parts.

Muscular System
Integumentary System
The skin increases
heat loss during
skeletal muscle
activity. Sensory
receptors function
in the reflex control
of skeletal muscles.
Skeletal System
Bones provide
attachments that
allow skeletal
muscles to cause
movement.
Nervous System
Neurons control
muscle
contractions.
Endocrine System
Hormones help
increase blood flow
to exercising
skeletal muscles.
Cardiovascular System
Blood flow delivers
oxygen and nutrients
and removes wastes.
Cardiac muscle pumps
blood, smooth muscle
in vessel walls enables
vasoconstriction,
vasodilation.
Lymphatic System
Muscle action
pumps lymph
through lymphatic
vessels.
Digestive System
Skeletal muscles
are important in
swallowing. Smooth
muscle moves
food through the
digestive tract. The
digestive system
absorbs needed
nutrients.
Respiratory System
Breathing depends
on skeletal muscles.
The lungs provide
oxygen for energy
releasing reactions
in muscle cells and
excrete carbon
dioxide waste from
those reactions.
Urinary System
Skeletal muscles
help control expulsion
of urine from the
urinary bladder.
Reproductive System
Skeletal muscles
are important in
sexual activity.
