Musculoskeletal-Nervous-Endocrine

As you are sleeping, which of the following is true about the body systems?

• All of your systems shut down

• All of your systems continue to function to maintain homeostasis

• Only your nervous system continues to function

• All of your systems speed up.

In order to maintain homeostasis, the systems of the human body work together to keep a constant internal temperature. which of the following best describes how the human body responds in a cold environment?

• The nervous system signals the muscles of the muscular system to contract and warm the body.

• The skeletal system produces more blood cells that circulate through he body vessels, increasing the warmth of the body.

• The digestive system produces more hormones to warm the body.

• The circulatory system delivers less carbon dioxide to the muscular system, resulting in stiffening of the muscles.

The interaction of the skeletal and muscular systems to produce movement is coordinated by which human body system?

• Respiratory

• Circulatory

• Nervous

• Excretory

Which two body systems make movement possible?

• The lymphatic and immune systems

• The skeletal and muscular systems

• The cardiovascular and respiratory systems

• The nervous and endocrine systems

Organ systems work together to meet the needs of the human body. How is the skeletal system related to the nervous system?

• The brain determines how the skeleton develops.

• The brain and spinal cord hold the skeleton together.

• The skeletal system works as part of the nervous system.

• The skeleton protects the brain and spinal cord.

Children have a different number of bones than adults do. Why is this the case?

• As children develop, some of their bones fuse together, and adults have fewer bones as a result.

• As children develop, their bones become damaged and they experience bone loss, and adults have fewer bones as a result.

• As children develop, they grow new bones, and adults have more bones as a result.

• As children develop, some of their bones separate into smaller bones, and adults have more bones as a result.

Which of the following is an example of voluntary muscle action?

• pupils dilating in reaction to light

• the heart pumping blood through the body

• fingers typing on a keyboard

• the stomach moving food to the intestines.

What are hormones?

• specialized cells that destroy bacteria an viruses

• chemical messengers that are produced in one type of tissue and cause changes in another type of tissue.

• chemical messengers that are produced in bone marrow that are used to control body function.

• specialized cells that control growth and metabolism.
