Why is breathing necessary for humans?
A. Breathing allows us to take in oxygen needed for cellular respiration
B. Breathing allows us to take in oxygen needed for photosynthesis
C. Breathing allows us to take in CO2 needed for cellular respiration

helps fight infections are
Folds of connective tissue that stretch across the opening of the larynx is/are
the vocal cords

Select the correct order of the respiratory system:
Mouth/nose - trachea - lungs
Lungs - mouth - heart
Mouth/nose - ribs - heart
Mouth/nose - lungs - intestines
How do your circulatory and respiratory systems work together?
Your heart protects your lungs
Lungs bring food into the body for your blood
Oxygen and carbon dioxide are exchanged between your lungs and blood.
The respiratory system makes blood for your circulatory system
