answer: A.
NERVOUS, MUSCULAR, SKELETAL
The three human-body systems coordinate
to cause an arm to move are the nervous system, muscular system and
skeletal system.
To simplify, the brain will signal the whole body to move the arms, nerves on
the muscular will respond by making the bones of the arm move.
Nervous system recognizes as well as coordinates the response of our body to
changes in its internal and external environments. While, the muscular system
is working with our skeletal system to produce voluntary movement as it also
helps to circulate the blood and move food through the digestive system. Last
but not the least is the skeletal system that supports the human body. It in
fact protects human’s internal organs and also allows movements. Our skeletal
system stores mineral reserves and provides site for the formation of our blood
cells.

***************************
Letter B respiratory, muscular, digestive - incorrect because, the respiratory
regulates the breathing of the body while digestive system is being used when
we are eating and / or defecating. Lungs and stomach aren’t involved when we
are moving our arms.
Letter C skeletal, circulatory, immune – is incorrect
too because circulatory system and immune system are for the regulation of our blood,
cells and immunity.
Letter D digestive, nervous, circulatory – is incorrect,
too. Rely on the explanation for Letter B and Letter C.

**************************
Nervous system includes brain,
spinal cord, and somatic nerves and all sensory organs.
It also includes those that serve senses such as vision, smell, sensation,
balance, hearing and taste.
Nervous system is of course involved in moving our arms as it coordinates body
movements and controls responses to both external and internal stimuli.
It can serve as the center for our intellect and memories that can also
regulate moods and provides mechanisms for human interaction.
Muscular system includes skeletal muscles.
It is involved in moving our arms because muscular system provides locomotion
and support as it allows us to manipulate our atmospheres as it could produces
heat, too.
Skeletal system this includes bones, joints,
cartilage, tendons, and ligaments.
Skeleton provides structural protection for our internal organs and this is why
it is involved in moving our arms.
Skeleton or our bones are like the reservoir for calcium, phosphorus, and
magnesium that are crucial in array of physiological processes.
