Muscles that help the skeleton move...

Back

skeletal muscles

Front

Which organ functions as both a respiratory organ and an excretory organ? Options: the liver, the lungs, the skin, the kidneys

Back

the lungs

Front

What systems are involved in carrying nutrients and oxygen to muscle cells and removing CO2 and waste? Options: Cardiovascular/Circulatory & Muscular, Cardiovascular/Circulatory & Excretory, Respiratory & Muscular

Back

Cardiovascular/Circulatory & Muscular

Front

The brain checks the amount of CO2 in the blood and adjusts the rate of breathing. The brain "communicates" with the lungs using nerves from the brain to the lungs. Classify the systems involved.

Nervous & Respiratory

Front

Which systems are involved when the brain tells the stomach, intestines, and liver when to be active and when to rest?

Back

Nervous & Digestive

Front

Cardiovascular/Circulatory & Digestive

Front

What systems are involved when muscles in the intestines continually contract and break down food into nutrients the body can absorb?

Back

Digestive & Muscular

Front

Red blood cells go to the lungs to remove CO2 and pick up O2 that has been inhaled. The heart pumps red blood cells carrying O2 from the lungs to all cells in the body. Which systems are involved?

Back

Circulatory & Respiratory

Front

A friend throws you a ball. Your brain tells your hands to move to catch the ball. Options: Nervous & Respiratory, Nervous & Skeletal, Nervous & Muscular

Back

Nervous & Muscular

Front

When you're running, you breathe harder and your heart rate increases (pumping more blood) to get more oxygen to your cells to create energy.
Options: Cardiovascular/Circulatory & Nervous, Cardiovascular/Circulatory & Respiratory, Respiratory & Nervous
