The kidneys store excess nutrients and energy.
The kidneys produce hormones and regulate blood pressure.
What is the difference between voluntary and involuntary muscles?
Voluntary muscles are consciously controlled; involuntary muscles are not.
Voluntary muscles are responsible for digestion.
Involuntary muscles can be controlled at will.
Voluntary muscles are found only in the heart.
How do the skeletal and muscular systems work together?
The skeletal system provides energy for muscle contractions.
The skeletal and muscular systems work together to enable movement and provide support to the body.
