Questions: Which system helps to move the body? integumentary muscular endocrine cardiovascular

The answer is the second one (muscular): the muscular system helps to move the body.

Explanation for each option:

1. Integumentary: This system includes the skin, hair, nails, and associated glands. It primarily serves as a barrier to protect the body from the outside environment, helps regulate body temperature, and provides sensory information. It does not directly facilitate movement.

2. Muscular: The muscular system is responsible for movement. It consists of muscles that contract and relax to produce motion, whether it's voluntary movements like walking or involuntary movements like the beating of the heart.

3. Endocrine: This system consists of glands that secrete hormones into the bloodstream. It regulates various body functions such as metabolism, growth, and mood, but it does not directly cause movement.

4. Cardiovascular: This system includes the heart and blood vessels. It is responsible for circulating blood throughout the body, delivering oxygen and nutrients to tissues, and removing waste products. While it supports the muscular system by providing necessary nutrients and oxygen, it does not directly cause movement.

In summary, the muscular system is the one that directly facilitates movement in the body.
