How do sound waves travel through air?

Back

Sound waves cause air particles to vibrate, which transmits the sound.

Front

What is the function of the respiratory system?

Back

The respiratory system is responsible for taking in oxygen and expelling carbon dioxide.

Front

How does the respiratory system interact with the circulatory system?

Back

The respiratory system provides oxygen to the circulatory system, which then delivers it to cells.

Front

What is photosynthesis?

Back

Photosynthesis is the process by which green plants use sunlight to convert carbon dioxide and water into glucose and oxygen.

Front

What are mitochondria?

Back

Mitochondria are organelles in cells that produce energy through cellular respiration.

Front

What is the function of red blood cells?

Back

Red blood cells transport oxygen from the lungs to the body's tissues and carry carbon dioxide back to the lungs.
