtration: glomerulus allows water, salts, wastes, etc. to pass from blood into Bowman’s capsule

tubular reabsorption: reabsorption of substances that the body conserves, such as sugar and water, from tubules into blood vessels

tubular secretion: secretion of substances from blood stream (waste products of metabolisms and drugs) into renal tubule

27
Q

urinalysis

A

analysis of urine (typically for sugar, protein, and blood)

28
Q

glycosuria

A

presence of sugar in urine

29
Q

proteinuria

A

presence of protein in urine

30
Q

hematuria

A

presence of blood in urine

31
Q

ketonuria

A

presence of ketones in the urine (when fat stores are metabolized for energy)

32
Q

diabetes mellitus

A

endocrine disorder characterized by glycosuria and hyperglycemia (inc glucose in blood) and results from inadequate production of insulin

33
Q

catheter

A

instrument inserted in urethra up to bladder for collecting urine

34
Q

BUN (blood urea nitrogen)

A

measure of amount of urea in blood; directly related to metabolic function of liver and excretory function of kidneys

35
Q

creatinine

A

substance measured in blood and urine as indicator of kidney function

36
Q

A

radiographic study to assess arterial blood supply to kidneys

37
Q
