Which statement correctly describes two organ systems working together when the body increases its movement?

A. The excretory system releases extra waste, and the digestive systems breaks down nutrients quickly to replace the waste.

B. The digestive system breaks down nutrients quickly, and the respiratory system delivers the nutrients to the working muscles.

C. The respiratory system increases gas exchange, and the circulatory system circulates blood faster to deliver oxygen to muscles.

D. The circulatory system picks up more carbon dioxide waste from the muscles, and the excretory system releases the carbon dioxide.

The respiratory system provides oxygen to the blood in the body, while removing carbon dioxide. Which system directly interacts with the respiratory system to maintain homeostasis?

A. the excretory system when it sends out liquid waste as urea

B. the skeletal system when oxygen and glucose around the ribs are absorbed

C. the nervous system when the brain regulates the body’s breathing and heart rate

D. the digestive system when food is broke n down for nutrients


The job of tendons in the muscular system is to

A. connect muscles to bones

B. control protein synthesis

C. transmit nerve signals

D. repair damaged cells


What is an example of the muscular system and the nervous system interacting to maintain homeostasis?

B. A leg muscle provides energy to the brain.

C. A rib bone moves oxygen and glucose to the brain.

D. The skull provides nutrients for brain growth and repair.


What are the main functions of the human skeleton?

A. exchange of gases

B. support and movement

When a doctor checks the reflex of your knee, which body systems are being tested?

A. respiratory and excretory

B. excretory and muscular

C. muscular and nervous

D. nervous and digestive


The spinal cord, a long tubular structure, that connects to the brain, is protected by the vertebrae. In this situation the

A. endocrine system works in conjunction with the respiratory system

B. nervous system works in conjunction with the skeletal system

C. digestive system works in conjunction with the excretory system

D. muscular system works in conjunction with the nervous system


Which statement provides the best evidence that the muscular system interacts with the respiratory system to carry out life processes?

A. The absorption of oxygen by sacs called alveoli shows how specialized tissues are necessary for movement of substances through the respiratory system.

B. The initiation of the breathing process by the phrenic nerves shows how neurons are necessary for blood oxygenation.

C. The protection provided by the rib bones shows how the respiratory system needs hardened organs to keep it working properly.

D. The diaphragm’s movement downward to draw air into the lungs shows how muscles are necessary to bring air into the body.


What is the main function of the skeletal system in relation to the muscular system?
