Interactions
Integumentary System
- Evaporative water loss from
the skin helps control body
temperature, but effects on blood
volume must be compensated for
by the kidneys (p. 459) - The skin produces vitamin D 3 ,
which is activated in the kidneys
(p. 693) - The kidneys maintain homeostasis
of blood volume, pressure, and
composition, which is needed for
the health of the integumentary and
other systems (p. 582)
Skeletal System
- The pelvic girdle supports and
protects some organs of the urinary
system (p. 582) - Bones store calcium and
phosphate, and thus cooperate
with the kidneys to regulate the
blood levels of these ions (p. 690)
Muscular System
- Muscles in the urinary tract assist
the storage and voiding of urine
(p. 584) - Smooth muscles in the renal blood
vessels regulate renal blood flow,
and thus the glomerular filtration
rate (p. 589)
Nervous System
- Autonomic nerves help regulate
renal blood flow, and hence
glomerular filtration (p. 589) - The nervous system provides motor
control of micturition (p. 584)
Endocrine System
- Antidiuretic hormone stimulates
reabsorption of water from the renal
tubules (p. 597) - Aldosterone stimulates sodium
reabsorption and potassium
secretion by the kidneys (p. 605)- Natriuretic hormone stimulates
sodium excretion by the kidneys
(p. 607) - The kidneys produce the hormone
erythropoietin (p. 410) - The kidneys secrete renin, which
activates the renin-angiotensin-
aldosterone system
(p. 606)
- Natriuretic hormone stimulates
Circulatory System
- The blood transports oxygen and
nutrients to all systems, including
the urinary system, and removes
wastes (p. 405) - The heart secretes atrial natriuretic
peptide, which helps to regulate the
kidneys (p. 462) - Erythropoietin from the kidneys
stimulates red blood cell production
(p. 410) - The kidneys filter the blood to
produce urine, while regulating
blood volume, composition, and
pressure (p. 582)
Immune System
- The immune system protects all
systems, including the urinary
system, against infections (p. 494) - Lymphatic vessels help to maintain
a balance between blood and
interstitial fluid (p. 457) - The acidity of urine provides a
nonspecific defense against urinary
tract infection (p. 494)
Respiratory System
- The lungs provide oxygen and
eliminate carbon dioxide for all
systems, including the urinary
system (p. 533) - The lungs and kidneys cooperate in
the regulation of blood pH (p. 568)
Digestive System
- The GI tract provides nutrients for
all tissues, including those of the
urinary system (p. 620) - The digestive system, like the
urinary system, helps to eliminate
waste products (p. 638)
Reproductive System
- The urethra of a male passes
through the penis and can eject
either urine or semen (p. 719) - The kidneys participate in the
regulation of blood volume and
pressure, which is required for
functioning of the reproductive
system (p. 582) - The mother’s urinary system
eliminates metabolic wastes from
the fetus (p. 742)
