(opening the door) describe the work of at least 3 body organ Systems that work during the process.
My name is Ann [436]
Explanation:

When a person opens the door, he or she uses 3 systems:

1. Nervous system: from the nervous system, neural instructions are generated through electrical impulses towards the muscles of the upper limb so that they make the necessary movements to open the door.

2. Muscular system: through the muscles of the trunk and the upper limb, it generates voluntary movement to open the door.

3. Skeletal system: the bones are the support of the soft tissues and the fulcrum of most of the skeletal muscles. In this sense, it serves as a support for the muscles of the trunk and the upper limb to carry out the movement of opening the door.

we can conclude that the correct answer is:

Answer:

1. Nervous system: instructions are generated from the nervous system by means of electrical impulses towards the muscles of the upper limb so that they carry out the necessary movements to open the door.

2. Muscular system: the muscles of the trunk and the upper limb generate voluntary movement to open the door.

3. Skeletal system: it supports the muscles of the trunk and the upper limb to carry out the door opening movement. It also has joints that help the mechanical movements necessary to open the door.
